I have a new piece of hardware for the 128 Internal ROM Socket. It uses the high capacity EPROMs (27010 1meg, 27020 2meg, 27040 4meg and 27080 8meg).
It comes in a 16k version ($8000 to $BFFF) for a maximum no. of 64 pages or 32k version ($8000 to $FFFF) for a maximum no. of 32 pages.
I need to know if there's an interest for this adapter before I invest anymore time and money on it.
I have a 16k version that has a 4meg EPROM full of programs that I use on my C128 and 128DCR.
Here is a list of the programs:
Merlin 128 v1.0 Promos 2.0
My Disk Editor Function keys
Viza Write 128 Viza Star 128
Seq Reader 128 Begin & End Adrs
Fastrac File copy Directory Editor
Color 80 column Basic Data Maker
Monitor 64 Basic Merge
Basic Merge + Maverick File Copy
Maverick Track Editor Single 41 Data copy
Dual 41 Data Copy Single Nybbler
Dual Nybbler Single 81 Data copy
Maverick File Tracer Maverick Track & Sector Editor
64K VDC RAM Test REU Test
I have a 32k version that has a 1meg EPROM with Key Dos, Servant and Basic 8 installed.
I have sent the adapters to airship hoping he would write a review on it. I would happy to answer any questions you might have, but I would like to wait until airship has written his review.
Dan...
I'm interested.
By the way I forgot to mention, it won't cost an arm and a leg either.
For the Adapter with an EPROM is $20.00 USD, without an EPROM is $15.00 USD.
Dan...
Plus postage to Oz ?
Shipping/handling separate and I'll mail it anywhere USPS can send it.
Dan...
I'm interested too :)
Do you have a picture of the pcb so we can see what it looks like?
You presented an impressive list of C128 function ROM's. Are they all commercial (in origin) or are some of them "homemade".
QuoteDo you have a picture of the pcb so we can see what it looks like?
I don't know how to up load a picture to the forum. If airship writes a review on the adapter, maybe he will post a picture with it.

Thank you very much for the pictures that you mailed me. I've taken the liberty to upload them here.
I think airship is right in assuming we'd rather want the 32K version. And very nice that no soldering is involved. Soldering on a 20-25 year old motherboard is not recommended :)
How do you decide which 16K or 32K ROM should be active? Via software?
What is the wire used for that's connected to another chip?

Back in the 1980's Info 64 magazine had a review of Vizastar 128 (and by deduction, Vizawrite 128, too) and mentioned that it carried extra memory in its required cartridge in order to run the program. One of my German friends told me that the cart was no more than a giant dongle which prevented the program from running without it. What exactly was in that cart? Why was it "time-consuming", as you said?

QuoteWhat exactly was in that cart? Why was it "time-consuming", as you said?
Robert, you really are curious about how I managed to remove the copy protection.
There is no copy protection on the disk and your friends from Germany are correct about the cartridge, but it's ROM only, you can't write to it. I converted both programs for internal ROM sometime in 1990. I even gave a demonstration at CUGKC back then. They had quite a few members at that time.
Anyway, let me see if I can remember what I did. The loader would only load small portions of the program at a time. At the end of each small portion were, I think, 3 bytes of data that the loader would use to load the next small portion. This is where the time consuming part enters the picture. I had to load each small portion one at a time to get the information for the next and so on until the whole program was loaded. There were quite a few small portions. I remember keeping notes as I went, so I could back track if I had to.
The cartridges have code in them, but I never tried to go through any of it to see if the program used it for anything other than a dongle.
The cartridges are still there only in internal ROM instead of cartridge ROM. The program is loaded in RAM and then before the program is started, a page is flipped to put the ROM portion for the program at $8000 in internal ROM.
I had to go through the program code to find where it accessed the cartridge ROM and change it to access internal ROM instead.
Now you know.
Dan...

I plan to put a something together after airship does his review. I'm sure he'll find something I'll have to fix.
I plan to put a manual together with instructions, how it works, Merlin source code, parts list, layout and schematic. Some may want to make their own adapter.
I will try to cover all the information you'll need to program your own EPROM. Lord willing, I'll be around to answer any questions you might have. Except when I'm on the lake fishing.

---------------------------------------------------------------
THE MEGABIT 128 INTERNAL ROM ADAPTER
For the C128/C128D Internal ROM Socket
Developed by D. C. Newbury
Review by Mark R. Brown
THE BASICS
The Megabit 128 internal ROM Adapter is a small circuit board that plugs into the internal expansion ROM socket on the Commodore 128 or C128D. Its purpose is to allow you to use high-capacity EPROMS: 27010 (1 meg.), 27020 (2 meg.), 27040 (4 meg.), or 27080 (8 meg.).
It's very easy to install. Since the board is longer than a standard EPROM, you have to bend down a couple of small disk caps on the 128 motherboard before you snap it into the internal ROM socket. There's also a pigtail with a clip that has to be attached to a pin on the U3 chip. Piece of cake. No soldering. Easily removed if you need to.
Newbury currently sells two different versions of the adapter board. One addresses up to 16K at a time; the other addresses up to 32K at once. Each is the same price: $15 PPD in the US. Each uses the same EPROMs; which you choose comes down to how big a memory space you need to have active at any one time. The 32K version lets you include bigger apps, like KeyDos, the Servant, and BASIC 8.
THE BARGAIN
An even better deal than just buying the bare board is to add five bucks and order either board with an EPROM preprogrammed with some apps and a nice menu program. This not only gives you a set of useful apps right out the gate, it means non-technical types can actually do something with this board.
Because if you want to do something of your own, you're on your own. While the developer is a very helpful guy, there's no easy way right now to get your own apps up and running on this board. Here's what he wrote back when I asked how to program my own EPROM apps for this board:
"I will have to put something together, like a separate manual that will have the commented ML listings for the auto start routine, menu and program loaders. It may take awhile."
Then he mentioned something about fishing.
Just remember that full support for developing your own menus and apps is planned. It's coming. Sometime. Also remember you're only paying $20 (shipping included) for the preprogrammed edition of either version of this little marvel. If it were $50 or more, I'd linger here awhile, complaining. But for twenty bucks I think that's more than fair.
Okay. Fine. So we're stuck for the time being with the programs and menu system he's burnt for us. So let's talk about that.
Because what's already included is a load and a half.
THE BYTES
When I turn on my C128 in 40-column mode and press F1, nothing happens. At least, nothing happens on my C128. It might be interference with JiffyDOS, since I get the JiffyDOS '@$' command with F1. I don't know, but I'm not going to pull my JiffyDOS chip to find out. Maybe it's just an 80-column app. The manual doesn't make that clear. So let's try 80-column mode.
Press F1 and... okay, THERE we go! A nice menu of apps. What's available? Some of the best, most-used C128 and C64 utilities. Here's a list:
16K version w/4meg EPROM:
Merlin 128 v1.0
Promos 2.0
My Disk Editor
Function keys
Viza Write 128
Viza Star 128
Seq Reader 128

The 16k version is a melange of C128 and C64 apps, some commercial and some written by Newbury. All are very useful. I can't imagine there's much you'd want to do that isn't covered in here somewhere. But, just to be contrary, I do miss not having a disk cataloger and a simple text editor like ZED.
When you pick a program it comes up in a flash, of course. C64 programs kick into C64 mode and run flawlessly.
The programs have not been modified in any way that I can tell, other than to make them work from the internal ROM. That means when you're done using one of these programs, you have to power cycle your machine to quit. (Newbury's own programs do politely drop you back into BASIC when you exit them.)
No problem, as long as you didn't expect this thing to work like Partner 128, letting you jump back and forth from applications to utilities like Bond from babes to bomb blasts. You can't have everything, dude.
You DID remember to save your program before you hit F1, didn't you?
THE BITS
What other goodies do you get? For twenty bucks? Are you kidding?
Newbury sent me a review package that was complete with a printed manual and a CD-ROM containing the documentation for all of the programs on the EPROM. I doubt you'll get all that for a couple of sawbucks. But I assume he'll be making it all available on the web for free.
Installation instructions are complete and more than adequate to the (very simple) task. The manual includes documentation for all of the utility programs Newbury developed himself. The CD-ROM has PDF manuals and d64 files for all of the commercial apps included.
As stated above, there is, as yet, no documentation on how to create your own EPROMs. But did I mention that it's coming?
THE BOTTOM LINE
Best twenty bucks you ever spent. Ever. Pawn your grandpa's watch and buy this right now. Really. I mean it.
Though I desperately want to create a menu and load it up with my own apps, for twenty bucks what Newbury provides is an excellent selection.
The board couldn't be easier to install. If you can install an internal ROM, you can install this board.
This is a fine product and it solves a basic problem. At least it did for me.
I've already decided to keep the 32K version installed permanently. I had burnt EPROMs for KeyDos, the Servant, and BASIC 8, and have been struggling for a year over which of them to keep in that socket. Now I don't have to choose. Best of all, all three apps are 128-mode programs; I hate having to switch to C64 mode to do anything. Now I don't have to.
Wow :) You couldn't have had better reviews than that, could you? So, Dan, how do I order this marvel? What is the postage for Sweden, Europe?
Wow Mark, I'm speechless. Thank you very much for the nice review!
Now I had better get to work on the 'Do it yourself' manual.
The 32k version adapter that I sent to airship was a modified 16k version. I had to lay out a new board and have ordered half a dozen to play with. They should be here by Friday.
Question, should I put the commercial programs from the 16k version in the 32k version before I send them out?
I did not mention to airship that the printed manual is not included in the package; it was just for his convenience. It costs too much (ink, paper, cover and postage). But, if you want to pay extra for a printed manual, we could work something out. The adapter will come with a CD that has the manual in pdf format and all the other goodies.
QuoteWhen I turn on my C128 in 40-column mode and press F1, nothing happens. At least, nothing happens on my C128.

Maybe it's just an 80-column app. The manual doesn't make that clear. So let's try 80-column mode.
I did find a bug in the adapters after I sent them to airship. It's a hardware problem, not in the software. Sometimes when you power up, the internal ROM will not be on page 0. The F1 function key will not get reprogrammed and you can't get access to the menu. You have to power down and up to make it work. The new 32k board will correct the problem.
QuoteWow You couldn't have had better reviews than that, could you? So, Dan, how do I order this marvel? What is the postage for Sweden, Europe?
To come up with shipping cost, I will need to know your address. I don't need a name until you're ready to order an adapter. If you PM me your address I will find out. I don't mind going to the Post Office, there's this nice to look at......
QuoteBut I assume he'll be making it all available on the web for free.
You can send a copy of the CD to anyone you want, maybe Andrew or Lance will post it.
Airship, I noticed in your review that you didn't mention the other two programs in the ROM; the up arrow and left arrow keys.

You've got two ROMs fighting for control of the same key - apparently the function ROM wins over the Kernal ROM.

Right now the pricing for all four EPROMs are the same, $5.00 USD.
I can buy the EPROMs for just under $5.00 each. If my cost goes up, then I will have to pass on the increase.

QuoteYou've got two ROMs fighting for control of the same key - apparently the function ROM wins over the Kernal ROM.
The Internal ROM adapter will reprogram F1 just before it prints the ready prompt.
If you decide to program you own EPROM, then you can program any one of the 10 function keys to access the menu.
Or you could change the JiffyDos Kernal by swapping F1 with another command you don't use as often. Losing the command to read the directory is for the birds.

The same thing happens with the Servant ROM installed on a JiffyDOS C128. But it's not really that hard to type "@$" and press return, so it doesn't really bother me too much. :)
Maybe we should hack Jiffydos so that it places its "@$" on another F-key? But then again, I wouldn't want to risk getting Maurice all over me for distributing Jiffydos ;)
JiffyDOS no longer exists.
CMD products no longer exist.
They are dead to the CBM community.

At yesterday's SCCAN meeting, we plugged in a Megabit 128 ROM adapter (32K version) into Joe M.'s flat C128 and gave the adapter its first tests. Here are the notes --
1. The 128 ROM adapter board is fairly large and at first could not fit with the JiffyDOS 128
Kernal board plus riser which is to the side. The JD 128 Kernal board plus riser must be
removed. Then the 128 ROM adapter can be easily inserted. The JD 128 Kernal is then
replaced. With a regular CBM kernal ROM in place, a 128 ROM adapter board would fit
more easily.
2. The wire which leads from the C128 ROM adapter to pin 12 of U36 is stiff (hard to lay
flat against the motherboard), though strong and good-looking.
3. No problem engaging the menu with the F1 key.
4. VizaWrite would sometimes crash (break) on start-up, necessitating a system power
down and power up.
5. Pushing the C128's reset switch does not clear the 128 ROM adapter. A complete
cold start would.
6. A surprise... the ZED 128 text editor is included. Another surprise... ZED 128
initializes correctly from the 128 ROM adapter, but when a user tries to type more
than one character into the program, the whole program freezes up.
7. No problem with initializing Maverick's FileCopy or Single Drive Copy modules. The
Maverick other modules have not been tested.

If Maurice Randall is doing a great job pissing everone off (pardon my French), Mr Dan Newbury does the completely opposite thing :)
I received my internal adapter today, only 10 days after I sent the money through PayPal. That time includes packaging of the adapter itself, a very thorough installation instruction and a CD-ROM on which he has printed his own label. Very professional. And then shipping it to Sweden, on the other side of the World. Impressive!
I can't wait to test this device.
If you will ever buy something from Dan, you can do it with a 100% confidence :)

I did some sanding on the right side of the PCB, as much as I dared. But it does not help. The Jiffydos adapter sits up high enough that it will sit over the right side of the Internal ROM adapter PCB. But the edge of the Jiffydos adapter sits against the right edge of the Internal EPROM. It would be prudent to put a strip of insulating tape alone the edge of the Jiffydos adapter to prevent shorting.
Quote2. The wire which leads from the C128 ROM adapter to pin 12 of U36 is stiff (hard to lay flat against the motherboard), though strong and good-looking.
The wire used is a military grade shielded single conductor cable. The shield is to prevent any stray signals from triggering the page switching circuit.
Quote4. VizaWrite would sometimes crash (break) on start-up, necessitating a system power down and power up.
That break out may be the Jiffydos Kernal. My stock 128 does not do that, well, semi-stock 128. I change one byte in the Kernal of all my 128's.
Quote5. Pushing the C128's reset switch does not clear the 128 ROM adapter. A complete cold start would.
There are five programs in the Internal EPROM that require a power down and power up. They are: VizaWrite, VizaStar, Basic 8, Servant and KeyDos. The reason is that the Internal ROM is not set to page 0 when you push the reset button and the F1 function key will not be programmed. During a power up, there is a hardware circuit that assures page 0 will come up every time.
There are two ways to fix the problem.
1. Add another wire from the adapter to the system reset line
2. Add a switch to page 0 routine somewhere in the reset routine in the Kernal.
All the other programs will default to page 0 when you exit the program by pushing the reset button.
Quote6. A surprise... the ZED 128 text editor is included. Another surprise... ZED 128 initializes correctly from the 128 ROM adapter, but when a user tries to type more than one character into the program, the whole program freezes up.
Surprise, you're right, it doesn't work. The program works fine from disk, but when loaded from Internal ROM it crashes.
Here is what I found: When you enter the Internal ROM menu, the pre-configuration registers A & B ($D501 & $D502) are re-programmed in order to access the 32k of data in the Internal ROM. No Kernal or I/O except when you have to switch a page in Internal ROM.
When ZED is selected from the menu, the loader routine will transfer the program from ROM to RAM in the proper location, then jump to start of the program. That part works well, but use another key after start up, it will crash. The program expects the pre-configuration registers to be at their default values.
So, restoring the register values before program startup fixes the problem.
Robert, if you will send me your EPROMs, I will re-program them for you, as well as DLH, airship and SmallCleverDinosaur and I willl send them back to you.
Dan...

Thanks for the advice.

Ooo, military grade... very nice. Joe M. of SCCAN wanted to route the wire between the chips on the board (just as he had done for the JiffyDOS wires), but because of the stiffness of the wire, it had to be held down by electrical tape. It was slightly annoying for him, but it was no big deal for me.
QuoteThat (Vizawrite) break out may be the Jiffydos Kernal. My stock 128 does not do that, well, semi-stock 128.
Ah, we tried Vizawrite with and without JiffyDOS on, but it still would sometimes break.

QuoteOkay, Dan... You've piqued my curiosity... What byte do you change in the Kernal of your 128s?
When I purchased my first 128 back in the 80"s, brought it home, hooked it up and turned it on. Well, isn't this cool, it auto boots the program!
I got tired of it real quick because I turn the 128 on and off quite a bit and push the reset button even more. It made my teeth grit every time the stepper motor would ratchet out to track 1 sector 0 and back again. I could picture myself replacing the stepper motor on the disk drive every 4 or 5 months.
With the help of two books I picked up (128 Internals and Basic 7.0 Internals), I was able to follow the code to the PHOENIX routine that would check the Internal ROM and Cartridge areas and then moves on to the Auto Boot routine.
The PHOENIX routine is called only once in Basic and no where in the Kernal. It turned out to be easy to fix, almost like the software engineers had it in mind to remove the auto boot or leave it in.
After the routine checks the Internal ROM and Cartridge area, it clears the interrupt (CLI) and then checks for an auto boot. What I do is change the CLI to an RTS. It never reaches the auto boot area, instead it will return to Basic where the routine was called. The very next command is JMP $401C, guess what, the next command at $401C is CLI, then it prints the READY prompt.
If you need to auto boot a disk, put a disk in the drive and type BOOT and CR and your drive will ratchet out to track 1 sector 0 to look for an auto boot.
It does not interfere with any program or the operating system that I know of. It's quiet, saves your disk drive and the computer comes up twice as fast.
When I get a 128, that is the first thing I do to it.
QuoteIt sounds like Option 1 would be the way to go. Where on the adapter would you solder that reset wire?
When I finish the 'How to do it Yourself' manual, I will show it as an option on the schematic that will come with the manual. Actually, it's just a wire connected to the board with a direction diode and quickie clip on the other end that goes to the system reset line.
QuoteBTW: do you still take orders for the adapter? I'm very interesting in getting one for my C128D.
I'm putting together 20 units now and will have them finished this weekend. It looks like I will have to make more than 20. There's alot of interest in the adapter.

Exactly what byte is it to change to do this?

QuoteExactly what byte is it to change to do this?
Turn your 128 on and go to the built in monitor.
Enter DFF883 and hit return. This is what you will see:
. FF883 20 CD 02 JSR $02CD
. FF886 CE C0 0A DEC $0AC0
. FF883 10 E2 BPL $F86D
. FF88B 58 CLI
. FF88C A2 08 LDX #$08
. FF88E A9 30 LDA #$30
. FF890 85 BF STA $BF
. FF892 86 BA STX $BA
. FF894 8A TXA
. FF895 20 3D F2 JSR $F23D
The one byte that you want to change is at F88B.
Change CLI to RTS in the binary file that you are going to program in the EPROM.
Dan...
And the dummy with the hex editor that knows nothing about ml code?
CLI=58
RTS=???
Thanks,
dabone
To find out the hex code of RTS (or of any ML op-code), enter the monitor and type
A1300 RTS
Then the monitor will show
A 01300 60 RTS
The "A" is for assemble and that's what just happened. You assembled the op-code RTS into ML. And the monitor responds by showing the hex code for RTS which is 60.
Thanks.

There is one thing you have to keep in mind when you install the Adapter.
Your 128 computer is 20+ years old and the tin plated leads on the IC's have
corrosion on them. So when you connect the clip to pin 12 of U3, move the
clip up and down the lead a couple times to make a good connection.
The same goes for the 28-pin socket.

Good advice. However, in my case, Ray Carlsen removed every chip in my main C128DCR and put in sockets for the ones that had been previously soldered in. Then he re-inserted all the chips. In other words, I now have a fully-socketed C128DCR. So, maybe my C128DCR just has a few years of "corrosion" now. :)

I'm trying to remember the exact circumstances. IIRC, the computer was not coming up with the correct free memory, 80-columns was not working, loading from disk was not working correctly but C64 programs on cart would work. He had it for a long time, trying to debug it. When the easy answers were not found, then he went with chip by chip replacement (hence, all the sockets). He finally traced it to the cartridge expansion port! Two "teeth" in the port were crossed/short-circuiting. He replaced the port, and all the problems were solved.
His and my e-mails about this are

While showing it off at the meeting, I realized that with the word/text processors, spreadsheet, database, and file utilities put into a fully-optioned Megabit ROM Adapter, it would make a C128 a complete business machine right "out of the box". All it needs is a game or two (80-column or 40-column) for when a person is not doing business. :) For instance, those Genie C128 game files at

How have you solved the bank switching between the banks of the EPROM? Using one of the expansion ports I/O areas and a flip-flop IC perhaps?
Would it work with the C128 (in C128 mode)? I.e is the EXROM line directly grounded on the PCB or does it pass through a switch?

Yes.

It does not work in C128 mode. Plug it in and turn on the computer, it will go directly to C64 mode and a menu. From there you can select any one of the programs or go to basic.
Dan...
Have you designed the PCB yourself? If so, why don't you add a switch to the EXROM line (and the GAME line if the cartridge supports 16K ROM-images)?
Then it can be used in C128 mode too with a slightly modified code for the menu :)

The Internal ROM Adapter will work with 128 programs as well as C64 programs and will not tie up the expansion port.
The C64 cartridge will work with 8K programs, 16K programs, single file programs any size that will fit in RAM, multi-file programs if you modify them and it will switch itself off so you can run from the basic prompt.
The only external switch is a system reset to regain control of the cartridge.

Got mine today.
It wasn't what I expected. When I first asked about it it was 16 or 32k version only.
So I open the package, glanced at the directions, popped open the 128 and tossed it in.
(Flat 128 with 64k VDC upgrade)
Imagine my suprise when I press f1 and get 3 pages of selections!
Very nice job.. Great looking product and dead simple to install.
(I put my shield back in, It's a little bowed, but it helps hold the uiec/sd.)
I would ask that you post how to redefine which function key the rom redefines.
(Yeah, I'm running jiffy dos also). It would be nice to put it on either f2 or f8 for me.
Thanks for the cool new upgrade.

I have a new piece of hardware for the 128 Internal ROM Socket. It uses the high capacity EPROMs (27010 1meg, 27020 2meg, 27040 4meg and 27080 8meg).
It comes in a 16k version ($8000 to $BFFF) for a maximum no. of 64 pages or 32k version ($8000 to $FFFF) for a maximum no. of 32 pages.
I need to know if there's an interest for this adapter before I invest anymore time and money on it.
I have a 16k version that has a 4meg EPROM full of programs that I use on my C128 and 128DCR.
Here is a list of the programs:
Merlin 128 v1.0 Promos 2.0
My Disk Editor Function keys
Viza Write 128 Viza Star 128

Maverick File Tracer Maverick Track & Sector Editor
64K VDC RAM Test REU Test
I have a 32k version that has a 1meg EPROM with Key Dos, Servant and Basic 8 installed.

Along with the uIEC, SD2IEC, Behr-Bonz VIC-20 Multicart, Cynthcart v1.2.4, I had the Megabit 128 ROM adapter on display at the Commodore table in the games room of last weekend's Notacon/Blockparty (photos and video to come later). Many attendees were curious about the uIEC and SD2IEC, less for the Behr-Bonz VIC-20 Multicart, and even less so on the Cynthcart and 128 ROM adapter. I gave it my best shot... I tried to explain each device in detail to each attendee who asked.
I had brought all of the C= equipment -- NTSC/PAL flatscreen monitor/t.v. (courtesy of Larry Anderson), 1571 drive, C64 with JiffyDOS, VIC-20 with JiffyDOS, 2 heavy-duty power supplies, 3 boxes of disks, 3 joysticks, one NTSC C64 DTV, and one PAL C64 DTV. One big suitcase was crammed with most of the equipment, barely passing the airline requirements of under 50 pounds. I had to put the rest of the smaller items and cables in my carry-on case and even camera case.
If only I had brought a C128... then I could have properly demonstrated the 128 ROM adapter. Jim Mazurek of the Chicago SWRAP Commodore Computer Club met with me again this year, helped me immensely in gettng the equipment up and running, and even said that if there were Commodore for Notacon/Blockparty next year, he would bring the heavy C= stuff instead of my having to lug the equipment all the way from California!
On the evaluation form for Notacon/Blockparty, in the question for what you'd like to see at the event, I wrote, "More Commodore". :)

Ah, that's good that you figured it out. I was paging through my Basic 8 manual, trying to figure out what your problem was. :)
Time to put the Patech binder back on the shelf,

Just got my hands on one of these, and all I can say is WOW!!!
I now have all the great ROM functionality (plus some great non-ROM apps) I always wanted without any limitations..... ie, Servant always "buggin me" when I didn't need it!
Just resurrecting this thread ... seems all of the posts by Megabit have gone ?!?
Where can you buy these ROM adapters ?
