Looks like Vice 2.3 is released,  can be gotten here

http://vice-emu.sourceforge.net/

Many thanks to the vice crew for releaseing this and for all their hard work

sorry about that,  heres a link to a complete 128 diagram,  info for the power supply within includeing part numers and layout and values,  hope this helps.

you should check the main tranisistor on the heatsink,  its probalble shorted,  start there.

Here`s a link to a external power supply for the 128,  this will help a little.

very interesting,  thanks

Thanks BDD there for an excellent explantion of POLL and PHONIX rountines.

A long time ago I messed around with this problem in vice and found this in the basichi rom (swap command)


monitor
    pc  sr ac xr yr sp
; fb000 00 00 00 00 f9
d faa53
. faa53  e0 10    cpx #$10
. faa55  b0 0e    bcs $aa65
. faa57  20 45 a8 jsr $a845
. faa5a  8e 06 df stx $df06
. faa5d  68       pla
. faa5e  a8       tay
. faa5f  ae d5 03 ldx $03d5
. faa62  4c 50 ff jmp $ff50
. faa65  4c 28 7d jmp $7d28

the above checks to see if the bank is bigger than 15 if so it prints an error message

using monitor command type f aa53 and you will see above in rom, the easy way of fixing this is to burn another rom and insert it with ea in aa53 such as below



monitor
    pc  sr ac xr yr sp
; fb000 00 00 00 00 f9
d faa53
. faa53  ea       nop
. faa54  ea       nop
. faa55  ea       nop
. faa56  ea       nop
. faa57  20 45 a8 jsr $a845
. faa5a  8e 06 df stx $df06
. faa5d  68       pla
. faa5e  a8       tay
. faa5f  ae d5 03 ldx $03d5
. faa62  4c 50 ff jmp $ff50
. faa65  4c 28 7d jmp $7d28


my solution was to just add ea`s (nop) ( no operation) to the 4 spots and it works fine, else you could write your own code and then jump to aa57

might be other ways of doing this but i found this the easy way out and it works

I have a option of what the sysgen is,  but would like to hear an explantion of what it does from other members,  thanks.

seems i remember that the simm`s have to be a type called "fast page" and that the type "edo" wasnt really compatible for memory, seems i remember reading this somewhere.

Small, compact and effiencent, and looks like very easy to use, gonna have to get a couple of these for sure.

I tryed your code in vice and had to modify it to this to keep from getting errors

w=(dec("cdcc")):bank15

sysw,64,4:sysw,50,6:sysw,56,7:sysw,3,8

good luck with display

I was looking for some datasheets the other day on this website http://www.alldatasheet.com/  and found some interesting info that I would like to share concerning a possiable 80 rgb to  ntsc/pal convertor.

http://www.analog.com/static/imported-files/Data_Sheets/AD725.pdf

Please download pdf to look at, and you will see that it takes the rgb output from the c128 and turns it into a composite video signal.

Mainly look at page 12 of the pdf file to see the proposed rgb circuit.

Also this takesthe rgb and puts it together and then puts it on a color subcarrier and then through timing adds it to the monocrome video signal coming out of the 128 rgb port together into a composite video signal, much like the 40 col video signal coming out presently, and it will work depending on the crystal you use, ntsc or pal.

I did more checking at the digikey website http://www.digikey.com/  and found that the ad725 is still being made along with the nessicary crystals and othe nessicary part needed to build this circuit.


Mine you I havent made one of thede circuits yet but thought I would put the info out there to see what other think about such a project, if if anyone is interested in getting it working and perhaps mass marketing it to others

found those turicane games here along with many others, may want to check this webpage also

http://www.c64.com/

click on games then select the letter t then go down the list section, all in order

here is a article on how to do it properly  http://alanger.net/comm/misc/big_page.html  , you must cut a circuit wire trace and insert a switch to diable drive, and then turn it on to enable the drive, but you may just want to change the drive number to alieveate your problem.

the product works, its the software for the pc that needs upgrading.

please remember the guy that made this product only had a 64 to work with, had he had a 128, he would have improved the software.

also the fast serial routines are sent from the 128, when they are not acnoligize, then the 128 switch to the slow serial mode, so it dont matter how the fsdir pin in the 128 is set, so to say......

first you gonna need a schematic of the computer which can be found here (use the 310378 series for the flat 128 series) http://www.zimmers.net/anonftp/pub/cbm/schematics/computers/c128/index.html

next check the fuse make sure it`s still good, then check with your multimeter the power supply and make sure it`s still working the 5 volts and the 9 volts respectively

hopes this helps

yes i have one, its works good in the 64 mode, but doesnt work in the 128 mode due to the 128 trying to use the fast serial routines, but a fix in the pc progrogram would fix this.

basically it sends data to the pc and then sends data back to the device and then buffers it and then syncs it to the clock and then sends it to the commodore computer.

overall its a good pruduct, just needs better pc program support
