https://www.ebay.it/itm/376241376516

NEW C128 RGBi adapter to VGA!

Connect your C128 RGBi port to VGA monitor (15KHz horizontal freq. compatible!)

The anchoring screws for the C128 are present, as well as those for screwing for the VGA cable!

Just simply select the option that you want:

TYPE 1 --> 8-color 80-Column RGB

This adapter version is used to connect the rear 9-pin RGBI port on the Commodore 128 to a 15-pin VGA cable which then connects to a 15-kHz capable VGA monitor.
This gives you 8-color output and 80-Columns (double the 40-columns of the VIC-II chip) of text using the VDC Chip inside the 128.

TYPE 2 --> 16-color 80-Column RGB
This adapter version is used to connect the rear 9-pin RGBI port on the Commodore 128 to a 15-pin VGA cable which then connects to a 15-kHz capable VGA monitor.
This gives you 16-color output and 80-Columns (double the 40-columns of the VIC-II chip) of text using the VDC Chip inside the 128.

TYPE 3 --> 16-color 80-Column RGB + VLR (with USB power cable 1mt)
This adapter version is used to connect the rear 9-pin RGBI port on the Commodore 128 to a 15-pin VGA cable which then connects to a 15-kHz capable VGA monitor.This gives you 16-color output and 80-Columns with a PERFECT IMAGE because is equipped with VLR!
It is equipped internally with active VLR circuit. Power cable cord is included (USB connector 1mt) and you have to connect to standard AC/DC adapter (like smartphone)
This gives you 16-color output and 80-Columns with a PERFECT IMAGE because is equipped with VLR!
These vertical bars are visible especially in VGA mode on the first ASSY versions of the 128. The advice is that if you have already connected your c128 in 80 columns and you have these vertical bars on the VGA monitor then with this version you will notice an incredible improvement

PLEASE REMEMBER THAT:

This ADAPTER requires a VGA monitor that can sync to a 15-kHz signal. Normally, VGA uses a horizontal frequency of 31.5kHz. But, the Commodore 128 basically outputs a CGA signal which is a 15-kHz digital RGBI standard. It's this standard of the Commodore 128!
In any case there are some modern VGA monitors capable of displaying 15-kHz (Acer, Dell, Asus, BenQ, etc. etc).

ugBASIC 1.17.2 Released

A new version of ugBASIC, the open source isomorphic BASIC compiler, has been released.
In addition to making some specific commands, such as DRAW and PLAY, compatible with multitasking, support for custom data types has been added at the language level via the BEGIN TYPE statement. The compiler has also been improved and optimized for Commodore 64, Commodore 64 REU and Commodore 128 computers.
ugBASIC is a cross compiler for Linux and Windows, for writing games in the BASIC language, running on dozens of different home computers and 8-bit consoles. There is also a convenient integrated IDE for Microsoft Windows and even a sandbox, if you don't want to install anything.

From Thomas Lövskog
 
Today I got the new revision of my VIC NX* board soldered. It is now ready for hooking up to the logic analyser, oscilloscopes and start testing. Hopefully we can get this booting to the Ready prompt. The characters will be totally garbled though. The character ROM in this variant resides in SRAM and needs to be initialized. For that we need some code. Code that is executed in a hidden partition of the 512k for BLK6/7 before anything else. This is also where configuration firmware will reside.

Smoke test is done. All regulators work as expected, there is 5V where it should and Meatloaf is booting. The GreenPAK (little sub board in the top right corner. It will be soldered down as a tssop20 in the next run) manages the power, top LED and reset as expected.

However. To much work this weekend so it will have to be in this state until next week(end).

* VIC NX is my idea of an enhanced reproduction of the famous VIC 20. It is built on the 6502, 6522 and 6560/61 in DIP and the rest is modern of the shelf parts. Fully expanded and some extra features. See https://blog.lskg.io/tag/vic-nx/
The FATVIC, drop in replacement for 6560/61 is also shown here. This will be a nice test vehicle for that project.

In development - a new game for the C128's VDC

https://goodwell.itch.io/crawl128

Hardware Requirements
This game is designed to run on the Commodore 128 (yes, in C128 mode), and is using the VDC-Chip (not the VIC-II chip, which is used in C64 mode). Also, the VDC-Chip needs to have 64kB of VRAM available.

When I moved the forums from the temp site to the hosted site I neglected to update a few settings - this resulted in some broken links - I've fixed most, will audit the board over the weekend to ensure that all links are correct again.

Also, my Stop Forum Spam API key wasn't added in to the board - this has now been corrected as well.

FATVIC is a drop in replacement for the 6560/6561 VIC chip used in the Commodore VIC 20 computer. It has all the usuall features of the 6560/6561, but also some extra optional features. Full memory in BLK0 accessable by the VIC chip, VGA mode, and enhanced functionallity with 32 sprites, hires graphics and fast hardware accelerated drawing and memory copying.

Most Commodore BASIC interpreters have a bug in the floating point multiply routine. The bug can be demonstrated with the attached BASIC program and also one that will correct the bug.

A new version of ugBASIC, the open source isomorphic BASIC compiler, has been released.

This version for Commodore 128 supports improved multiplexed sprites, synchronized vertical blank at line level, native "SID" audio files, and virtual console text scrolling. 

Moreover, the language integrates many Simons' BASIC instructions.

ugBASIC is a cross compiler for Linux and Windows, for writing simple language games, that can run on dozens of different home computers, and 8-bit consoles. 

There is also a convenient built-in IDE for Microsoft Windows, and even a sandbox, if you don't want to install anything at all.

Our books, data sheets, manuals etc library is back online (I had forgotten about these!)

You can reach it at https://www.commodore-128.org/Library/

I have a few more items to upload it, but there's roughly 350 items in it so far.

I'll also add a direct link (via a menu button) on the top of the forums a tad later.

Frank Eggen's Switchless 8x Multi-Floppy Speeder 32KB RAM extension (DolphinDos 3) for the C128DCR and the internal 1571 floppy drive has been released on Github. Documentation, schematics, Gerber files, Kernal ROMs and logic files are available there. So everyone can rebuild this project.

This project is a further development of the very fast and popular DolphinDos3 for the C128 and the 1571 floppy disk drive. It uses the best of the retro world and the technology of the present and has never been available before. Switchless 8x Multi-Floppy-Speeder not only runs with DolphinDos 3 but can also run up to 8x DOS Kernals and C128/C64 Kernals and can be conveniently activated via DOS commands. This means that JiffyDOS 128, for example, can also be run alongside the original CBM-Dos and DolphinDos 3. This ensures maximum compatibility. The 32KB RAM extension is organized in 4x 8KB banks and, together with the Peripheral Interface Adapter (PIA, type 6821 or 6521), enables ultra-fast parallel data transfer and control of the 4x 8K RAM banks (32KB).

The Switchless 8x Multi-Floppy Speeder with 32 KB RAM extension for the Commodore C128DCR is one of the universally applicable accelerators for the internal 1571 floppy disk drive of the C128DCR.

In addition, the "Switchless 8x Multi-Floppy Speeder" is fully RAMBoard-compatible, which enables the use of corresponding nibble copy programs that support RAMBoard.

All going well this Staurday I'll attempt to move the site to the commodore-128.org domain.

Fingers crossed

There will be an outage between midnight and 6am (Australian Eastern Summer Time) on Wednesday 27th of November while the NBN connection is being upgraded.

From the homepage at https://github.com/idun-project/idun-cartridge

This is the home of the idun-cartridge for the C128. Here you will find the latest software, along with source code, sample applications, and other content.

What does it do? Hopefully a demo is worth a thousand words. 

Hardware
The idun-cartridge uses a Propeller 1 micro-controller to provide a fast hardware interface between the C128 and a Raspberry Pi ("RPi") that runs a customized Linux OS. The cartridge is designed to work and fit best with the Raspberry Pi Zero 2. However, any recent Raspberry Pi can be made to work.

The first set of photos show the idun-cartridge with RPi Zero 2 fitted. As you can see, a standard-sized C64/128 cartridge case can be hacked to cover the board, but leave the RPi, ports, and button accessible.

Partial Support for original Pi Zero
The original Pi Zero is nearing end-of-life, being phased out by the Raspberry Pi Foundation in favor of the more powerful Pi Zero 2. Because of this, some ARM Linux disributions are discontinuing support, making it difficult for the idun-cartridge to continue supporting the Pi Zero. However, the current state of affairs is that the Pi Zero is widely available and very inexpensive, and this could remain the case for the next year-or-so.

In light of the above, the Pi Zero is partially supported. You can download a compatible image file that includes v1.2 of the software. All features are present on this image except for the idunSID remote SID player software (it requires a newer glibc library) and the Z80 programming support.

There will be scheduled down time on the 25th of November from 8am - 12 noon (Australian Eastern Summer Time) to replace a mechanical hard drive in the server with an SSD.

Later on this month the forums will move directly to https://www.commodore-128.org and away from the this temporary site.

Once I have the exact date I'll give a few days notice - the changeover should be seamless; all of my testing has been good so far with only a couple of small issues that had to be worked out.

The swap should take an hour or two at most.

Ward Christensen has died. He was the co-creator and SysOp of the first BBS to ever go online, and the creator of the XMODEM file transfer protocol.

Alpha King was kind enough to write up this tribute:

"Today, we say goodbye to a true pioneer and legend in our community, Ward Christensen. As the co-creator of the first public Bulletin Board System (BBS), Ward laid the foundation for what would become a thriving network of communication and collaboration long before the modern internet.
Through CBBS, Ward and Randy Suess gave us a space to connect, share knowledge, and build communities that transcended physical boundaries. For those of us who lived in the BBS scene, it was more than a platform—it was a culture. Whether we were sharing files, chatting in message boards, or exploring the corners of digital freedom, Ward's contributions made it possible.
Ward's vision and ingenuity shaped a movement that influenced so much of what we do today, and his spirit of innovation will continue to inspire future generations of builders and dreamers.
Rest in peace, Ward. Your legacy will live on in the code, the communities, and the memories we all share."

Yes - there is such a thing - https://www.spritemate.com/

Collection of Basic games from the book BASIC Computer Games, published by Creative Computing.

Most of these are very simple and should easily run unmodified on the C128 (or expanded for it).

Our classic mid 1980s BBS in now online - it's running under BBS-PC! 4.20 and is fairly basic, but it's really up for nostalgia purposes.

You can either telnet ( at telnet://landover.ddns.net:23 ) to it using a comms program or access it via the web on our main page at https://commodore-128.org

In keeping with the theme of the site it has CBM 8 bit messages areas.

NOTE - 80 column ANSI only!

Enjoy

We now have a Discord server - invite - https://discord.gg/Wv9BDynr

Under development at the moment (so I'll guess we need to keep an eye on it at the moment) is the Checkmate 19"  (also 17") IPS Retro Monitor (aka A1500 Plus).

Also - it makes specific mention of the C128 - so there's that!




Info at Checkmate A1500 Plus

The forums and FTP site will be offline on Friday 4th October between 8.30am and 3.30pm (Australian Eastern Standard Time) for maintenance (power supply upgrade).

It will likely be a shorter period - just setting expectations.

Version 1.16.4 of ugBASIC and UGBASIC-IDE has just been released that supports the C128.

Targets : Windows (32 & 64 bit) and Linux (32 and 64 bit)

The compiler can produce executable files in "prg" format and entire "d64" disks, including files that can be loaded using the language's primitives.

CP/M ON THE C128 (ARTICLE 1)

by Noel Nyman

(Copyright 1986 by Geoduck Developmental Systems. Permission
to reprint this material is hereby granted, provided this
notice is included in the reprinted material.)

In this column we plan to explore CP/M (Control Program for
Microcomputers) and how to use it on the C128.  A special
INPUT CP/M1 disk is also available with the latest CP/M
operating system, several programs, and reprints of these
columns (see the disk order form elsewhere in this issue).

To understand the what and why of CP/M, we have to go back
to the early days of microcomputing.  In this primitive time
there were mainframes, huge and expensive computers.
Communicating with one required a "console" which had a
keyboard and an output device.  The output was frequently a
printer, although the cathode ray tube (CRT or tv screen)
was becoming more common. Refurbished teletype machines were
often used as consoles.

In the early 1970's a revolution began that would change the
course of computing...the LSI (Large Scale Integration)
micro chip.  It became possible to produce on a single piece
of silicon all the logic in CPU's (Central Processing Units)
requiring several circuit boards on the mainframes.  The
first popular microprocessor chip, the 8080 designed by
Intel, was used to make intelligent terminals.  These were
consoles that contained a keyboard and CRT monitor, a small
amount of RAM (Random Access Memory) and some means of
communicating with a mainframe.

The large hard disks and tape drives used by the main frames
were too complex for a microcomputer to control (there
wasn't enough RAM to hold the controller program required).
So the micros used paper tape. A punch poked rows of up to
seven holes in the half-inch wide tape, each hole
representing a bit in a seven bit character or command.  A
paper tape reader translated these holes into binary data to
store in the micro.  Storing a program was noisy and slow.

In 1973 IBM developed the first floppy disks as alternatives
to the then popular punch cards used on mainframes.  Gary
Kildall at Intel obtained a used drive from a small company
named Shugart and began working on a controller program to
interface it with an 8080 based microcomputer.  He and John
Torode developed the controller into a full disk drive
operating system, which they called CP/M.  Intel wasn't much
interested in the project, and Kildall and Torode began
marketing the product on their own through Digital Research
in 1976. The rest, as they say, is history.

CP/M is an operating system.  Every computer needs an
operating system in order to interface with the console, the
disk drives, and any other peripherals such as modems and
printers.  In the relatively advanced age we live in, home
computers usually come with their operating systems in ROM
(Read Only Memory). When you power up your C128, it "knows"
how to talk to the keyboard, screen, etc.  The Commodore
disk drives have their operating systems in ROM also.  You
don't need to LOAD any program in order to type on the
keyboard, print characters on the screen, or find a file on
a floppy disk.

In 1973 computers were much less smart. Partly this was due
to the high costs of both RAM and ROM. A 32K machine cost in
excess of $3000 without peripherals (1973 dollars, gasoline
was still under $0.20 a litre then).  ROM was very expensive
and difficult to program, EPROM's (Erasable Programmable
Read Only Memory) weren't available.

Each time you turned the power on, you had to teach the
computer how to be a computer all over again.  You did that
by writing a program called the operating system, and
SAVEing on disk or paper tape.  You used another smaller
program that often was typed in by hand each time to LOAD
the larger program.  This method of using a program to LOAD
other programs was called "bootstrapping" since the
computer was in a sense lifting itself by its own
bootstraps.  The idea of "BOOTing" an operating system
remains with us, and is a command recognized by Basic 7.0.

CP/M provided a standardized operating environment on many
different computers.  For example, the TRS-80 machines use
the command LPRINT to send strings to a printer.  Commodore
uses PRINT# followed by a file number. But any printer
routine written on a machine running under CP/M will run on
any other CP/M machine (I'm not sure why "running under" is
used, but that's the proper term).

CP/M comes in four main sections.  The first is the LOADing
routine, which is usually on reserved tracks on CP/M disks.
On the C128, the LOADer is found in ROM.  The two workhorses
of CP/M are the BDOS (Basic Disk Operating System) and the
BIOS (Basic Input-Output System).  Note that the term
"Basic" as used here is a synonym for "primary" or
"essential" and does not refer to the BASIC programming
language.

The BDOS is identical for all CP/M systems of the same
version.  BDOS works much like the Kernal jump table in
Commodore machines, providing access to the routines for
opening disk files, printing strings, and such by simply
calling them by number.  The BIOS is customized for each
computer model.  When the BDOS is asked to open a file, it
uses several BIOS routines which are customized for the disk
drives, data buss structure, etc.

The last section is a program call CCP (Console Command
Processor).  The CCP accepts input from the keyboard,
displays it on the screen, and places it in memory where
appropriate for execution by other programs.  On most
systems the CCP must be reLOADed after other programs finish
execution.  On the C128, the CCP is always resident.

There have been several versions of CP/M produced since
1973.  The C128 runs under CP/M 3.0 (sometimes called
CP/M+).  This is the most advanced CP/M available, used
computers with bank switching capability and over 64K of RAM
can use it.

If you'd like to read more about CP/M, there are many books
available.  Since it's a relatively old system, your library
may be a good source of information.  Try to get material
for CP/M+, since some commands for older CP/M versions are
different.  Some good references are:

THE CP/M PLUS HANDBOOK, Alan R. Miller, Sybex

CP/M AND THE PERSONAL COMPUTER, Dwyer & Critchfield,
Addison-Wesley

If the date on the screen when you BOOT CP/M is older than
December 4, 1985, you should get a copy of the new operating
system.  This is available from CompuServe, Q-Link, the
INPUT CP/M1 disk, or perhaps a user in your area has one.

----Some additional references----

DR DOBB'S JOURNAL, especially earlier issues, covers CP/M
extensively, you local library may have past issues
available.  For an interesting article by Gary Kildall on
the start of CP/M, see the January 1980 issue.

Old copies of BYTE, KILOBAUD MICROCOMPUTING, and INTERFACE
AGE also have articles on CP/M.  For a series on CP/M+,
check the February 1983 issue of MICROSYSTEMS.

Two CP/M user groups have disks available with a variety of
programs.  The 1571 drive will read KayPro IV format.  For

Vision BASIC v1.1 - Much faster compile times on C128 in C64 mode - BASIC programming.
Here's what the developer provides as the list of new features in Vision BASIC v1.1: https://visionbasic.net/vision-basic-1-1-has-arrived/

What's new:

Support for GeoRAM as an alternative to REU, for the expanded RAM required to run Vision BASIC.

Support for battery-backed GeoRAM variants (e.g. NeoRAM) to store a copy of C64 RAM, enabling instant access to Vision BASIC and loaded programs at all times.

New commands in the add-on pack for accessing GeoRAM memory in your own programs.

Custom NeoRAM cartridge available for purchase as part of a Vision BASIC package.

Improved default Vision BASIC editor colors.

Compile speed doubled when compiling on a C64.

Compile speed quadrupled when compiling on a C128 in C64 mode.

New commands: GSAVE, CATCH, ALLMOBS, DEF, POLL, LABEL.

Existing commands improved: LISTER, BLANK, NORMAL, VIDLOC, PANX, PANY, PADDLE, VERSION, RND, RANDOM, BYTES.

New format for user-defined commands to improve assembly language programming.

Asterisk (*) now allowed for declaration of assembly program starting address.

System clock no longer resets during program compilation.

Filename length now restricted to 12 characters during program compilation to disk, allowing proper appending of file extension.

SHIFT - RUN/STOP key combination no longer causes potential data loss.

Overflow of variable information in designated RAM space is now detected.

RUN/STOP - RESTORE delay implemented to avoid accidental exit out of Vision BASIC editor.

Improved startup experience for PAL users unable to use the on-disk fast loader program.

Variable names can now be of unlimited length, provided everything fits on a single program line.

Vision BASIC manual now includes a command index.

BUTTON command now supports the programming of 2-button and 3-button game controllers - e.g. joysticks, gamepads.

Added to the Downloads area ( geos-ramboot-v1.1.zip)

RAMboot v1.1 by Spike Dethman with additional credit to Joseph Thomas for the Drive RESCUE concept (Dated March 18th, 1993) - RAMboot is a GEOS 64 / 128 (40 & 80 column mode) Auto Exec that replaces the REU quick reboot with one that restores your disk drives to their proper locations, re-executes any Auto Exec files on the current disk and re-enters GEOS.  Requies a 1750, 1764 or clone RAM expansion.  Full documentation is on the disk.

C128 GEOS files have been restored in the Downloads area.

Vice 3.8 was released in December '23 (been a while since an update has been announced here )

https://vice-emu.sourceforge.io/index.html#download

* Changes in Vice 3.8
=====================

** general
----------

- added WIC64 support for C64,C128,SCPU64,VIC20
- virtual device (host directory) fixes (Scratch command correctly returns
  number of scratched files, Rename command produces "file exists" error if the
  destination file exists)
- added video capture in ZMBV format. This will produce lossless videos at correct
  emulated FPS.
- the old FFMPEG support was deprecated and is disabled by default. New experimental
  code was added that will work with external ffmpeg executable instead.
- reSID: fixed a Noise Init problem
- reSID: filter tweaks
- reSID: The 6581 saw+pulse waveform was wrong
- reSID: tweak shift register reset time for 6581
- reSID: 8580 Filter ringing fix
- reSID: 6581 filters: allow negative values for kVg-Vx
- made raw printer driver pass through all bytes 1:1
- Tape: changed default zero-gap delay from the rather weird (and way too large)
  value 20000 to the more sane 2500 which MTAP uses
- RS232: handle RI line in IP232 (requires updated tcpser, see
  ​https://github.com/go4retro/tcpser/pull/24.
  - Add option to invert the RI line. This should help to make some more obscure
    BBS programs work
- RS232: removed undocumented feature to use unix domain sockets when the first
  character of a rs232 device is a pipe character, and instead used pipes, like
  it will be done on windows too
- Drives: fixed 1571CR emulation
- Drives: allow up to 83 tracks for 3.5inch mechs
- Drives: fixed clock rollover in rotation code
- REU: fixed DMA access to C64 RAM at $00/$01
- Added PaperclipE, PaperclipSC, and Paperclip2 dongle support.
- Added woj userport joystick adapter emulation.
- provide fake sid hooks so hardsid can be used when fastsid is disabled
- Printer: new reworked emulation handles various CBM Printers: 2022, 4023, 8023,
  MPS801, MPS801, MPS803
- Printer: tweaked MPS page height, now allows print shop to print a greetings
  card on a single page.
- Printer: do not produce any output for non-printable codes
- Printer: when using the graphic output driver, only produce a new file when
  actually doing a formfeed.
- Build the list of available palette files at runtime, scan system path/dirs as
  needed. Also read extra info from the .vpl files. New palettes can now be just
  dropped into the data dir and they will appear in the UIs.
- allow color controls to be used with external palette and when no crt emulation
  is active.
- Added more realistic vicii color ram init code.
- CIA: shiftregister fixes
- CIA: fixed ICR timing/behaviour (This fixes the dd0dtest from the testbench)
- Support for ISA/PCI devices that were accessed via direct I/O was removed,
  since this would not work in any sane modern OS anymore. The affected devices
  are: parsid (windows), ssi2001 (all)
- Z80: OUT, OUTD, OUTI, OTIR, OTDR instruction fixes
- Fixed -initbreak reset so that the first instruction doesn't run


** Buildsystem
--------------

- add configure switch `--enable-experimental-devices` to enable experimental
  emulation of some devices.
- changed configure switch `--with-libcurl` to `--without-libcurl`.
- changed configure switch `--enable-lame` to `--with-lame`
- changed configure switch `--enable-libieee1284` to `--with-libieee1284`
- changed configure switch `--enable-portaudio` to `--with-portaudio`
- configure: change `--with-zip-bin` to `--with-unzip-bin`
- remove the configure switch --with-readline/--without-readline.

- Do not build PDF docs unless --enable-pdf-docs
- Fixed macOS bindist. Probably doesn't work without code signing, however an
  attempt is now made to detect and use a signing identity.
- when installing with x64 not enabled, install a symlink x64->x64sc instead
- Add unzip.exe and its deps to Gtk3 bindist
