Ah-ha!  By looking at https://telarity.com/~dan/cbm/languages.html , I also see MetaBASIC-128 and VDC BASIC, both for the C128.

Hmm, how many were there for the C128?  :)
Other than BASIC 8, I can't think of any.

Quote from: Hydrophilic on January 17, 2026, 01:51 PMI'm glad to see Commodore 128 Alive! again.  On a related note, I just got my website up and running again.  No forums, but some things the C128'er might find interesting are:

BASIC 7.80 looks interesting.  A couple of notes:

  • "Multi-color bitmap modes. The VDC can not display 4 colors in a single cell. You might be able to emulate this with interlace mode."
  I recall BASIC 8 used dithering to simulate multi-color.  Might be a possibility here, although likely complicated to implement.  
  • "Split-screen modes.  The VDC does not have a raster interrupt.  Should be possible with synchronized CIA interrupt."
   The problem with doing that is CIA timers are run by the ~1 MHz I/O clock, which cannot be evenly divided  to match either of the two possible VDC scan rates.  So it would not be possible to generate evenly-spaced timer IRQs that follow the VDC scan rate.  You'd have to configure the VIC to raster interrupt at the desired time, as well as the usual time, and wedge into the IRQ handler to trap the mid-screen interrupt.  That, however, poses a synchronization issue, since the VDC dot clock is not related to the VIC's clock.  While I may be wrong, I'm not seeing a workable solution for this.[/list]

128 programmers / Automatic Proofreader v3.0
Last post by RobertB - January 21, 2026, 06:20 PM
In the January 2026 issue of the new Compute!'s Gazette magazine, Automatic Proofreader v3.0 was released as a type-in program.  Consisting of about 60 lines in BASIC 2.0, v3.0 "is a universal tool, intelligently detecting whether you are typing on a Commodore 64, VIC-20, C128, or Plus/4.  It seamlessly hooks into the operating system to provide real-time checksums for every line of BASIC you enter, using a version of the tried-and-true algorithm from the February 1986 version."

Automatic Proofreader will now be able to help those programmers who are typing in the Commodore type-in listings from the magazine.

The Coyote Electronics pin configuration is also called "PET User port adapter" in the VICE emulator, so it is expected to be wide spread. Space Invader + is the completed pin configuration of the previously mentioned games and can also be found on the "stupid PET tricks" adapter.

I have the older Stupid PET Tricks adapter, but I didn't know about the Zimmers' list of PET joystick games.

Thanks!

PET hardware / PET Joystick Adapter
Last post by Blacklord - January 20, 2026, 06:25 AM
Sven Petersen has released a new piece of hardware for the PET.

A C64/VIC-20/Atari Joystick Adapter for the Commodore PET. It supports the Coyote Electronics pin configuration (two joysticks) and the space invader/break put style pin configuration (left, right, fire), found on zimmers.net (https://www.zimmers.net/anonftp/pub/cbm/pet/games/english/joy/index.html).

The Coyote Electronics pin configuration is also called "PET User port adapter" in the VICE emulator, so it is expected to be wide spread. Space Invader + is the completed pin configuration of the previously mentioned games and can also be found on the "stupid PET tricks" adapter. Hence the name. All joystick games found in the previously mention source could be played with this joystick adapter.
