Heh, there is the type-in listing from Compute!'s Gazette at

My BASIC 7.80 offers two color modes for 80-column users.  The first is pure monochrome mode.  All pixels of the bitmap are restricted to one of two colors  -- there are no color cells.  The second is color mode where each 8x8 cell can have it's own definition of colors for the 0 and 1 bits/pixels.  This is equivalent to the VIC/40-Column "high res" mode.  My BASIC 7.80 does not even attempt to emulate VIC/40-Column "multi-color" mode...
That would be a neat trick and only feasible (IMHO) using interlaced video.  In any case, monochrome BASIC 7.80 is available to everybody; the color BASIC 7.80 needs a C128 with a full 64K of VRAM.

Thanks RobertB for the link -- now I have to look into MetaBASIC-128 and VDC BASIC to see how they compare with my BASIC 7.80

VDC BASIC is interesting.  It add commands to BASIC to allow one to access VDC registers or VRAM directly -- no more cryptic POKEs and SYSs.  But as far as I can tell it doesn't do any "high-level" stuff like bitmap graphics.

I could swear I saw a mention -- somewhere -- about a soft-sprite implementation for the VDC.  Does anybody know anything about this?

Microsoft BASIC began in 1975 as the company's very first product: a BASIC interpreter for the Intel 8080, written by Bill Gates and Paul Allen for the Altair 8800. That codebase was soon adapted to run on other 8-bit CPUs, including the MOS 6502, Motorola 6800, and 6809. You can learn more about this time and hear directly from Bill Gates on the Microsoft Learn Website's History of Microsoft video series or by visiting Bill Gates' blog.

The 6502 port was completed in 1976 by Bill Gates and Ric Weiland. In 1977, Commodore licensed it for a flat fee of $25,000, a deal that placed Microsoft BASIC at the heart of Commodore's PET computers and, later, the VIC-20 and Commodore 64. That decision put Microsoft's BASIC at the heart of Commodore's machines and helped millions of new programmers learn by typing:

10 PRINT "HELLO"
20 GOTO 10
This is BASIC M6502 8K VER 1.1, the 6502 BASIC lineage that powered an era of home computing and formed the foundation of Commodore BASIC in the PET, VIC-20, and the legendary Commodore 64. This very source tree also contains adaptations for the Apple II ("Applesoft BASIC"), built from the same core BASIC source. The original headers still read, "BASIC M6502 8K VER 1.1 BY MICRO-SOFT"—a time capsule from 1978.

The version we are releasing here—labeled "1.1"—contains fixes to the garbage collector identified by Commodore and jointly implemented in 1978 by Commodore engineer John Feagans and Bill Gates, when Feagans traveled to Microsoft's Bellevue offices. This is the version that shipped as the PET's "BASIC V2." It even contains a playful Bill Gates Easter egg, hidden in the labels STORDO and STORD0, which Gates himself confirmed in 2010.

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

• BASIC 7.80 (graphics from BASIC now operate on 80-column)

On a side note, the January 2026 of the new Compute!'s Gazette magazine has a review and comparison of several BASIC enhancements for the C64.

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 Encyclopedia
• BASIC 7.80 (graphics from BASIC now operate on 80-column)
• SAM 128 (speech synthesizer)

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]

That's a nice piece of work...very professional-looking.

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.
