Quote from: luvtofish on September 18, 2025, 04:08 AMI know this thread is a few months old. But are the download links also broken? I'm trying to download Blitz128 compiler and getting a 404?

Yes - I've got that on the list of things that need redoing.

    I recently revisited the HomeComputerMuseum in Helmond, the Netherlands, and found the Commodore and Amiga treasures better organized and better displayed than ever before!  At the following links, you can find my photos taken at the museum.

    Google puts a limit on how many photos you can display per posting, so my pics are divided into 7 parts.

Join us and the tens of thousands attendees at the Sept. 26-28 Bay Area Maker Faire in Vallejo, California!

https://bayarea.makerfaire.com

Our booth is called the Classic Bay Area Computers! (CBAC!). I've decided to bring the Ultimate 64 with all kinds of new/old games or Commodore 128 with TeensyROM 64/128, the Amiga 1000 with Firebird accelerator or Amiga 500 with Wicher accelerator, the AmigaOne A1222+, and a Toshiba T3200SX giant laptop! My other friends will be bringing in their machines, anywhere from Tandy's to Mac's to rare Japanese computers and/or game consoles.

Though location not confirmed yet, we'll probably be in one of the Coal Shed exhibit buildings. We'll be setting up on Thursday afternoon, and then the BAMF attendees will pour in on Friday, Sept. 26. It will be a long weekend!

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."

The announcement from Microsoft is here and the code is here.

Supported Computer Systems

The source code includes conditional compilation support for multiple pioneering computer systems:

Apple II (REALIO=4)
Commodore PET (REALIO=3)
Ohio Scientific (OSI) (REALIO=2)
MOS Technology KIM-1 (REALIO=1)
PDP-10 Simulation (REALIO=0)

Technical Specifications

Language: 6502 Assembly Language
Target Processor: MOS Technology 6502 8-bit microprocessor
Memory Footprint: 8KB ROM version
Features: Complete BASIC interpreter with floating-point arithmetic
Architecture: Designed for both ROM and RAM configurations
Key Features
Programming Language Support

Development History

The source code includes detailed revision history showing active development:

July 27, 1978: Fixed critical bugs in FOR loop variable handling and statement parsing
July 1, 1978: Memory optimization and garbage collection improvements
March 9, 1978: Enhanced string function capabilities
February 25, 1978: Input flag corrections and numeric precision improvements
February 11, 1978: Reserved word parsing enhancements
January 24, 1978: User-defined function improvements

Kingston University had an 8-day show featuring retro computers and game machines from 1977 to 1993.  Included were Commodores and an Amiga.  To see the walk-through video, go to

In the past, C= repair tech Ray Carlsen sold a ribbon-type cable to replace an SX-64 keyboard cable. Now he sells replica SX-64 cables which are a close match to the original ones! To see both cables for sale, go to
