A Spanish firm developed a 6502 trainer, an SBC inspired by the KIM-1. Hexadecimal keyboard, 6 LED displays, I/O to experiment with. Assembled system, boxed, high quality components like mechanical keys. Aimed at education.

On the Promax MI-650 page you find:

• Introduction to Promax MI-650
• Manuals
• Monitor EPROM images and sources
• Images of MI-650, MI-650B, MI-650C
• MI-650 video demonstrations

Three versions were made:

• MI-650. 6502, 6532 for keyboard/LEDs/audio cassette, 6522 for user I/O, 2×2716 EPROM, 2x2K SRAM. PCB fingers edge connectors for expansion.
• MI-650B. equal to the MI-650, more convenient expansion connectors.
• MI-650C, a redesign, same dimensions and layout, with more modern components, like 65C02 CPU, larger EPROM and 65C22 for keyboard and LED.

All three share the same monitor program, patched for the MI-650C to use the 6522.

Updates for various sources, motivated by the find of Jose Vicente Marques Vidal of four MI-650s and our attempt to make them operational again (missing EPROMS mostly).

I have acquired a Commdore Chessmate! Working well.

Michael Gardi and Stephen Crane are working on Chessmate emulators. Micheal aims for a physical identical one, Stephen uses cheap but powerfull microntrollers.
More on the Chessmate, and the 6530 024 RRIOT (the ROM contains the opening book!) here.

I have added a page on LJ Technical Learning’s Digiac line of 6502 systems.

Sources, manuals, articles, patched binaries for KIM-1 and TIM!Tiny Basic for the KIM-1 and the TIM in the SuperjoltTiny Basic interpreter.

On this page information how to run Tiny Basic, by Tom Pittman, for the KIM-1 or a TIM (RRIOT 6530-004) based machine, like Jolt and Superjolt, with 4K RAM at least extra.Any 6502 machine with character I/O can run Tiny Basic, source is available with just a few changes to be made to I/O, memory layout and breaktest.

All tests and binary file manipulation with Tiny Basic have been done with my KIM-1 and TIM Superjolt simulators, and also got an update this week.
