The micro-KIM is a clone of the KIM-1 created by MOS technologies in 1975 as a development board for the 6502 CPU. The micro-KIM uses many of the same components as the KIM-1 to give it that authentic vintage feel. A total of 5K RAM is onboard with an expansion header for future expansion of memory or add-on boards.

Cameron Kaiser has updated his KIM-1 information page. Besides technical info on this first Commodore computer Cameron also released a KIM-1 emulator that runs on a Commodore C64. This emulator is called the Incredible KIMplement. It is a true, partial emulation of the original KIM-1 hardware featuring: Powered by "6o6" - a full software NMOS 6502 emulation with all addressing modes, simulated ROM, and simulated memory - mapped I/O. LED and keypad emulation via partial RIOT emulation. TTY emulation (ASR-33 subset) via partial RIOT emulation. SST emulation. 4K RAM expander card KIM-4 emulation with 8K RAM expander card (thus total address space 16K).Revision EPROMs built-in, so you don't have to find a pirated set or download them from your own KIM. Load and save RAM dumps to disk.

XLOAD is an easy to use way to transfer data from a DOS-PC to a CBM/PET computer. The computer is connected via a Userport <-> Printerport adapter. At the moment it's a one-way system (PC to CBM/PET) but that will change in newer versions of XLOAD. At the moment the transferrate is about 0.5KB/Sec. The test PC is a AT 486/DX-2 66Mhz.

If you think about a grafix card you might think that's something for the modern PC. But even for the PET series a grafix card was made by the company Eltecthe PET series had a grafix card ad-on. With this card could do a 220 x 256 bitmap on the screen. You can download the whole document and schematics. (German language)
