The Micro-KIM is a single board computer that is closely based on the KIM-1 computer produced by MOS
technology and Commodore in the mid 1970’s. The Micro-KIM retains much of the original design of the KIM-
1 with modifications made to allow extinct components to be replaced with more readily available parts. The
addressing scheme was left intact so all the original programs from the KIM-1 should work on the Micro-KIM.
Many of the programs have been tried but there are still many that haven’t. The Micro-KIM consists of 5K
RAM, 2K EPROM, a 6532 RIOT for I/O, a 23 key keyboard and a 6 digit display. The added features include a
simple DC in feature for using a single source power supply such as a wall wart; a RS232 adapter for use with
the monitor terminal program, and a 40 pin expansion header for future expansion.
