The original KIM1 featured a 6502 microprocessor, 1K of static RAM, two 6530 RRIOT IC's, a keypad, and a 6 character 7 segment LED diplay. The Micro-KIM is a suprisingly accurate clone, but features a single 6532 RIOT, 2K EPROM for the monitor program, 5K RAM, and an onboard RS232 serial port, DC input, and expansion bus.
Aart's 6510 cross-assembler, which he
originally developed to relive the good old times of the C64,
is also useful to develop programs for the Micro-KIM, since
it supports, among several other output formats, the paper tape format
that can be directly uploaded and executed on this microcomputer.
Aart is writing a series of tutorials on how to operate and program the Micro-KIM. The tutorials cover many topics ranging from using a cross-assembler to generate programs in paper tape format, uploading and running these on the kit, exploring routines in the monitor program, taking full control of the LED display with custom made characters and even adjusting the brightness, reading the keypad, communicating over the RS232 serial port, and programming interrupt service routines. The series is being published in the Briel Computers Support Forum and on Aart's Blog. Sample source files from the tutorials are given below.
