The KIM-1 family

The KIM-1 is one of the first computer systems build around the 6502 microprocessor, somewhere in 1975.
The hardware and software concepts in the KIM-1 were reused in a number of systems created later.

  • Application and expansion connector
  • KIM-1 monitor software in ROMs 6430-002 and 6430-003
  • RRIOTs in 6530 (equivalent to 6532)
  • Bitbanged serial interface
  • 6 multiplexed seven segment LEDs and hex keyboard
  • MOS Technology papertape format load and save
  • KIM-1 audiotape format

Over the years I have collected a ‘family’ of small computers with one or more concepts of the KIM-1, as shown in the figure above.
