Compute II
Compute II was a short lived split-off of Compute! and also a continuation of the KIM-1/6502 User Notes. Three issues and it was merged back with Compute! again.
Selected articles on KIM-1, AIM 65 and SYM-1 and 6502 in general

n 1975 MOS Technology started delivery of 65XX ICs. So 2025 marks the 50 year anniversary of the 6502!
The earliest mentions of the KIM-1 are from January 1976. The date of the first edition of the User Manual, and first mentions in e.g. Byte.
So I propose to declare January 2026 as the 50th birthday of the KIM-1!
#50yearsKIM1
When I acquired a KIM-1 Rev A, obviously sold by NCE/Compumart, it came with some documentation that may interest any programmer working with the MOS Technology (R)RIOT 6530 and 6532.
The timer description the datasheet is a bit vague about how to use. What may help is the document ‘KIM-1 Application Note 2 Interval Timer Operation’ by MOS Technology.
A document with listings of KIM-1 programs called ‘KIM-1 Application Programs CT1’ illustrate the usage of the timer in interrupt mode. You find the documents here:
Compumart KIM-1 Rev A – Retro Computing
When I acquired a KIM-1 Rev A it came with some documentation revealing its provenance:
- Warranty card
- Brochure showing the Rev A
- A document with KIM-1 program called KIM-1 Application CT1
- KIM-1 Application Note 2 Interval Timer Operation
My Rev A CPU week 15 1976
