I received photos from Joseph Avins of a KIM-4 motherboard connected to a KIM-1.
Added tot the KIM-1 hardware pages, read more here.

The R6501Q and R65F11 IC’s I acquired are Rockwell parts for single chip computer systems. Well, they contain a lot more than a 6502, like ROM, RAM, I/O.
Found in my archive: the German version of the Elektor Junior VIA 6522 book.
Added tot the Elektor books page.
The article about the Fast Cassette Interface is part of my CW Moser Assembler/editor package. Scanned by me in 2010 to the file kimfastcassette.pdf and on my website with the CW Moser package for years now .
Glen Deas knew it was designed by Lew Edwards and entered the source in modern assembler format.
Glen Deas supplied negatives of 80-153 and the Z80 cards, thanks!
I also added the information I have on Apple ][ cards by John Bell, like the 6522 VIA and A/D cards.
Development for my old 8 bit retro SBC’s has become much easier with fast PCs and good tools. All cross development.
What took hours on my KIM-1: load editor form tape -edit source – save on tape (multiple tape files if big) – assemble form tape to tape – load binary from tape – run
can now be done very fast.
Powerful text editors, cross assembler, KIM-1 Simulator, seconds per iteration.
The only slow part remains: me!
More on my favorite toolchain here.
In 1982 I wrote/composed a program to have disassembled code on paper, with page numbers. Read more about it here.
The core routine of the disassembler is the well-known Steve Wozniak/Allen Baum 1976 article A 6502 Disassembler from Apple
The program is a TTY program. I build it with the then current hardware and software of my KIM-1:
Corsham Technologies produces a Bus Extender fot the KIM-1. SImple but so handy.
It is placed beween the external device on Application or Extension Connector and has 44 pin header to attach wires to a breadboard for example.
Only negative I can say about it, tinned edge connectors and not gold plated.
Nice addition to my Reproduction KIM-1s!
Dave Wiliams made a revison of the MOS KIM-1 Reproduction, a white version.
The original green and the new white are for sale at ebay as of January 2023.
