KIM-4 by MOS/Commodore

The DigiBarn thanks Eric Johansson for this contribution of a rare KIM-4 motherboard (extender) for the KIM-1 (for adding S-100 boards to a Kim-1). From George Page's notes on Commodore:


The first computer marketed by CBM. It had been developed by MOS Technologies prior to MOS' acquisition by CBM (1977). It was basically a bare-bones 6502 "trainer". 1K RAM, 2K ROM. With the optional KIM3B memory board & KIM4 motherboard were expandable up to 65K.
