KIM-1 Clone

Posted on 04/01/2019 by hanso

A KIM-1 clone build by Bob Applegate of Corsham technologies.

Somewhat inspired by the microKIM by Vince Briel, who was inpired by Ruud Baltissen! The idea is replace the 6530’s with 6532 and by carefull memory decoding have the I/O, timer and RAM of the 6532s appear at the same locations as the 6530-002 and -003. ROM is added with an EPROM.

Not an exact copy, the ROM has been changed/enhanced with a KIM Monitor by Bob, though the original KIM-1 ROM should work also.

6501 photo and datasheet

Posted on 27/09/2018 by hanso

The MCS6501, a first and very rare member of the MOS Technology 65xx CPU family.
Introduced in 1975 with the MCS6502 to MCS6505, pin compatible with the Motorola 6800 and, after legal issues, not produced afterwards.
The (preliminary) datasheet of August 1975 is the only document where the 6501 is documented
