Elektor Junior computer large update

After finishing the large update a month ago of KIM-1/SYM-1/AIM 65 I turned my attention to the Elektuur/Elektor archive, mainly the 6502 period of 1978 to 1985 where the SBC Junior Computer and EC65/Octopus systems were introduced.

New and enhanced in higher quality information about these systems:
– published in multiple languages and more content of articles and books scanned, not only dutch bnut also English, German, French, some Spanish and Italian.
– better hardware descriptions and photos of PCBs etc
– more complete software library, sources of systems ROMS etc.
– gallery of Juniors, EC65 and other cards and cases

Start here for the Elektor/Elektuur/Junior/EC65/Octopus pages.

KIM-1 Clone

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.

Available assembled and tested or as a kit. I have bought the PCB and plan to build it!
