Description
68retro MP-02 MC6802 Processor Board
The documentation, schematics,BOM is on Github;
https://github.com/crsjones/68Retro/tree/main/MP-02_MC6802Processor
*Not compatible with SWTPC original hardware*
The SS-50 and SS-30 busses have been changed to reduce the size and make them more suitable for prototyping with breadboard and Dupont cables.
Connector pitch changed to 0.1" from 0.156".
Change power supply requirement to 5V only.
Remove the Baud Rate Generator from the Bus.
Changed non-inverting Data Bus Buffers.
Information about this version of the SS-50/ss-30 busses is here;
https://github.com/crsjones/68Retro/tree/main/SWTPC/Bus
The connector is the Molex 22-15-2106, I purchase them from Mouser (538-22-15-2106). (Digi-key have them too)
0.1" pin header and female receptacles are a cheaper option but not recommended for more than a few insertion cycles.

Hi Matthew, No it won't, I changed the connector spacing to 0.1" from the normal 0.156" spacing. I also changed a few other things... I will add them to the descript_ion. Regards Craig
