Description
SBC-85 Backplane-4
The 8085 based SBC-85 was designed with an expansion bus having all 16 bits of the address, data bits, and all the status and control bits from the 8085. The Backplane-4 is a 100mm x 100mm four slot backplane that allows the SBC-85 to be expanded to other cards such as the cassette interface, paper tape interface, I/O, memory, and whatever else the user group can envision.
Complete documentation on the SBC-85 system can be found on the project website.
