System Backplanes

"Acorn have two back­planes to interconnect their range of Eurocards with DIN 41612 Connectors. An 8 location backplane is in System 2 and 3 and a 14 location backplane for System 4.

The backplanes are single sided PCB's with provision for 64 way sockets. Side A (the standard Acorn bus) is connected by copper tracks along the length of the PCB and side B is connected by wire wrapping to configure a system for interrupts, cassette interfaces etc.

Both the backplanes have locations for two buffers on the processor address lines and power-supply connectors if required. The backplanes are suitable for 6502 or 6809 based systems."
