Incomplete Rebel backplane unit

Post by Pr0f »

This is half of the RB500e backplane kit - not sure what happened to the other half - I think it was consumed into another project and is long gone.

This piece is the 4 slot backplane - and might suit some one experimenting...

Bargain at £10 plus postage...

Did you happen to capture a schematic of it before you sold it?

This is only half of the original system - there was another board with a bunch of transceiver ttl devices on it that drove the 20cm ribbon cable - the grey strip on the left hand end is the IDC ribbon cable header (cable removed). The resistor networks just terminate the ribbon cable, and are on most of the signal lines.
