SRA / Ericsson C600
Replace the expensive and hard to
find 27S13 BPROM with a reprogrammable 2716 EPROM.
Remove the bprom from the holder and
attach a piece of Veroboard with a prom socket installed. Make the wire
connections according to the diagram.
The plug adapter for reading the code
plug content into the prom burner is made from a card connector and an
eprom socket. The wire connections are similar to the eprom adapter.
