RISC PC Econet Module
RISC PC Econet Module
Here it is at last. It's a little bit smaller than a Master series Econet Module, and square. By this point, most components are surface mount, but the 68B54, 26LS30, IC8, and the Econet ROM are all proper through-hole chips. I'm not sure what IC8 is, probably a custom programmed chip. The connector is the 48-way plug for the network socket on the RISC PC main board, and the Econet connector is the 15-way D-type introduced for the A4000.
