I'm still looking for one of the above. This was a daughterboard designed to sandwich between a Z80 and its socket. It carried the Corvus proprietary chipset and permitted any CP/M machine to become a client on their Omninet network. If anyone even knows who has one, I'd appreciate a lead. In a pinch, given good photos I can likely reverse engineer the PCB and build my own (have a slew of Apple 2 transporters to harvest the chips from). The device is mentioned in one of the Appendices to DRI's CP/NET technical docs, FWIW. Steve --
