Ithaca Audio and friends

Ithica Audio, some pretty neat systems. I used to call on them as an apps engineer back in 1980. I wouldn't mind finding one or at least the floppy controller as I had some influence in the design. <> I also found a National Semiconductor Board Level Computer (BLC). It's <> 8080A single-board computer from 1977. There's also an unpopulated RO <> board in the small card cage. I know zilch about this one. There are <> plenty of unconnected edge-connectors on the CPU board and an on-board <> 8251, so I assume I can make this one fly if I simply figure out the I/ <> connections and power requirements. IF it has two edge connectors it's multibus and it was made a few years later as National was not in the multibus market till 79-81ish. Allison
