I'm not sure what this is. The big ceramic cased device is an 8x300 series
part, maybe 8x305? I can double-check that if anyone's interested. The
rest of the board is generic TTL mostly.
It says on it "WD1001" - it's a Western Digital WD-1001 disk controller.
I've never had one that old, but it resembles other 8-bit disk controllers
of the era that I have seen. The mounting bracket makes me think of one
of the early clone machines - Eagle?
It appears to support up to 4 drives (from counting connectors).

This one I have no idea about, most of the 14/16-pin parts are generic
4000-series CMOS and the 8-pin parts appear to be linear chips, op amps and
such. The second pic is the panel on the left side of the first pic.
I don't know what that one is, either, but UDS made modems and autodialers
and such - perhaps some critical telecom-function daughtercard sits on those
female molex connectors?
