[sdiy] Ursa major UART: WD2123

[MTG]

That's a tough one. The "DEUCE", Dual Enhanced Universal Communication 
Element. Does it require a baud rate generator chip? I assume you've 
ruled out the obvious -- the chip(s) between it and the world?

Long shot, but here is one maybe:

It was used in a Ursa Major 8x32 that I'm working on, and it needs a new one to get the CPU running again (the UART blocks it). They used to use these chips in various vintage computers too (FDD3000, etc). Anyone have a working one?
