Hello!

I have four unibus boards that came in a 11/34 which was used for radiation
dose measurement at a hospital.

Three of them are made by Computer Design & Application inc and is a three
board set interconnected with over the top flat cables. It has some kind of
AMD 29xx based bitslice processor with 2903,2910 and 2914 chips. One board
has some kind of dedicated memory one board has 4 TRW chips which I think
are AD converters.

Then there is some kind of serial com board with four UARTs on it.

Is there any interest in these boards? Trade for something interesting DEC
stuff maybe? Or something else?
