Interesting. A framebuffer. But why four DACs?  The framebuffer itself is
the 72 16kbit DRAM chips. Slightly more than one megabit. Not much being a
color framebuffer. I wonder what the colordepth and resolution was on this
one. 256 x 192 and 8 bits per colour perhaps?

Anything else known about it except for what Lyle dug out?

There is two different kinds of test. One is to give them a fixed dose and then 
check to see if they are still operational. The other is to zap them until they 
fail, and then diagnose the failure/s.

It's a frame buffer, you can see the 10422 lookup tables behind the TRW video 
DACs

Here's a little more information on where this board set was used (see
page 6):

That one is easy to name: That's an Able Quadrasync/E, I have that board, 
too.

Four Unibus boards from radiation dose measurement system.

[Mattis Lind via cctalk]

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?
