ID this board?

Thanks Tony,

There are several large chips that say "Xilinx XC2018-70 PC84C A6396A9103E."

More revealing, maybe, is what I just spotted amidst stickers and components: "Central Processing Unit." Heh. So this appears to be a big honkin motherboard from some...analytical thing. Another largish chip says "Dallas DS1287 Real Time" followed by more numbers.

I am gonna hang this on my wall. Unless someone on the list is dying to have it.

I've sort-of come across a company called 'Link Systems'. In fact one of
my ASR33s (Data Dynamics case/electronics) is badged by them.

instruments, spectrometers, electron microscopes, that sort of thing.
The computers were sometimes based on PDP11 CPUs (or occasionally DG
Novas IIRC).

They may well have designed their own CPU boards later on, but I've never
seen anything like that.

My guess is that you've found a board, possibly an interface, possibly a
complete CPU, from one of these instruments. What (if any) large chips
are on it?
