It's a commercial 4-layer board. The legend says "Tellima Technology Ltd
(C) 1995", "PC03753". It has a couple of surface-mount KM68100 SRAMs, but
the most prominent features are the two Actel 1020 FPGAs. It also has 6 x
8837 and 3 x 8838 interface ICs, a pair of 74HCT244's, 2 x 74HCT160 and a
74HCT161, a MAX695, a 16MHz oscillator, a 3V 1/2AA lithium cell, a littl
daughterboard with some inteface chips, and the 26-way header for the PC

The PC interface is a small 4-layer ISA card "PC03285-C", with a couple of
Actel 1010's, a few small SMDs, 2 x 74HCT160 and a 74HCT161, and a 26-pin
header on the backplate. Interestingly, it also has space for a 132-pin
SMD device, several smaller SMDs, eight ZIP devices, and a couple of 8-pin

I don't have a scanner, at least not one that works. Nor a digital camera,
except my Indycams, which aren't exactly high resolution. I'll see what I
can do...
