I had no idea people were making OMNIBUS boards in 1995. That's amazing.
There are still machines in commercial use, but most of them are so deep
inside something else that nobody knows how to upgrade them, let alone
_want_ to change out the old for the new.
I see they are a British company (http://www.tellima.co.uk) I guess that
means that their products will be a wee bit less common on this side of
the pond.

It has a couple of surface-mount KM68100 SRAMs,

It's a commercial 4-layer board. The legend says "Tellima Technology Ltd
(C) 1995", "PC03753"... 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
interface.
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
miniDINs.
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...
