I don't have any idea what this is but it appears to have Z-8000
CPU+MMU chips. Perhaps an Onyx or S8000 CPU card? I know some folks
here are in to that sort of thing.

Its not an Olivetti M20 but might be a M30 or M40. These were Mini class machines.
It would be towards the last of the Z8000 with a MMU.

just guessing with the number of I/O's it may be a controller board of
some sort for something which needed a lot of go power, or perhaps an
embedded OS.
The EPC part of the nomenclature kept hitting things made by Epson, so
maybe it is a scanner or printer controller?
The large number of connectors is what bothers me with respect to it
being a part of a general purpose mini. I've not seen many with so many
connectors of this type, and therefore cables coming to the main
processor. And in a chassis type mounted mini that would be a huge mess
of cables to run out of a card slot if it were a high performance
controller.
Can prove me wrong, but I'm guessing some sort of controller.
thanks
