I think it’s a Pluto 1A. The Pluto 2 was 12″x8″ and I’m not aware of any other 8″x8″ Pluto cards for the 80-bus. It may even be a later revision of the Pluto 1.
This was probably the ultimate in 80-bus graphics cards at the time. It’s a late issue IO research Pluto card with integrated palette. This system was very powerful (at the time) and was rather too expensive for most of us!
