The 700 is fairly speedy and comes in an adorable, smallish case. It's not very good for the highest-end 68k tasks like video editing, but still has nice expandability.

It is a nice midway between compact machines like the Q605 and larger multislot Macs like the 900 and 950.

That MacProteus card is basically a late 80s digital synthesizer on a NuBus card.
