It's a funny little machine. It's as if it was not meant to have an 
internal disk drive. Perhaps if you sacrificed the floppy drive you 
could squeeze one in there. A small knob on the back to choose screen 
resolution. Only one ISA occupied by a monstrous graphics board parallel 
with the motherboard.

I'm most curious of a little "daughterboard" which seems to be some kind 
of upgrade, perhaps cache? Here is an auction of a motherboard/graphics 
card combo:

Notice the blank PCB near the ISA slot, on my machine it's occupied by a 
populated board. What could it be?

I'm a little disappointed there is no room to fit a sound card. Would 
have made a great gaming machine.
