Xpantastic!

*cough* Er, to be honest I hadn't bothered to compare the schematic to the 
physical board. But you're right; 8K static RAM chips in the diagram, and 2K 
static RAM chips on the board...

And since the serial number on mine is 700290, it looks like I have a Japanese 
Xpander, although the plate on the back doesn't say where it was made. And the 
PSU board clearly has "Made in U.S.A." on it. Interesting.

And I guess our chances of finding schematics of the "last edition" processor 
(and other?) boards are approximately zero...

Cheers,

John :^P
