OK, I have got the one for the 4MB board, although it's not the best quality 
(it's a photocopy of the original ACW service manual). I don't have the one 
for the 1MB 'cheese wedge' board though, although I know someone in London 
who's drawn it out and they're sending it up this way at some point.

The spare socket on the board is actually shown as an MMU in the schematics! 
Although it could potentially be used for other stuff - it has the top 8 
address lines, full 16 bit data lines, and various CPU control lines to it.

cheers
