I did one of these many years ago. The non midi verion is the same board
with parts not fitted, although it's possible there were different board
revisions.

The midi in and out drivers are near the holes in the back, but there
were extra components around the individual drum voices elsewhere on
the board.
I have all the documentation and a broken scanner - if you're in the UK
(or maybe Europe) I might consider posting the stuff to you, otherwise
it'll have to wait 'till I get a new scanner (soon hopefully).
