This schematic on lycos:
http://members.lycos.nl/ijmtu/hpbimg/MAX%20machine%20schematic.jpg
was reversed egineerd from a MAX machine I had sitting in front of me.
Why not use that one instead of a schematic full of errors, made from some
unreadable copy?
Also the schematic on zimmers.net is not what is inside any max machine I
ever seen, maybe it's the schematic for the very first version of the MAX
machine ??
