I am pleased to report that I have managed to obtain a set of schematics for the MPT series Desktops. VIP Lothar located a section on the MPT in his fiche collection and I was able to have these converted to PDF.
This will make any repair on the MPT much easier and in addition it also documents the cabling required to interface the Winchester to the MPT/100 via the microNOVA I/O (apart from the terminator).
