Collectors Corner: Schematic Diagrams & Diagnostic Routi

[klute]

Hi all

I'm trying to troubleshoot two Fidelity Designer Mach III Masters and the lack of factory schematic diagrams and diagnostic routines is making life difficult. I've been doing some high level diode & voltage regulator tests etc. and things seem to be working to reasonable tolerances, but I'll need the factory technical documentation to dig deeper. Without factory stuff it's really like looking for a needle in a haystack.

Does anyone have access to factory repair documentation for this model who could perhaps e-mail me a soft copy? Specifically I'm after these at the moment:

Fidelity Designer Mach III Master - Board Review 510.1134A02 (1989)
Fidelity Designer Mach III Master - Board Review 510.1146A01 (1990)

I note that Issue 129 of Selective Search Magazine has an article on Chess Computer Repairs - does this happen to mention sources for schematics / diagnostics documentation?

Thanks

Cameron
