MAC-02 schematic

[urq]

... I'd imagine this is the same file you can find on Robert Houk's urq site
...

I believe that Robert was not the source of the schematic ... he was just
posting it as a service.  This schematic was reverse engineered by someone
named Rich Thomas if memory serves ... and it is by no means complete ... or
guaranteed to be correct.

What is it that you are looking for a MAC-07 schematic for?  Are you looking
to repair one, or perhaps to investigate chipping?  The MAC-07 uses an
integrated microcontroller ... where the program memory is integrated with
the computer.  This sort of situation would be considerably more difficult
to "QLCC" IMO.

If you were looking to repair a broken one, it might be easier to hunt down
a replacement ... I think I got the one I have on eBay for $10.  I'm
actually building up a small collection of bad "MACs" ... I'll probably be
putting together something that will allow me to work on them on the bench.
I'm wondering if there are very many others out there with ECUs that are
nonfunctional sitting on the shelf ...
