Folks, unlike the young MAJ Tom, fine pitch QFPs aren't as easy to focus
on and distinguish which pin I'm probing.
The XGA controller [G200 from Inmos] connects to D0-D31 and A0-A31 on
the MC bus through an octal 3 state transceiver [F245]. The F245 is a
SIMMple SOIC-20, and you can findt a SOIC-20 test clip all the live-long
day.
Still should be [SL]easy enough to use a SOIC 20-pin and probe to the MC
bus then swap sides, then probe to the G200. Still would like a QFP test
clip, but for something ~ $200 US, I can get by...
