After toying around with the simple EGA video out stuff, I started thinking about bench testing/troubleshooting for the compact macs. Would anyone be interested if i were to design, test, and publish gerber files for a troubleshooting board for the 128/512/plus? I figure the device could be used between the logic board and analog board, or independent. nothing fancy or anything... but it would sure make things easier
Possible functions:
Video out
power select from either analog board or ATX power supply
test pattern generator for checking and adjusting CRT
select between analog board battery or test board battery
keyboard adapter to use either ADB or PS2 keyboard (would require connection to keyboard port on front)
speaker
indicator LED's for +5, +12, -12 and +4.5 from analog board (to get a general idea if they are working) with a pad next to each for easy checking with volt meter
Can anyone think of other features that would come in handy?
