Yeah, that's what the +/- 25v circuit breakers were for. If the CPU card is
dead (or the monitor cable install backwards), the inputs float and as soon
as they overcurrent the circuit breakers blow. This genuis of a circuit has
probably killed many a monitor...
..yup, sort of what I figured
I just spent an hour or two doing analog switch research and it looks like
the 4066 was designed for fairly low voltage unipolar operation. It looks
like the DG411, MAX312 quad spst switch is fairly common, and it looks like
if you supply +5 to pin 12 on an AVG board, a MAX312 should work as a
replacement for an LF13201.
I would (obviously) be interested in seeing the color converter board
schematic when you have a chance to scan it in..
