Hi Steve,
Well I can guess that you picked up another power supply!
You can usually assume that +5 volts is used if it is TTL (+12 volts on CMOS)
amd +12 and -12 for the RS232. The negative supplies are the lightest amperage
while the +5 is the heaviest. If it is an eariler microprocessor then -5 could
also be used.
You can get into some weird stuff. One terminal I remember used +70 volts for
the monitor. It sounds like ratings were stamped on the PS.
I will still look up the area's hamfest and post them tomorrow.
73 Eric...
