Put a load that pulls about 2A at 5V (a 10W 3 ohm
do) and see what your readings are.
I built a test load by putting three one Ohm 10W resistors (available
at the local Radio Shack) in series. With the test load, the +9 rail
goes down to a little more than 8 and the +5 rail goes to about 4.8,
smooth as glass on my scope. With that test, I decided to go ahead
and reinstall the ICs. I've applied power and the +5 rail is between
5.1 and 5.2. The system seems to function as far as I can test it with
my limited operations knowledge. I can deposit values in memory and
they remain as long as power is applied. Now I need to learn a little
6800 machine code and try a short program.
Thanks for all of the help.
