What I do is just tie one leg of R7 (someone might want to double-check
that number) to +5. On the CPU board it's an easy modification since R7 is
a big 1/4W resistor and one end of it is close to one of the +5V pins on a
neighboring TTL/LS chip. About 1/2" of wire and 2 seconds with a soldering
iron "fixes" the reset circuit. I run mine off an old PC-XT supply without
any problems.
