I know I can turn on an ATX power supply by connecting
the green wire to the black wire next to it. This
doesn't work for the older AT power supplies. What
is the trick for them?

TIA

I think they just need a minimum load ... a hard drive
ought to do the job.

Thanks for responding. I just didn't pay close enough
attention: the AT and ATX supplies use the same pins
to turn on, the wire colors are not the same across
brands. For the record, if you hold P1 with the catch
on the top and the pins facing you, you connect pins
3,4 on the top row counting from the left.

These power supplies are useful for other sources on
the bench.
