That
concerns me, as I'd rather not burn up a PDP-8/L (or the house).
What can I do to ensure the -8/L wont catch fire (or do anything else
equally bad) when I turn it on? I don't have a very good knowledge of
The standard drill - check the PSU on dummy load - certainly applies
here. Alas I don't know the PDP8/L (I have an 8/e and an 8/a), but I
guess if you either pull all the boards or unplug the backplane power
cables from the PSU, you can power up the PSU on its own and check the
output voltages with a meter.
There's info on pdp-8 power supplies, including schematics, at
http://highgate.comm.sfu.ca. Some of the technical documentation may help
in checking out the supply.
The H747 supply was used on the 8/e, the H740 on the 8/f, I'm not sure
about the 8/l however. It may be one of these supplies.
