Hello all,
Yesterday, I brought my PDP8/a (with core memory) back to life, I got from our institute.
It works, although the fans and the console panel (the plastic part, not the electronics)
are missing.
Now, what are the voltages of the fans ? I suppose that they're working with
alternating current.
They've to be replaced (somebody apparently "needed" them...).
On the power supply, there is a dead thyristor/SCR in the 5 volt regulator circuit.
As the machine works fine without it, I suppose that its function is to prevent high
voltages, am I right ?
So far, thanks alot for any help in advance !
Pierre
