PSX (ORIGINAL) Power?

My first goal: To make my old Gray PSX to work off of a battery.

Does anyone, at all, have a pin configuration and voltages for the original gray PSX's power pins?

I would plug it in with the top off, but there's something about frying myself that I don't look forward to.'

Danke.

You could at least try searching:

Aight, Thanks. I'm a big dolt. Duhhhh. *Drooling*

EDIT:

Okay, I have a second question. Does anyone know the voltage tolerance for the original gray PSX's? Seeing as the input voltage would be 3.5v and 8v, would I be able to get away with using a 3.3v regulator and connecting my 7.5v NiCd battery straight to the 8v lead?

You could try

BUT!

WHen batteries are fully charged they might exceed 1.5 v per cell..

so your 7.5 v might suddenly be 9.2 v. This happened to me..

It made me change my powersupply design to incorporate a zener to clamp the voltage to 7.4ish volts.

Note though that if you do this, you sacrifice efficient use of the battery.
It WILL dissipate some stored energy as warmth..

Try it with a switching regulator to make it 7.5 volts, and from there on to a 3.3(to 3.5) volt regulator. I use an LM317 with a big power transistor across it. (the lm317 is just for stabilising the voltage. Current is supplied by the tranny)
