grainy video

Had an interesting occurrence. On powering up a IIgs the video was grainy. Turns out I was getting only 2 volts on one of the 12v pins. Swapped in a spare and video was normal. All the caps and everything look ok. I guess it’s time to upgrade the power supply.

Yup, definitely replace that PSU! There's a kit for sale to upgrade it to a modern one. Look around and you'll find it.

I'm prepared for this, I'd previously picked op some medical grade power supplies for this eventuality. Actually I picked up ones that I could squeeze into a Vulcan. With the Apple power supply I don't have to do any squeezing.
