I was trying to buy another chip for my 90 and they are NLA & out of stock at GM.
I did some looking around and at least I found where all the 90 PROMs are at. You proly can guess where they are, maybe the rest of the PROMs for the 91-95's ended up at the same place?

Tom, I have a 90 Zr-1 prom. I will sell for what I paid. Thought a 90 prom would work in a 91 and was wrong. If anyone has a 91 and needs a 90, we could work a trade.
