I have two or three of the PowerMac 9150s. I would need to check my inventory book to be sure. Yes, I've started keeping a list. Too many times I go through a box and think, "Wow, I forgot I bought that!" So now I have an actual list. But I digress.

I guess they could be 9100s. Was there a 9100 or only 9150s? Anyway, they're the big bruiser 91xx machines with either 80 or 120 MHz PPC601 CPUs on the motherboard and four NuBus slots.

I found one at the local Goodwill computer store, just sitting there on the floor like it was nothing special for some price under $50. Needless to say that went home with me immediately. I think I actually paid to ship another one. I'm not sure if I have a third, or if I'm confused because I have one or two loose motherboards.

According to PeterH on the LEMLists, there were a huge number of these available at some surplus mecca shop out in California several years ago.
