Many thanks, and though I don't understand all of what was said (which is a common occurrence for me), I get the general idea well enough. So, before I chuck the RAM in the eBay bin: Are there Quadra-era Macs or early PPCs that 72-pin 64MB EDO chips would work in?

The Quadra 605 (LC 475) motherboard will take 64 and 128 meg SIMMs, as will the PowerMac 6100. From what I've heard, yet without enough confirmation, so will the Quadra 840av.

I'd rather not go tearing down a Quadra 800, for instance, if the wee beasties just aren't going to be recognized as 64MB chips in it. On the other hand, if they would work in a Q800, A/UX 3.1 running on a machine with 256MB RAM would make the tear-down well worth the trouble.

The only way to get A/UX with 256 megs that I know about is the Quadra 950...
