Are any of those folks still hanging around where they can be contacted? Every now and then I come up with a question... Today's is why are there 32 contacts available on U42? U42 is the NVRAM chip. It's an 8K X 8 SRAM which only uses 28 pins. There are larger SRAMs available, and I suspect that they inserted an option to use a larger NVRAM chip, thus creating more space for Open Firmware patches, but who really knows. The other interesting thing is that there actually is a 32K X 8 SRAM chip available which only has 28 pins and is mostly pin compatible with the existing chip. There are a couple of extra address lines at pins that are NC on the old chip. That makes me wonder if they ran address lines to the NC pins so that a larger chip could be installed.
