Ok. If I can find any of my 32MB ones, I will try it and let you (and
the list) know if it will recognize additional memory.

Wow! Good news!
I was so curious that I verified wich type of memory is used on USG
board : RAM chip was MT4C4001JDJ-6? (FPM memory type).
Here, I had an old 72 pin memory SIMM of 16Meg EDO RAM Nanya
NT511740B5J-60. Same speed but FPM vs EDO memory type.
After reading several documents, I took a chance and…lucky man, every
thing was OK, UTH option was automatically detected.
I tested option w-cdma without any problem (who need UTH to works
properly).
Maybe it's too soon to know if the long term stability will be OK, but
my 89441A was still OK after 4 hours of utilisation and a few power up.
This is great news! I think it's safe to conclude that it works; it would
likely have failed very early during the memory tests if there were a basic
incompatibility in the memory type.
I wonder if it's possible to add more memory. Somewhere I have some 32MB
72-pin SIMMs, I think they are EDO. Do you have any that you can try?
