While we're on this topic, I wanted to mention that I am looking for a 67MB
version power supply. I have taken pictures of the two kinds of UNIX PC
power supplies should anyone be interested:

Earlier "7300" UNIX PC Power Supply.

There seems to be some confusion about what you call the 67MB UNIX PC. Is
it a 3B1 or a 7300?
I also need an earlier 7300 motherboard.
For either, please contact me directly.
Thanks.
Bill
