Found a USIIi/440, went to put it in, my PROM didn't support it, had to have an update using a 300-333 MHz CPU. So it goes. Anyway, that's not a problem. I took a second look at the old card and got it working. For some computers that are almost on topic now, there's a bit of a hidden catch on the CPUs- they aren't firmly attached, and on some of them (I know that SGI PMT5 modules do not fall into this category, but HP PA-8000s and USIIis do) the connection is effected with a sheet of something with conductive rubber blips on it (sound familiar? Wonder how these will work in ~20 years). If you are not careful to go round-and-round the merry-go-round with the device to snug up the heatsink, the processor becomes canted and does not make good contact, and becomes generally unhappy and huffy and will not work (how's that for a run-on!) End of story- I now have an OT Sun Ultra 10 440MHz with Solaris 10 on it- Solaris is much happier on SPARCs than PCs. Western Digital IDE drives from the late '90s to early 2000s seem to be going bad at shocking rates now, also. Beware.
