[rescue] ultra 1 with weird errors

[laz at moaa.net]

I recall seeing that error when a friend tried to upgrade froma sparc 5 to an Ultra 1
by just moving the hard drive.  You might pop a CD Drive on and try booting off of it
to test.

Having said that, recently got an old U1 that the Prom is blown on, anybody have one
availabe, or whats the best place to get a replacement these days?
