These are the time test results for a PPC upgraded with a PowerLogix
board, G# processor 308 MHz, 1 Mbyte backside cache 1:1, 44MHz system bus,
MacOS 8.1 with many extensions. I could probably tweak the speed somewhat
by using only one display card and a better display card and SCSI 3 card
and drives. I am using inexpensive SCSI 1 drives.
