CMU has some microchannal PS/2's (model 60's, the 80286 variant) with an RT coprocessor board installed in them. They're installed in a public Andrew cluster. I don't know why they just didn't use the 80386 variant, since it might have resulted in even better performance (Andrew/Mach could use the '386 for disk and graphics, and crunch on the RT thing.) -- - Ralph W.

I should have mentioned it in my original posting. It uses a reworked version of the APC (Advanced Processor Card) that is used in the RT models 115 and 125. It is somewhat slower than those models, but I can't find the clock rate in the literature on the 6152. Anyway, that is not the RT follow on machine currently being developed here. -- Charlie Sauer IBM AES/ESD, D75/802 uucp: cs.utexas.edu!ibmaus!sauer 11400 Burnet Road 822: @CS.UTEXAS.EDU:sauer@ibmaus.uucp Austin, Texas 78758 aesnet: sauer@auschs (512) 823-3692 vnet: SAUER at AUSVM6
