Nobody's really pointed out that MCA is a
*fast* bus. 66MHz PCI was
the first "generic" alternative to get even close to MCA's throughput,
let alone bandwidth.
The RS/6000 SP nodes used MCA till the way late '90s. They sure as
heck didn't do that because they had leftover parts.

VLB was 32 bit and ran 33 to 50Mhz, so it was faster then the 10Mhz 32 bit
MCA ( was there a 20Mhz version also?). Yes, I know VLB was limited to video
cards, IDE, SCSI, and I/O cards but those were the only ones that needed the
extra speed back then.
