NCR also made Microchannel machines, including some quite large ones
(Worldmark 5100, which at some point I had a couple of).
I worked with some large NCR MCA machines in the late 1990s when I was
at Lucent. Imagine a machine larger than a VAX 11/750 with four
Pentium-90 processors, multiple MCA buses and many SCSI cards on those
MCA buses and many, many disks... the scary part was it was still so
PC-compatible that it could still boot DOS and run Doom.
