And since some have mentioned it, there was a 3rd party upgrade to the
11/70 which replaced the whole memory system with a few cards in the CPU
box, which turned all memory into cache.
This was by a company called SETASI, and the product was the hypercache.
They actually had two products. HC-70 was the hypercache, and then you
had something called the PEP-70 as well. It appears they could be used
together, but I don't know if one was required for the other, or if they
were related in any way, and if so how.
(SETASI also did other stuff, such as a SCSI adapted for massbus, which
was pretty nice, and usable both on 16-bit and 36-bit machines.)
