Yeah.
For what we needed, five 32 bit address spaces was enough DRAM. The individual CPU parts were way more than 20% as fast, and the 100Mbit switch was good enough.
(The data basically fit in ram, so network transport time to load a machine was bounded by 4GiB / 8MiB / sec = 500 seconds. Also, the hard disks weren’t much faster than network back then.)
