Have you ever seen a IBM TCM?
Yes, but conductors on substrate are slower depending on substrate used.
They are dense but TCMs still have to talk to other TCMs.
That
depends on how tight everything is. Thermal Conduction Module, anyone?
At 1ns/ft even the TCMs were not tight/dense enough. Crunching
numbers was a part of the task. The other part was moving
and handeling data in mass storage and memory. Most of the DEC hardware
moved data pretty fast. What was the demise of PDP-10 was simple, megabytes.
And being six bit machine in an eight bit world... --
