I agree : you need some kind of P-device to create a CMOS circuit.
The difference between enhancement or depletion devices is of little
use in this, I think. One could think of tricky alternatives for CMOS
using only N transistors, with a steered N as pull-up, but that would
really complicate the design. So, the question remains what Cray uses !
If Cray Computer already has some unix sites installed, they might
tell us... :-)
