Lambda? (Later renamed VLSI Design if I remember right.) I still have the first issue, with an article by Ron Rivest describing the full-custom RSA chip (512 bit ALU) he designed.
As for CMOS for high speed computing, I recently read an interesting article about CDC spinoff ETA betting the company on that. It worked in the sense that the technology was a success, but the company closed anyway due to the fact that it was controlled by CDC.
