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. http://ethw.org/w/index.php?title=First-Hand:The_First_CMOS_And_The_Only_Cryogenically_Cooled_Supercomputer&oldid=154872 paul
