Some great reverse engineering, and a couple of interesting homebrew CPU designs: a 14500-ish 1-bit CPU using an EPROM, and a 24-bit extension to the 6502.

Notable for "Great Microprocessors of the Past and Present", along with some very silly short stories.

Various unusual and clever electronics projects. I particularly like the PIC-based SC/MP emulator (for a Mk14 rebuild), and the FM stereo modulator built from scratch.

High-resolution photos of microprocessor dies. The PIC16F84 picture is particularly cool. There's a schematic of the 6502 here too.
