Build kit

The GAL22V10 PLD

A kit in the Hardware Basics series. A chip whose inner wiring is set by a file. You start with a new transistor — one with memory — build an 8 × 8 mini-PLD from 64 of them and program it by hand: an adder, a comparator, two NOTs — on the very same circuit. Then the real GAL22V10: a 44 × 132 matrix, a macrocell from familiar chips and the whole ready chip. Equations turn into a .jed file right on the lesson page, and one board becomes a display of digits, letters or an electronic die. A standalone kit. 6,932 transistors.

The introduction and lessons 0–1 are free; the rest opens after purchase.
