the big picture


The Big Picture is a computer, an instrument, sassy companion, abacus and a cumbersome gadget for lighting LED’s. Composed of at least 50% wire by volume, the machine is a tool to give students an insight into the building blocks of a computer. On its deck are an 8-bit micro controller, 256K Static RAM, programming keypad, display, I/O decoder, A/D and D/A converters – all bound together by gluePAL (programmable array logic). Programmable in assembly (and initially by hand), building this machine was one of my fondest memories, de-bugging included.
