Columbia Data Products MPC 1600 ROM BIOS

BIOS-434.json is a JSON-encoded dump of the ROM images (MPC4.34_U45.BIN, MPC4.34_U46.BIN, and MPC4.34_U47.BIN) obtained from www.minuszerodegrees.net.

The dump was produced by concatenating the three 4Kb ROM images to produce a single 12Kb ROM image and then running FileDump:

cat archive/MPC4.34_U47.BIN archive/MPC4.34_U46.BIN archive/MPC4.34_U45.BIN > archive/MPC4.34.rom
filedump --file=archive/MPC4.34.rom --output=BIOS-434.json --comments --format=bytes
