Zenith Data Systems Z-150 ROM BIOS

BIOS-Z150-1988.json is a JSON-encoded dump of ROM images (444-229-18.BIN and 444-260-18.BIN) obtained from the Vintage Computer Federation forum.

The dump was produced by concatenating the two 16Kb ROM images to produce a single 32Kb ROM image and then running FileDump:

cat archive/444-260-18.BIN archive/444-229-18.BIN >archive/BIOS-Z150-1988.rom
filedump --file=archive/BIOS-Z150-1988.rom --output=BIOS-Z150-1988.json --comments --format=bytes
