Texas Instruments TI-42 ROM |
/devices/ti42/rom/ |
Our TI-42 ROM comes from Sean Riddle, who decapped a TMC1502, photographed the ROM, and produced the following resources:
From the Original ROM (Big-endian), I created an Original ROM (Little-endian) binary:
node ../../ti57/rom/be2le.js tmc1502be.bin tmc1502le.bin
along with the corresponding JSON Data that the PCjs TI-55 Emulator uses:
node ../../ti57/rom/bin2json.js tmc1502le.bin > tmc1502le.json
See the TI-57 ROM for more details on the ROM format, including how the "raw" photographic ROM data is used to produce a working ROM binary.
