Model T System ROMs

This is the list of "system ROMs", the builtin software on a chip that came with the Model T. The checksums used CRC32/PKZIP and CRC16/XMODEM. When a Y2K-patched versions is available, CRC checksum refers to the original ROM. Also see: the list of ModelT Option ROMs and the FlexROM 100.
