This is the list of "system ROMs", the builtin software on a chip that came with the Model T. The checksums use 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.

Tandy 200

The Tandy 200 system ROM spans 3 chips, 32k at M15, 8k at M13, and 32k at M14 (Multiplan).

M14 is not the Option ROM, but is bank selected in the same way.

Emulators such as Virtual-T sometimes use a single file which contains a concatenation of M15, M13, and M14, in that order.
