The structure of a Model T CO file is very simple:

  • START
  • LENGTH
  • ENTRY
  • EXECUTABLE DATA

Where START, LENGTH and ENTRY are 16-bit words in little-endian (Intel) byte order.

The LENGTH does not include the START LENGTH ENTRY header, just the length of EXECUTABLE DATA.

The contents of EXECUTABLE DATA needs to be 8085 machine code ORG'ed at START.
