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.
START - Where the program is ORG'd to run from.
LENGTH - Size of executable data, this does not include the header(6 bytes), just the length of EXECUTABLE DATA.
ENTRY - Where the program will be entered (entry point).
EXECUTABLE DATA - 8085 machine code ORG'ed at START.
