The TRS 80 microcomputer was born in the USA in 1977.
It has many features in common with the British NASCOM computers and the Swedish ABC 80, expecially related to the way the Video and the Tape transfers are managed.
Many companies all around the world produced clones of such system; most of them will work with the current z88dk port.
The output code can be optionally relocated, but its default position is at $5200, which fits in most of the hardware and software configurations.
zcc +trs80 -lndos -lm -create-app program.c
This command will build a .CMD system file, ready for almost all the existing emulators.
If necessary it can in turn be converted in a “.CAS” file (see “support tools”).
This is a GNU licensed program able to get a TRS-80 compatible cassette file.
