Welcome, this is trs80m1-mltl, a machine language "tape linker" for the TRS-80 Model I personal microcomputer. This utility takes a raw binary file, and packs it into a format which Level II machines can load into memory and execute using the command `SYSTEM'. The output file format is CAS, which can easily be used by most emulators, and with the use of a conversion utility, can be recorded onto a real tape as well, for use with real hardware. The purpose of this tool is to allow the development of TRS-80 Model I tape software in a modern environment. In particular, it's been tested using the ZASM assembler, which you can find here: http://k1.spdns.de/Develop/Projects/zasm/Distributions/ You can find example programs in the `examples' directory of the project.
