Hey, look what I found ...

Quote:

MT.COM is about 2 K in size and can run up to 8 DOS programs simultaneously. They are launched in a command line like this:

C:>MT prog1.exe [params for prog1] + prog2.com [params for prog2] ...

However, MT is not a DOS-based Windows. It is primarily designed to run programs with none or line-based screen output, typically measurement and control applications. Also, each program has to ensure that it does not request the whole memory, or at least free enough memory after start to let enough space for the other tasks. MT does no preemptive multitasking but relies on the fact that every program should check the keyboard status periodically (typically using BIOS function INT 16H with AH=1 to check if a key was pressed). The task switching is done during this call.

The package includes some simple examples (including one for .ASM).

And here's a simple (but functionally useless) example via screenshot. Smile

If done correctly, you could easily write / tweak utils that would operate with this:


  • format floppy
  • copy or move files (small like this but better and FOSS)
  • search for files (within archives or otherwise)
  • assemble or compile your sources
  • anything else


Am I the only one intrigued?? Shocked
