And here it is: SvarCOM 2021.0 (a.k.a. "preview release"). http://svardos.osdn.io/svarcom/ As I mentioned before, this is a work-in-progress project. It is functional, though, hence feel free to try it out. It is esp. useful on older machines without XMS, where the current SvarDOS shell (FreeCOM) consumes quite a lot of precious memory. SvarCOM takes only 2K of RAM and leaves all the rest to applications. If you wish to take SvarCOM on a test run, please make sure to read the TODO.TXT file to understand what isn't implemented yet. The most annoying thing is probably the lack of an INT 24h handler, this may lead to surprising results if one tries to access an empty floppy drive.
