Hi,

I started working on a Mastodon client for MS-DOS using my long-term pet project DOjS (Javascript rutime on MS-DOS).
Code (that is actually runnable) can be fount here: https://github.com/SuperIlu/DOStodon
You'll need at least a P133 with 16MiB RAM and a network card with a matching packet driver.

cheers
Ilu
