Question for all you who know old OS's

[Neodude1123201]

Sounds to me like a Generic DOS Shell that started automatically started from the AUTOEXEC,So it didnt look like it was from DOS.

It wasn't 3.1. An old Mac OS? I'll look into it... but could it have run on a Compaq?

The old DOS I'll also look into, for mac it would have to be pre "Mac OS"... I'm thinking what... system 4.*
