BetaDOS is a new MetaDOS implementation and was created February 1998 by
Ulf Ronald Andersson. It is compatible with all known multitask systems
based on MiNT or MagiC, and includes a filesystem driver which gives TOS
users access to a 'unified' drive similar to how U: is used by both MiNT
and MagiC. BetaDOS contains many improvements over MetaDOS but is 100%
compatible with Atari MetaDOS 2.70, and also with ExtenDOS, so BOS and
DOS files used with MetaDOS or ExtenDOS may also be used with BetaDOS.
