I was thinking of going up compatability in versions, such as going from 1.x

And of course, it'd be IBM PC compatable stuff, not the odd machine MS-DOS
running thingies
I'm rather bored, so I thought I might try and hack together a small project
OS compatable with at least DOS 1.x or similar, is there any decent resource
for information on dos compatability and how to achieve it, or is it left as
a reverse engineering exercise for 'the reader' ? :)
How compatable? If you go by the published API for MS-DOS 1.x, then it
should be pretty easy, but if by "compatable" you mean "run arbitrary
MS-DOS
programs, especially those from Microsoft" you may have your work cut out
for you. You may want to check out http://www.freedos.org/.
