MS-DOS 6.3 and 7.10.2400
One of the experiments i have been doing is playing around in 'recovering' the DOS 6.22 and 7.10 utilities for a "generic DOS" thing.
As part of the process, i manufactured a "genuine" MS-DOS 6.30 that reports that to every program, and a complete version of MS-DOS 7.10 (from Win95-WinME source tapes).
Help is still QBASIC etc, but the whole thing is rebuild using various known patches (*.TXT -> *.*, Phatcode A: bug). DOS help can be accessed inside the DOS editor.
Finally, i decoupled the version test for some rather interesting tests.
