Re: DR-DOS and secret APIs
"So all those who claim to have not been able to run Win 3.x with DR DOS were running the beta."
And DR-DOS had worked around it by then. But that they attempted it at all was indicative of Microsoft's attitude. Then there was the way they shafted Lotus, Wordperfect and Ashton Tate so that MS Office became the pre-eminent office suite. And then there was that contretemps with Netscape. I can't vouch for what they did with Win16, since I went straight from DOS to Win32, but Ralph Brown's interrupt list was a godsend in the DOS days.
