Bill Gate was a no-show, because he was in NYC on national TV being interviewed about the PC anniversary I was dropped from the beta program when I declared that SCANDISK was a disaster, and would eventually require a recall of DOS 6.00, When they did the "FREE" "Stepup" from 6.00 to 6.20, they let it continue to be blamed on the disk compression, although SCANDISK was actually the cause of the specific problems that warranted the replacemnt. Details available on request. STAC Electonics ("Stacker"?) had previously been in negotiations and technology information sharing, to be included in 6.00. Some usual unreliable sources claimed that STAC had demanded a royalty for inclusion of HALF the DOS price! When the deal collapsed, STAC sued Microsoft for infringement, because Microsoft hade kept some of the STAC code; Microsoft counter-sued, because STAC had started using some of the code from Microsoft. BOTH suits won! But Stac was awarded more than twice the damages that Microsoft was; Bill Gates said, "I'm having a bad day." (What I might say if I couldn't find the $20 bill) Microsoft released DOS 6.21 (same, but with no compression software provided) Then Microsoft wrote or commissioned a non-infringing compression, and released 6.22 (same, with non-infringing compression) I'm not sure whether Windows 95 could run on 80286; but most later versions required 80386[SX] or above. -- Grumpy Ol' Fred cisin(a)xenosoft.com
