Congrats MS-DOS!

I may not remember correctly, but wasn't it that MS-DOS 4.0 was replaced by 4.01 two days later or so?

Also, typo below the MS-DOS 2.0 picture: It should be 5 1/4" (the floppy with the half one was 3 1/2").

Sweet DOS memories. I could probably still remember how to write CONFIG.SYS and AUTOEXEC.BAT files that wring out every possible byte of <640K memory so that Ultima VII would run. (This game had a home-grown memory manager which required an obscene ~620K of so-called "real" memory while also requiring certain drivers that ate into that real memory, making it difficult to run the game without manually customizing the DOS startup command files.)

Yea, the problem was the original 4.0 release was buggy.
