Apparently the article was folderized at some point, but the new CSS makes it so that paragraphs aren't spaced correctly in folders. Is there a good way to fix this without taking the folders back out? This is kind of a long article, so I don't want to go back to using !! markup if I don't have to.

I tried fixing it while keeping the markup, but the CSS is just not co-operating, so the folder markup is back out for now. We may want to consider splitting this article up.

What's that with the CP/M predecessor? Wasn't it RT-11, a one-task RT OS, while RSX-11 was much more complex and supported multitasking? BTW, when DEC switched from PDP-11 line to its 32-bit extention, the VAX, it was RSX-11 developer, Dave Cutler, who was given the task to write a reference OS for the new platform, the famous VAX/VMS. Which later, when Cutler left for Microsoft, resurfaced in a new form as Windows NT.
So it's basically TWO different non-intersecting lineages, as follows: RT-11 -> CP/M -> Q-DOS -> MS DOS -> Windows (classic), while the other line is RSX-11 -> VMS -> OS/2 NT -> Windows NT.

This reply is extremely belated, but yeah, I wrote a lot of the original article from memory and so there are a few things I got wrong.

Some footnotes that probably don't belong in the article, but I wanted to write them down anyway:
- There were a few ISA cards that could indeed do bus mastering, typically by fooling the ISA DMA controller into giving them control of the bus. The most famous of these was the Adaptec 1540/1542 SCSI HBA and its clones and follow-ons. It should be noted that this was a hack (though not nearly as awful a hack as VLB was; the 154x was rock-stable when tuned properly), and would crash systems with DMA problems or just plain bad build quality (much more common back in the 386 era than it is now); indeed, the 154x BIOS even came with a diagnostic test to see if the hack would crash your system!
- Before VGA came out, there were a few "Super EGA" and even "Super CGA" vards as well. The ATI EGA Wonder (which had one of the first TV-out implementations, as well as a scan converter so you could use EGA modes on a CGA monitor) was an example of the first, while the IBMP Cjr's "VGA" system and cards like the Persyst CGA and the 400-line CGA on the Compaq Portable and AT&T PC 6300 were examples of the latter.
More tidbits as I think of them...

What's really funny about all those Super CGA cards, is that the most popular of them, the IBM's P Cjr "VGA", managed to enter the public memory under a "Tandy" moniker.
VideoGame.Rivals Of Aether is listed as a Booter game. Quite sure that name is only for the new game, and don't believe that it can run on DOS and stuff, but it might possibly, so I dunno.
