    3.30 - dominant for many years, due to problems with 4.0x
    5.0 - also very popular for a long time, due to problems with 6.0
    6.20/6.22 - last versions of stand-alone MS-DOS (DOSes other than MS-DOS...

    It's perfectly possible to support both, and well - see eg. Linux until 2012.
    However, it requires more work from the coder, as 486 supports CMPXCHG - an atomic instruction used in multithreading to...

    Run DEBUG, and enter something like:

    f b800:0 l 1000 0
    (for color video)

    f b000:0 l 1000 0
    (for monochrome video)

    For measurement of cache size, try eg. CTCM - http://www.theflatnet.de/pub/dos/ct/
    In the 486 era, there was a lot of motherboards with fake cache chips, so that program was a must-have...

    Most likely it's because the card pays attention to the Monitor ID pins, especially pin 12 - not connected in the original IBM VGA color monitor, connected to GND in monochrome monitor.

    How many PCs for all the games?

    How many PC machines does one need to play all PC games?
    Well, *almost* all - I don't care about some crap games that only run on some very specific hardware.
    I don't care for the games to run to...

    Actually, that single-diskette version of QNX could be pretty useful - just not as a general-purpose desktop OS, and it was never supposed to be one.
    QNX is a real-time OS, well suited eg. for...

    Sure, it's not a problem to find a GUS Classic (or a clone) for a reasonable price.
    And there's many Sound Blaster cards that go for pennies.

    But there's a problem with putting two sound cards in...

    Definitely IDE - it's the last sound card by Gravis, even later than those Interwave-based ones, released when proprietary CD-ROM interfaces were already extinct.

    That card is precious, as it's the only card that's compatible with both SB and GUS - basically, it's "two cards in one".
    But still, that price is much exaggerated.

    You know, he also said that "640K ought to be enough for anyone" - that must be why he later criticized a chip that allowed for more :D

    There's plenty of software for benchmarking various display adapters: Checkit, Landmark, Topbench, and many others.
    Checkit can also be used to test video memory - and this may be your problem.

    You know, 286 PCs came out in 1984 (IBM 5170), and a year later 386 PCs weren't there.
    If you're talking about the Windows 3.1 era (1992), then 286 was already low-end, or even obsolete, so no...

    The Windows version (HWiNFO 32) has also been around for decades, version history mentions eg.:

    If there's a "286" somewhere on the case, but inside it's a 386, then yes, it's ugly, and I tend to avoid such things.
    The difference between 286 and 386 is huge, 286 is 16-bit, ie. absolutely...

    However, some websites are still accessible by vintage browsers - see eg. Wikipedia, still pretty readable under Lynx.

    Drivers specifically for CT2770 probably don't exist.
    Just try various Sound Blaster 16 driver packages, at least one of them is sure to work.

    Let me guess: MFM drives were connected to an XT-style controller with its own BIOS, and IDE drives weren't defined in CMOS Setup, instead controlled by 4DRIVES.SYS, right?

    Actually, support for 15 kHz video isn't a big surprise.
    Modern monitors share a lot of circuitry with TV sets, and TV sets are supposed to support PAL and/or NTSC - and both are 15 kHz.
