    A good theory, however the PCjr's slowdown at very high interrupt rates (16 KHz) is much worse than on a Tandy 1000. So the Tandy 1000 is slower, but only by 1%, just enough to be audible. On an...

    Not to derail the conversation too much, but I'm publishing a video this weekend that proves the Tandy 1000 (the original) can be just a hair slower than the IBM PC, found when doing a...

    There are no ISA cards that can add a PS/2 keyboard.

    Wouldn't it be much faster and easier to just get a Tandy keyboard?

    Your stated goals conflict with the whole point of writing an opcode exerciser (to be as accurate as possible). Why not just fork DOSBOX and be done?

    Sandsifter requires a 386+ because it relies on invalid opcode exceptions (and while 286 has those, sandsifter is written in python so it still needs a 386-class system to run on). So you can't run...

    An x86 validation test would be extensive since the behavior of the x86 line changed with every CPU. It is more practical, IMO, to pick a single CPU and concentrate on just that until all of the...

    Sadly, Heritage Auctions is getting in on this with console games and it's leaking over into software collectibles.

    If the BIOS uses software loops for timing hardware events, a faster CPU will disrupt them. Is there a BIOS listing for the Amstrad PC1640?

    Tony and Friends uses 320x400 and 320x480, not 400x300.

    400x300 needed a very good multisync monitor so I'm pretty sure that specific mode was never used; I didn't even get it to work consistently...

    The leftmost one has a rough finish and the number "1" written on it in marker, so it was pretty easy to figure out, but I agree they look good.

    Ah, so you calibrate physics calcs for time unit N and then, to figure out how to keep the calcs accurate across time regardless of framerate, calc for N*M?

    Is this for Chuck Jones?
