    With MTCP there is no stack, there is only Zuul. Or, more precisely, there’s just a packet driver resident and each program runs its own stack that loads the IP information from the mtcp config file,...

    I assume that he wired the socket up to the "gated" MEMW coming out of the 8019A ASIC, not straight to the card edge connector.

    My two RTL cards have footprints on their boards for a 32 pin DIP,...

    That's awesome! It occurred to me after I posted that comment about it being a pain to have to initialize the card registers before using it that the config.sys exe wrapper I used for my stuff would...

    Honestly, despite having thrown out the line and my devil's advocacy for it I don't literally believe that IBM had a giant warehouse of cases sitting there they needed to use up. (Although there may...

    It's "historical" because it's old, I guess.

    It's kind of sad, really. This is the sort of thing that 25-30 years ago I would have been *thrilled* to pay $10 for at a garage sale and have fun...

    You could contact them and see if they'd give you a volume discount, they do that on a lot of parts. I buy generic TTL from them whenever I can because their prices are usually comparable if not...

    Not that anyone will ever power that thing on again, but it sure is kind of suspicious just how many empty sockets there are on the circuit board. Almost like the guy who built it might have borrowed...

    You can certainly do cheaper from eBay or AliExpress, but I trust Anchor to know what they’re selling.

    In the video it kind of looked like a lot of the dots were offset a consistent distance from the...

    Anchor Electronics lists a lot of different sizes in their price list (page 10), and I've always been happy to buy from them.

    Man, I hope for my family's sake that the trash I leave on my workbench when I'm dead will sell for that much.

    I think the big issue with the eZ80 is less that it's not strictly binary incompatible, it's that its internal I/O stomps on top of the addresses used by the TRS-80 and isn't relocate-able. The Z180...

    ... per the above, it just occurred to me how you could decode 640k with mixed 256k and 64k DRAMs using the same one ‘139.


    On the first decoder use the outputs corresponding with 0-256k and...

    Yes, but of course that doesn't mean all of them did. And this is where you're going to have to bite the bullet and suss out exactly how the memory addressing circuitry on your machine works because,...

    I'm sure it helps a lot if you're still running a physical disk drive, yeah. With an XT-IDE/CF, not so much. (I was kind of shocked when I did benchmarks that revealed essentially no speed difference...

    EISA also inherited the original 5170 card height specification, and probably since it was considered a "high-end" solution EISA cards are often, if not usually, too tall to fit in XT-height cases....

    In principle you could definitely do that; if you broke code modules into 16k or smaller chunks and structured the software so it'd make a call to the EMS driver to swap code and data pages in and...

    There's still the ALR machine, and the point remains that machines that we'd call "Baby ATs" and in fact have more common with what the term came to mean later existed before the 5162 even became...

    GeoWorks is actually kind of impressive on my highly-modded 1000 HX with a VGA card, but I have reservations recommending it with the standard CGA driver. It's not easy to look at. I don't *think*...

    I think it's pretty obvious that IBM would never write that down in a manual, so, no. But I'm pretty sure it's a conclusion that appeared in more than one contemporary magazine at the time.

    It's a stale memory, but I believe the soft power control in old Macintoshes is also a pull-up instead of a pull-down, so it's definitely a thing people did.
