    Many places that stock that chip often have years or decades old stock, hence "new-old stock". Dallas Semiconductor has been defunct since 2001, being bought out by Maxim Integrated. Anything that...

    The numbers I gave are examples of common types I usually see, but they can come in other sizes as well. If you measured 5x15, then you can look for those dimensions. You can also substitute another...

    The Tandy 1000 series had several different video systems depending on the model.

    There's no reason to use ABS, PLA or PETG will work fine.

    Standard canned air dusters are cheaper, you can freeze stuff by inverting them and spraying the liquid out.

    I can buy four large cans at the local Walmart for $10

    20ns SRAM is good up to 50 MHz, so you can run basically any CPU available on the 486 platform without problems, even the DX 50, assuming everything can tolerate the 50 MHz bus.

    The problem is nozzle size. You can print medium to large gears on FDM printers fine, but if you want to print tiny gears, you need a much smaller nozzle. Most FDM printers come with 0.4mm nozzles,...

    Power supplies are not complicated, especially ancient ones from the 386 era. They're almost always silk screened with part designations on the PCB, so all you have to do is write the designation...

    If it can't be repaired, then you can often shove the guts of another power supply inside. MicroATX power supplies fit in most anything that isn't a small form factor box. You just gotta work out new...

    When you're a home hobbyist, it's not practical or often even possible to drop a grand on one tool. If you've never tried one of these units, don't automatically condemn them because they're a tenth...

    Those things are junk. They get clogged constantly, sometimes break in half from the spring shock and often rip traces off the board from the high vacuum. Not to mention the smell when you inevitably...

    You should verify if the chips are the correct type and if you have TAG RAM installed. Cache won't work without TAG chips, usually there's at least one, sometimes two.

    No, the ProFile hard drive used the parallel port and the drive itself was proprietary, being a standard ST-506 drive with a custom Apple controller board.

    Get rid of that barrel battery on the 386 board or you're going to have a bad time.

    Try a utility like Mt. Everything or SCSI Probe to see if the machine can see the drives. Older versions of Mac OS without PC Exchange can't work with non-Apple formatted disks, so you'll need to...

    Tadiran is one of the better battery manufacturers, or used to be. They're an Israeli company and all of their batteries were made there at one point. While I'm pretty sure they're still in business,...

    When did I say they were hard to find?

    A ten pack for $11, or just over 90 cents per disc is about quadruple what they should be.

    CD-RWs and optical media in general is more expensive now than it was 10-15 years ago, unless you find a derelict old pile in a second hand store. Less of it is being made, people hardly use them...

    If it weren't 1200 miles away, I'd go for the Mac SE FDHD. The one I bought here a few months ago is junk, it'd help me make one good one from two units.

    The "TE11256-20K" DIP ICs are SRAM cache chips. I'm not able to find any datasheets on them, but there are a few places where you can still buy old stock of them, so they're probably real. Whether...

    If the CRT is powered, it should always have the heater glowing in the neck. If there is no glow, then the CRT is not getting power on the neck. There's a brightness control knob on the bottom front...

    If we had a picture of the board, we'd be able to tell immediately if the cache chips were fake or not.
