    My CF cards are between 16-512 MB, but I couldn't get any of them to boot until I used Diskpart to "cleanall" on those cards in my Win10 machine. All said, you're right, there's no point in having...

    Somebody needs to start a thread for which CF cards are known to work/not work, and whether with the ISA-CF or the XT-IDE (8-bit PIO/16-bit mux). As well as which adapters they've had good results...

    I've got a few PS/2 Wyse keyboards. They've got a decent detent, and are pretty nice to type on, especially for being rubber-dome rather than Cherry/Gromer or the buckling spring keyboards that...

    So that rounds to, what? ~$120 USD to get the batch of 250 made? If the quality's reliable, that's a really good deal. Who did you go with to get them made? There's probably other (now) defunct...

    The ones I've been getting from Digi-Key do START to loosen after a while, but after pulling it out over and over on my XT-IDE card (probably at least 20 times for testing), I ended up lifting the...

    Yeah, I think the 74LS161 should work as a drop in replacement. The F series looks to be discontinued, but that's not surprising. The LS and HCT series seem to have taken over most applications.

    The first picture looks like a cursor on an HSYNC signal that's gone way off kilter (to me anyways)

    You've already tried swapping the CPU and the 8284 from the 1000 into a known working system,...

    Did you manage to get those headers made? Adrian's latest video said you did. If so, I think everybody on this thread would be interested in getting a few.

    Are you pulling the CPU/PIC outright, or swapping them with a known working unit? Which chip number is the PIC you're pulling? I want to follow along on the schematics.

    I just thought of something. Can you run the machine with your multimeter attached to the 5v rail and make sure the voltage level doesn't drop over time?

    I'm not sure how it is on other machines, but the Tandy 1000's are able to operate the keyboard lights independently, at least for a while. When I had a blown '245 on my HX, I was able to toggle the...

    That's not a bad scope. I'm still using an old Beckman Industrial 20MHz analogue. I was fortunate enough to be able to pick up an HP 16500B from somebody at a local retro-computer meetup, but even a...

    Yeah, vanilla 1000's are common enough. There's a couple on eBay right now, but I prefer to wait till they drop to below $100. This hobby can get kinda pricey.

    What scope do you have?

    May as well. I wanted to take it apart and clean the disk heads anyways. Probably ought to find myself a 3.5" cleaning disk.

    It's backwards on my HX too. I think this is just because the drives the HX's used had the keyway on the opposite side of what we would now call "standard."

    Let us know if you find any that accept 15.7KHz on VGA, because from there, it's a simple circuit to convert the RGBi output into clear and readable 80-column 16-colour Tandy goodness!

    I've seen white lithium grease used as rail lubricant. Supposed to quiet the drive seek down quite a bit. Might also want to put a little WD-40 or 3-1 oil on the stepper motor spindles.

    I'd say about 2-3x as much. This is fine if you're card doesn't have a back panel mounting bracket, and the socket is all that's holding it in place. Then it's not going anywhere.
