    I googled up a photo of the FreHD label in question, and, well, personally I would avoid putting "Radio Shack" on it if I were selling a similar thing because the "Radio Shack" name is still a...

    “Tandy” as a corporate entity ceased to exist around the year 2000 and simply became “RadioShack”; the “TRS” in TRS-80 was specifically an acronym for “Tandy Radio Shack” and by this point they’d...

    According to the US Trademark office The registrations that contain "TRS-80" are dead. There are, however, still live registrations for "Radio Shack". So, and do not take this even remotely as sound...

    That "IC" is a 150 ohm resistor array, which should be fine. That drive goes on the end of the cable.

    The fact that the drive didn't work when it was installed in your Tandy 1000 still concerns me...

    Check the markings on said IC and see if it's actually a DIP resistor package because, yeah, that's probably it. The drive with that on it should be at the physical end of the cable furthest from the...

    And just to sanity check, you're using double density disks, not high density? That's odd, I can't think of a good reason why the drive wouldn't work unless it's actually broken.

    Pretty sure it’s standard Shugart no-twist jumper-it style, but I only say that because the Tandy 1000 is that way (unlike a normal PC clone) and it’d be a little weird if Radio Shack did anything...

    I vaguely remember you recently got a Tandy 1000 working, I think it’d be worth it, just for the heck of it, to install the Tandy 2000’s drive as drive “b” and see if you can run it through its...

    We ignored the whole Black Friday thing at my house; personally spent the non-chore/non-completely-vegetating portions of the day working out the kinks in integrating a new clock divider circuit into...

    I second either using Xlib or using some kind of “display proxy” layer in between your home brew code and the display. Likewise it’s been a long time since I even thought about it, but my...

    The 2000's drives are double-density 80-track, same as a 720k 3.5" drive, so they at least theoretically could work in a PC if properly configured. When your friend tried this in 1987 did you first...

    Do the "TED" Commodores (C16 and Plus/4) have the same serial timing issue as the C64? If they don't then I'd think a 1540 would work with a C16, but I honestly have no idea.

    So... starting from the divide by three I came up with above I hacked together a switchable divide by three/six circuit. Normally I'd think it'd make the most sense to either divide by two and use...

    That magnetic record bears an eerie resemblance to "3M Sound Page" system from the 1970's. (The latter is just "flipped"; the recording medium stays in one place while the recording head both moves...

    Maybe a little off-topic, but sometimes I use a really trash method to allow my Tandy 1000 to telnet into my Apple Macbook: I installed "socat" with Homebrew and when I want to telnet in I run this...

    People should start including sockets for these on XTIDE cards. They're easy-peasy to tack onto things like that.

    I was going to suggest Eadweard Muybridge’s work as a possible candidate, but his rigs used the Collodion process.
