@@laserhawk64 "Murphy’s Law is a humorous American axiom that states anything that can go wrong, will go wrong. The term Murphy’s Law was coined in the early 1950s during G-force tests by the American Air Force. One version of the story says that an aerospace engineer named Captain Edward A. Murphy installed a key sensor backwards, skewing the test results. Another version of the story states that Captain Murphy did no such thing, that the reason he is associated with Murphy’s Law is that he frequently expressed the idea that anything that can go wrong will go wrong. Eventually, other members of the team began to refer to this sentiment as Murphy’s Law. A third version of the story comes from John Glenn, stating that Murphy was a character in Navy educational cartoons cast as an incompetent mechanic, leading to the idea of Murphy’s Law. Murphy’s Law is by far the most popular of the humorous laws dealing with things that go wrong. Sod’s Law is a British axiom that is somewhat similar to Murphy’s Law, but with a twist. Sod’s Law carries a sense of being mocked by fate. Sod’s Law is related to the idea of the unlucky sod, an average person who has bad luck. Sod’s Law first appears in the 1970s. Finagle’s Law is Murphy’s Law with an addendum, it states that anything that can go wrong will, and at the worst possible time. The term Finagle’s Law was coined by John Campbell Jr., the editor of Astounding Science Fiction in the 1940s through 1960s."

I restore TRS 80 machines. I've done several full restores on Model 1s, Model 3s, and Model 4s. I haven't had anybody ask me to restore a Model II/16, but if the other three systems are any indication, TRS-80s are basically just like this. You fix one thing, and something else breaks. So you fix that, and something else breaks. When you restore a TRS-80, the algorithm seems to be: 1) Try to boot and observe symptoms. 2) Take apart, get a schematic, identify likely candidates for problems, replace components. 3) Go back to step 1. This loop continues until *eventually* the problems are sorted and you can break out of step 1. The disk drives in particular seem *super* finicky. Once you get one working, you just automatically start devising all kinds of voodoo superstitions and behaviors hoping to keep it working.

Curious that the internal design is so bad. This machine originally sold for $3450 in 1980. Which was a hell of a lot of money back then for an 8 bit machine. Compare that to the Apple II which sold for $1298 in 1977. Or compare it to the IBM 5150 in 1981, which sold for $1565. It's not an entirely fair comparison, since the Apple II didn't include a disk drive or monitor, and the 5150 didn't include a monitor. But $3450 was still a LOT of money for a Z-80 machine. Probably the more direct comparison was the Osborne 1, which was also a Z80 machine with built in disk drive, monitor, and a detachable keyboard that sold for $1795. So the TRS-80 II was a strange outlier that was crazily overpriced. Oddly, I think the high price may partially explain the bad internal design. When you design something to be cheap, it has to be inexpensive to put together. That means the designers have to put more initial work into it to make it easy to produce. The same isn't true when the thing can sell for a high price. You don't really have to put a lot of thought into how it's put together. I can't imagine how much time it took to assemble these things in the factory!

I remember reading in Radio Shack catalogs that they sold a 5MB hard drive (a giant 12" monstrosity) for the II/12/16 series of computers. I don't know if it used that floppy controller port or if it used a new port via an additional card in the cage. If you ever run across one of these (or even just information about them), it would be a great addition to this series. I haven't yet gotten all the way through the series, but if you haven't already mentioned it, I find it interesting that the II/12/16 systems could actually run UNIX. Radio Shack sold "Xenix" for these. I assume the hard drive expansion and lots of memory expansion was required for that. I also remember reading (in the catalogs) that you could connect serial terminals to each of the serial ports and let three users all log in at once. Way way ahead of its time, and incredibly impressive for a Z80-based computer. (Correction: It seems that Xenix requires the 68000 processor board. I think that was an option in the II/12 but was standard in the 16. Still way ahead of its time, but something you won't be able to try out on your II as it currently exists.)

Somehow the executable file had been deleted from the (original!) disk. Every other file was present and seemed to be okay (as far as I could tell with my very limited knowledge and tools at the time), but I had to way to run the program. Eventually I found a friend who also had the game and I tried copying the executable from his disk, but he must have had a different revision or something; the file was too big to fit. That's the only time I ever lost data from power cycling the PC, but I've been skittish about it ever since, and I always make sure to unmount USB drives before removing them, even when I "know" it's not always necessary.

The solenoid only lifts the head load pad from the floppy. The head is still in contact with the floppy and the power on/off pulses can still "write" to the disk. If the head load pad is worn or missing the drive may have issues reading the floppy although the FDC would usually retry several times. I suspect possible dirty contacts on the backplane.

Dragging on is fine, it reflects real world senarios. Unless you are a (in this case, a TRS80) fanatic, its also fine to break up these sort of video series. Variety is the spice of life (or so they say). Keep plugging away at this one, it will be worth it in the end, and it also supplies more specific solutions for those trying to do research or diagnostics in the future.
