  1. Good test--and your drive/controller combination is formatting both sides of the disk to give you 180K.
  2. ISTR that the pin rows flip at some point during the transition (top becomes bottom and bottom becomes top). Just follow the traces to be sure. . .

    The first--and last, Flipper-Snapper product. . .
  4. Definitely true, @mizapf. I seem to remember there was a push back then for 320K as more reliable than the alternatives (even the IBM PC had a 320K disk formatting option), but in practice, that falsehood was very quickly put to rest and nearly every system out there was using 360K disks without issues.
  5. The original DSR for the Myarc DDCC-1 formatted to 320K,and could neither format nor read 360K disks. Later revisions would also format to 360K to compete with CorComp offerings. Atronic and BwG controllers followed the CorComp 360K mode from the start, as it had become the de facto double-density standard. Myarc originally built their cards to be compatible with the TI specification, which was 320K. The only problem there was that the TI DSDD controller card using that format was never released, and the other TI offering that used it, the Hex-Bus Floppy, wasn't released either. As Myarc was the only manufacturer that had hardware in the field supporting the standard, they had no choice but to change to conform to the rest of the market. One note, they didn't abandon the 320K format entirely, as it always remained an option with DDCC-1 cards, and it was an available formatting option on the later HFDC and the Geneve9640 Master DSR. In the case of the Geneve, the Master DSR made the 320K (and 80-track, 720K) option available to any installed floppy controller capable of double density operation. I do have one of the TI DSDD cards, one of the Hex-Bus drives, and a Myarc controller installed various systems at my house.
  6. And if the drive in the PEB is an original TI disk drive, you can only read/write to Single Sided, Single Density disks (90K). There are still a lot of PEBs out there with one of the original drives (an MPI-51 or the single-sided Shugart drives). An easy way to double your capacity in that case is to get a standard 360K 5.25 drive. It will format both sides and give you 180K with a TI controller--and if you find a CorComp, Myarc, Atronic, or BwG controller, the full 360K will now be available on that drive.
  7. I have plenty of 512K and 2M boards in stock at the moment too, so current supply isn't a problem either.
  8. I'll have to test it against my Atronics controllers (PEB and CPS-99) one of these days, as they are also close clones of the CorComp.
  9. I've got one, but I still need to connect it. . .one of my backburner hobby projects.
  10. That catalog shows me just how many more of the European TI manuals I am still missing (an I do have a lot of them). Thanks!
  11. One thing that has been assumed, but not yet explicitly said, is that the first step towards using any given disk is learning what is on that disk. A disk manager will let you catalog the disk so that you know the names of the programs on it. Many things in "PROGRAM" format are vanilla TI BASIC programs, although some BASIC programs may require the Terminal Emulator II cartridge, the Mini Memory, the Editor Assembler, or TI Extended BASIC. Other PROGRAM files may require TI LOGO, Adventure, or Tunnels of Doom cartridges. Often, the key to understanding what you need there will be hidden within the contents of the disk--and when that doesn't work, try loading with Extended BASIC first. Some folks have suggested using a Final GROM. That's a really good idea if you don't have the cartridge you need to load something, as the Final GROM will load and run almost any cartridge made for the TI. Then you just need to parse out the disks to see which program will load and execute the software on them. One other note: a disk with a program on it named "LOAD" has a special quality. If you put that disk in drive 1 and start Extended BASIC, it will find the load program, load it, and then execute it. This may help to identify a lot of the programs on some disks, as the LOAD program may give a menu of available programs or it may bootstrap into the main program on the disk.
  12. I can confirm that these case screws work great for the console and for TI cartridge cases. The story is a little different if you use the three-screw 3D-printed cartridge case designed by @acadiel. The screws for those cases need to be a little thinner--but the use of hi-lo threads is definitely recommended. I recently found some that work perfectly, so I figured they needed to be referenced in this replacement screw thread. They are #4-23 x 1/2 Phillips-head black screws. The seller has them in 100 and 1,000 quantity lots, and the price is very reasonable.
  13. I always check out the back page notes, as it lets me anticipate the joy of reading the next issue.
  14. Al wrote TIC and TASM. Here is a link to his TIC source repository on GITHUB. He put all of his remaining code up there, so if it isn't here, it doesn't exist anymore. . .
  15. I like my T56. It is a nice, solid device, and if we can convince them to add the older 25v chips (it supports the voltage, but not the chips), it will do everything the older TL866 did for us.
  16. And a steal for the low, low price of $119.95. Obviously, the seller is under the influence of some form of psychoactive substance. . .even though it does at least appear to be a non-QI motherboard.
  17. A lot of stuff back before 1980 showed up first on PDP-11 machines. The earliest text adventures were developed and used as a troubleshooting aide on them. I remember regularly putting the diagnostic pack into the hard drive of the one I used in Berlin and booting the game to give the system a thorough workout during preventive maintenance sessions.
  18. I have several of the Comprodine and Great Lakes Software titles identified in the catalog. . .
  19. String Master did make it out into the wild in limited numbers, I think I may even have a copy of it somewhere. I remember that my disk was very strange, as only the portions of the disk with programs on it were actually initialized. . .

    Does your copy include all of the expansions released on a regular basis while the program was still actively supported by J&KH? I probably need to dig my copy out to see what the release notation was.
  21. You're sending some interesting gibberish, @arcadeshopper. Norton did several games, but they actually also released a TI utility disk or two. I have to look, as I might even have one of them.
  22. Some of us will stay in newbie mode forever (like me). It comes with the territory when we age. . .welcome back to the insanity!
  23. That would be Zach Beschormer, Isellhomeszach on eBay. I think he may also be a lurker here on the forum, and he is definitely active on the Facebook TI group.
  24. It is reported as a security risk when I attempt to download it, so there may be an issue with the file. . .
