  1. A question for retro tech bros:

    My employer is still using an OKI dot matrix printer, model Microline 620, and an Epson dot matrix printer, model FX-890.

    The OKI printer is not working, and the FX-890 will only print some screens, but not all.

    It's an older Windows system, but I'm not sure which one, might be XPS.

    In the "available printer list" all of the printer statuses are "idle", nothing in que.

    What can be done to get Windows communicating again with the dot matrix printers?

    TIA.

  2. Behold the revolutionary #Chafa, where 21st-century #tech meets the artistic flair of a 1980s dot matrix printer. 🎨✨ Get ready to squint in awe at "reasonable approximations" of images, because who needs high-res when you have ANSI X3.64? 🙄🤦‍♂️

  5. I've got this vintage #Centronics to #Atari #SIO connector. The last time I tried it (last year sometime), I could LPRINT a line from BASIC, but line endings weren't correctly interpreted. (Unsurprising; Atari uses $9B as its line ending.)

    Coming back to it today to see if the adapter was configured to interpret line endings correctly, I mostly got timeout errors in BASIC and twice only, some garbage, while trying to print.

    (Printing via the parallel port on a Thinkpad 760CD running Windows NT4 works perfectly. So it's not the printer.)

    Any tips on how to proceed further with troubleshooting this connector?

  6. We take so much for granted now. In 1982, you would have to fork over the cost of a new Nissan Sentra just to type the same letters you can type now with any e-waste dumpster laptop made in the last 20 years, a $50 inkjet printer, and an office suite you can download for free. But would you look as cool doing it? I would definitely love that #trs80 and the #dotmatrix printer for my collection. #retrocomputers #retrocomputing #radioshack #8bit #z80 #tandy #scripsit

  8. I totally just bought a dot matrix printer with intent to bring into my office at work. Can't wait to hear my coworkers' reaction when I print something. Hell, I should bring in my IBM 5155 for bonus effect.

    EDIT: Know what else this printer doesn't have? en.wikipedia.org/wiki/Printer_

  9. Playing around with simulating old school dot matrix (and impact printer!) printer paper with the perforations and the registration holes and everything. #CSS #HTML #DotMatrix codepen.io/artlung/pen/ZYYNJOx

  10. Also delivered were two wide-format dot matrix tractor feed printers!

    These things are in rough shape: the foam padding is crumbling to dust, there's metal plating flaking off the rods, and they're just generally full of dust and debris and undoubtedly spider eggs. My relative insists that they work, though. When pressed, they explained that they worked perfectly thirty or forty years ago.

    [Edit: forgot to add the pictures.]

  11. J'ai réparé mon imprimante matricielle ! 🎉
    C'est une Star LC-10, elle imprimait un début de ligne et le chariot se bloquait avant que l'imprimante ne se mette en erreur.
    J'ai vérifié l'alimentation, la commande du moteur du chariot, RAS.
    Au final c'était un problème mécanique, j'ai graissé les éléments mobiles du chariot et j'ai fait tourner le ruban encreur dans sa cartouche avec une visseuse électrique, et ça m'a l'air bon maintenant !
    Testé avec mon #Atari Mega STE et le traitement de texte Papyrus (et pas la bonne fonte!)

  12. Specifications for the Epson LX-80 dot matrix printer from its manual. In 1984 these were fairly typical for 9 pin printers, though things like Near Letter Quality mode were less common (a mode that increased the effective resolution of each character: normal mode characters had to fit in a 8x9 grid, while NLQ characters had a denser 12x18 grid for the same size - this allowed 9 pin printers to stay relevant a bit longer though at the cost of printing speed).

  13. Why buy boring white paper when you could have glorious dull pastels reminiscent of the wardrobe choices of Miami Vice? Also, look at that font! Perfect 80s vibes.

    My banners are going to look totally rad.

  14. Well, internal test works - ribbon is pretty much dead but that was to be expected. Still, it sounds pretty good now. Will try to revive the ribbon.

    Warning: might be loud.

    Edit: Connected it to my Apple IIe's parallel printer card later on and I was able to print from BASIC. So it works.

  17. So, the #purists #claim "it's not the same without a real disk drive - the sound and the haptics ..." when it comes to #FloppyDisks and #DiskDrives and they're probably right.

    But did you ever notice that this purism seems to be fixed on rotating disk media only.

    I mean, no one ever says "it's not the same without loading from tape - the sound, the haptics, the endless waiting ..." or "it's not the same without 9 pin #DotMatrix #Printers - the noise, the paper jams ..."

    think about it ... 🤔​

  18. Part 3 of the StyloBot Release Series is up.

    mostlylucid.net/blog/stylobot-

    This one is less about bots and more about the reality of long-running .NET based systems: everything that learns from traffic eventually accumulates.

    Came from one of my periodic reliability reviews where StyloBot’s vector layer had drifted to 13GB on the .NET Large Object Heap due to the wrong abstraction (in-process HNSW behaving like an unbounded cache).

    The interesting part wasn’t the fix. It was recognising that the architecture itself was wrong for the runtime pattern.

    Covers:

    how I periodically review long-running services

    using dotnet-counters, dotMemory and dotTrace to find growth

    why “just add a cap” is often the wrong answer

    replacing unbounded ANN structures with bounded hot caches + compacted persistence

    taking the vector layer from 13GB LOH to <6MB

    The broader point applies to any system that “remembers”:

    bot detection, fraud scoring, recommendations, anomaly detection, RAG pipelines, adaptive systems.

    Fix the shape, not the symptom.

  20. I have just published packages for , , , and -cli, for .

    Previously packaged and , and things are looking promising for developing .NET on Guix.

    I probably won't have time to test it properly until January,

    Get some errors when trying Azure CLI, so I need to look closer into that.

    is notably missing, but I'm confused about Mono Project, fork and the .NET runtime mono repository.

  21. Stary, około 23-letni, budzik Oregon Scientific niedomaga: padło podświetlenie, a odbiór #DCF77, mimo dużej anteny, nie może zakończyć się sukcesem (chyba że zawiozę budzik na wieś lub do lasu na synchronizację). Co ciekawe, dwa leżące obok malutkie Casio nowe mają żadnego problemu z odbiorem.
    Chyba trzeba kupić nowy sprzęt. Zastanawiam się nad jakimś TFA Dostman, ale szkoda jednak tego starego. Sentymenty 😀
