  1. After coming back from #VCFEast2026 I felt a little bad about neglecting my #IBM5150 restoration project. So I spent some time buying some replacement chips. Hopefully I’ll be able to a diagnostic ROM running to help locate the bad RAM in bank 0.

  6. 💻🤔 Oh, the 12-minute saga of PC compatibility! Apparently, if your device can't time travel back to 1981 and run IBM 5150 software, you're doing it wrong. Who knew the secret to modern tech was being able to impress a computer museum? 🙄🔧

  7. For the final day of #DOScember 2025 I give you part 4 of my #IBM5150 restoration video series. With lots of help from the community, I try to trace down what IC(s) are keeping my IBM 5150 from booting.

    The IBM 5150 will return in 2026 for Part 5!

    Happy Jank-tastic New Year!

  12. Something seems off with the AMD 8088 CPU at U3 on my #IBM5150 that I am trying to restore for #DOScember.

    Pin 22 Ready should go HIGH when the CPU is ready to start executing code. The view on the oscilloscope shows high then low. Not good.

  17. 🎥 New #IBM5150 Video Drop 🎞️

    In Part 3 of my IBM 5150 restoration series for #DOScember, I check for the 4.77MHz clock signal on the motherboard and give it an ultrasonic bath.

    (Sorry about the choppy audio, not sure what went wrong.)

  18. Well, I had the dip switches set incorrectly and it was trying to test memory that didn't exist. Fixed that and the floppy drives seem to work as well...

    I'm also impressed that the Dell System 200 DOS 3.3 Master disk (circa 1987) is still working.

  19. #DOScember Video Drop

    As a surprise follow up to my #IBM5150 restoration series Part 2, I made a short video of a power on test waiting for a few minutes to see if Big Blue makes a beep.

  20. 📣 New Video Drop 🎞️

    Who has time for #SNF?! There's new #DOScember holiday hijinks to be had!

    In Part 2 of my #IBM5150 repair series I start poking around the motherboard looking for trouble. Check out the full video in the link below!

    🎅🏼 Merry Jankmas! 🎄☕️🍪

  21. Working on an #IBM5150 for #DOScember. Following troubleshooting guide on MinusZeroDegrees.net. PSU seems good (stays on when plugged into board), but no beep code from speaker.

    Does the T1 Trimmer look ok? It could be broken as mine doesn’t look like the one in photos online.

    No obvious damage, no exploding caps, and voltages look good coming off PSU at P8 & P9 connectors.

    This year for DOScember I give you the gift of me fumbling around inside an #IBM5150 PC as I try to restore it to working condition all month long.

  23. It’s almost time for #DOScember … I’ll be working on my first #IBM5150.

    Actually, I don’t know what I’m doing, so maybe I should call it:

    #TheMostJanktasticTimeOfTheYear or
    #DOSJankember or
    #ADOScemberToRemeber

    🤔🎄☃️👨🏻‍💻

  24. Before I get started on #DOScember hijinks, I need to verify that my #IBM5150 PSU is safe to use.

    Looking for help from my #RetroComputing and #VintageComputing friends who know more about this than I do.

    It’s never too early to start getting ready for #DOScember! Join me as I unbox and check out the latest addition to my #VintageComputing collection, an #IBM 5150 and it’s glorious Model F keyboard!

  27. I know I’m not even close to finishing my restoration of a #MacClassic, but is it too early to be thinking about #DOScember ?

    I may have “accidentally” purchased an #IBM5150 for some holiday cheer.

  28. I'm lucky enough to have my very own computer museum in my home office, with many of the computers I used in my youth from an #IBM5150 PC to home computers like the Sinclair #ZXSpectrum and handheld PDAs from #Psion windows.do/my-computer-museum/

  31. Excellent and fascinating presentation detailing exactly how the demo "Area 5150" completely smashes the limits of IBMs terrible underpowered crappy home computer from the early 80s...

  32. It's only after I rekindled my interest in old computers 5-6 years ago that I eventually learned that CGA was a lot more capable than I believed back in the day. Some of the demos on IBM 5150 PCs with the original CGA adapter are impressive.

  33. Today in “Things I don’t understand”™️ we have “how to figure out if my IBM 5150 has access to all its RAM”, “how to interpret the manual clarifying the dip switch positions on the motherboard”, and “how to get the Hercules video card to display graphics”.

    Granted, electronic #RetroComputing is quite new to me, but this has me feeling like a complete dunce. Otherwise, I like the #IBM5150 / #IBMPC / #IBMPersonalComputer quite well.
