27.02.2026 01:47 — 👍 7 🔁 4 💬 1 📌 0Pour one out for this one. This might be the worst Toshiba I've ever seen. Poor J3100SS
27.02.2026 00:27 — 👍 5 🔁 0 💬 1 📌 0Who knows what was installed by the previous owner. They wernt done!
22.02.2026 21:16 — 👍 0 🔁 0 💬 0 📌 0Holy shit it works. I somehow managed to fix this thing
22.02.2026 19:42 — 👍 14 🔁 0 💬 2 📌 0Next thing I had to do was fix the ribbon cable because it had been torn
22.02.2026 19:41 — 👍 4 🔁 0 💬 2 📌 0All right well time for experimentation with educated guesses on capacitor values.. let's see if the switcher comes alive
22.02.2026 19:41 — 👍 3 🔁 0 💬 1 📌 0I was hoping maybe the switching power supply circuit could clue me into the values but I can't find the IC on that one either
22.02.2026 15:30 — 👍 3 🔁 0 💬 1 📌 0Yeah this is a basket case.. someone yanked the capacitors off of the panel and I don't know what they were originally, I can't find data anywhere. The panel is a work of art though
22.02.2026 15:01 — 👍 4 🔁 0 💬 1 📌 0Unfortunately it looks like I've inherited someone else's project
22.02.2026 15:00 — 👍 3 🔁 0 💬 1 📌 0Another one fixed! The CRT is a bit weak unfortunately
21.02.2026 18:08 — 👍 21 🔁 2 💬 1 📌 0Wow... Finally something like this comes out, its nice. having a USB to IDE device that supports vintage drives is handy www.youtube.com/watch?v=XUmx...
21.02.2026 09:49 — 👍 9 🔁 0 💬 0 📌 0I feel like though if someone reverse engineers the 3.5" flux dumps, i bet a 5.25 version could be recreated.
20.02.2026 18:30 — 👍 1 🔁 0 💬 0 📌 0Oh yeah that one is nice. I was going through the book for this one, and itll give you tons of output. RPM, Azimuth error, eccentricity errors, etc.
20.02.2026 18:30 — 👍 1 🔁 0 💬 0 📌 0Dime a dozen until you get into laptops where it really matters
20.02.2026 16:28 — 👍 2 🔁 0 💬 1 📌 0Probably. First though youd have to write the flux image to disks with a known good aligned drive.

20.02.2026 13:41 — 👍 19 🔁 3 💬 3 📌 0yeah these were only released and sold in japan, I dont believe they ever made a notebook-sized plasma laptop over here except the T4400
19.02.2026 22:52 — 👍 3 🔁 0 💬 0 📌 0Sadly however, the HDD was yanked and its proprietary....
19.02.2026 22:50 — 👍 1 🔁 0 💬 1 📌 0I got yet another cool toy. Toshiba notebook that has a plasma display panel!
19.02.2026 22:50 — 👍 57 🔁 4 💬 4 📌 0This is hilarious 😂
17.02.2026 13:03 — 👍 11 🔁 0 💬 1 📌 0I wish I had the insides. Only the board and power supply was shipped to me for repair
16.02.2026 10:08 — 👍 3 🔁 0 💬 1 📌 0They're fairly common but they also vary so you'd have to look at your specific board unfortunately
16.02.2026 02:48 — 👍 0 🔁 0 💬 1 📌 0Fixed another machine today! An XT clone, branded as an EDS. Needed all the tantalums replaced and RIFAs pulled

16.02.2026 01:00 — 👍 3 🔁 0 💬 0 📌 0Yeah he's just waiting for the right moment. The costs came down from China and it's astronomical, so roi has to be determined
14.02.2026 12:00 — 👍 2 🔁 0 💬 0 📌 0Yep they absolutely are, even when new. I made a mechanical version that works fine and even redesigned it to use a slightly more modern keyswitch, but i sold the design to MacEffects.
14.02.2026 02:37 — 👍 5 🔁 0 💬 1 📌 0This one has a 230 board as well! The original 210 board has a bad SC chip, preventing full system initialization.
14.02.2026 02:21 — 👍 1 🔁 0 💬 0 📌 0Finally fixed the PowerBook Duo! Wouldn't spin the HDD or boot, and turns out a MOSFET actually went open! I haven't encountered that one before, and it wasn't a visible fault either.
