Thanks guys, the PSU might be a red herring here, even though the manual seems to indicate that 24V should be pumping out even when the PSU is isolated. I found there's a relay in the PSU that gives out the 24V when engaged (see pic). So I cracked the relay open and found it wasn't turning on at all …

Thanks Vipersan! I actually tested the replacement supply before installing it in the Toshy - I wanted to check if it was better than my busted one. 12V and 5V readings were fine, there's just no 24V. I installed it anyways and the machine runs, but still no 24V hitting the mainboard. That's why I'm …

Hey guys, I finally sourced a replacement PSU for my T5200 but get this - it has the exact same issue as my old one 😲. The manual says the yellow wire should be pumping out +24v... But it's dead on both PSUs. What are the chances!?! If anyone has any thoughts plz let me know 🤷‍♂️

Thanks Tiido, I've been compiling info on my OneNote, maybe that can help - see the Memory (RAM) section: https://1drv.ms/u/s!AlE-uu5DK9rJgbEPo2a7bQNpknps6A?e=uaaf5N I believe the ones I have in my machine are 1MB, but 2MB appear most common. That being said, it's hard to find ANY RAM to buy, except …

Hey Tiido, would you consider doing 40-pin SIMMs? They're basically impossible to find. They're used in Toshiba T5200, T8500 and Acer 730C machines. There's a pinout here: https://old.pinouts.ru/Memory/simm_40pin_pinout.shtml IanB on Vogons also made a mod to use 72-Pin SIMMs in a 40-pin slot, but …

Hi OP - to answer your original question: yes, of course - I would love a raspberry pi-type box that could run DOS/games etc. Maybe something like Retro Pi, eg HDMI out, USB ports (for wireless mouse/keyboard), SD Card, sound. I'm not hardcore like some of the guys here, but I'm sure many outside of …

In an attempt to quieten the fans and give them 6V instead of the 12V from the PSU connector, I shorted out 2x 12V PSU fan connectors 😱(they're dead) so I'm now running 3x 12V fans in parallel from the single left-side fan connector. I opened up the PSU but can't see any obvious issues, so for now …

@djrm- welcome! Your adapter is a cool idea, especially putting on a board like that. While I've made some progress with my rig, it hasn't been smooth sailing. The good: I threw in an ISA sound card, and used UNISOUND (from a fellow vogon'er) to get it working easily I ripped a small PC speaker out …

Mate, just wanna say THANK YOU! I owe you a beer! Just bought an ESS688 card and was in struggle-town. I tried multiple drivers, IRQs, autoexec.bat/config.sys files, the lot! Ran UNISOUND.COM and BOOM, all sorted! It's a silver bullet for me! 🎮 Success story on a 386 Toshiba T5200 and ESS688 ISA …

OK so I fixed my CMOS clock (RTC) with a new CR2032 battery and diode based on advice from others on the forum. I imagine this "mod" would apply to almost any system with a 3V RTC. Here's some pics to help others: https://lh3.googleusercontent.com/kg8JcWeLI_Wa0zVEzr2O_ …

Hi, hoping a Toshiba or display expert can assist me. Looks like I broke something when I took my Toshiba T5200 apart. The screen is missing the top and bottom horizontal parts and the text is a bit distorted. Was working fine previously. I've tried the usual re-seating of connectors etc. Also, CRT …

@my03 - I haven't decided yet on the fan replacements, lots of "silent" ones on ebay but the postage is gonna take forever. Will keep you guys updated. As much as I love the authentic 100MB HDD, pretty sure the drone sound of it is giving me headaches so I might end up swapping it out. BIOS flashing …

Hi all, a new member of the T5200 club here! As a kid I cut my teeth on a T3100/20 that I was given (my first PC - when everyone else had Pentiums!) , including DOS commands and some QBasic. Anyways after researching the T5200 recently I thought it was more practical and found one on ebay, and I've …
