The Compaq Portable III hails from the 386 era — in the days before the laptop form factor was what we know today. It’s got a bit of an odd design, but a compelling one, and the keyboard is pretty nifty, too. [r0r0] found one of these old-school machines and decided it was well worth refitting it to give it some modern grunt.
The Portable III ended up scoring a mini-ITX build, with an AMD Ryzen 7 3700X and an AMD RX580 GPU. Cramming all this into the original shell took some work, like using a vertical riser to fit in the GPU. Hilariously, the RGB RAM sticks are a little bit wasted when the enclosure is closed.
For the purists out there, you’ll be relieved to know the machine’s original plasma display was dead. Thus, a larger modern LCD was fitted instead. However, [r0r0] did play around with software to emulate the plasma look just for fun.
It’s funny to think you could once score one of these proud machines for free at a swap meet.
Nice build! I was always envious of those “lunch box” form factors with amber plasma displays.
I had a Portable 386 – nice machine – expensive
Used to *love* these machines, I yearned to own one but ended up with a less cool Toshiba 386SX luggable ‘laptop’ with plasma screen (3200SX I think?)
My dad had one of these. old 386. nothing as powerful as this one ;) good times.
I did this with a Dolch V-PAC. I didn’t know if can post a link but here’s an old picture of it: https://imgur.com/gallery/MRnjY7i
Well as long as the plasma screen was dead.
Might not have been dead. Worked for Compaq in product engineering and found a problem on the Portable III that killed the display. A ribbon cable between the system and panel was terminated into a IDC connector. The ends of the cable were trimmed after the connector was added, but the conductor ends weren’t insulated. The conductor ends would short to the metallic coating on the plastics and short out signals or power. A strip of insulating tape fixed the problem.
Oh. Well I’d like to think that it simply succumbed to age because I am a sucker for a plasma display.
Screen was cracked
What did you do for the psu it looks like you just removed the internals of the old psu and put a new psu inside but how did you get the original port to still work?
