Laptop motherboard with a 486DX CPU

An Intel 486DX CPU

Capacitors, sigh...

So, guess what I'm going to be up to if I can clear my workbench to make room?

Pulled out a noisy #486dx system in my collection! Listen to that hard drive! #oldcomputer #retrocomputer #intel486 #dos #msdos #plopbootloader #vintagecomputer #retrocomputing #90s #90snostalgia

So here's part 3 of the Unisys CWP4663 refurb project. Windows and DOS shenanigans are afoot! As usual, link in reply!

So here's part 2 of my Unisys CWP4663 refurbish project! It's a long one, but includes a teardown, RIFA goodness, and obligatory DOOM! Link, of course, in reply below.

Almost done! Software-related shenanigans next!

Yes, the optical drive is gray. It matches the power button (which is 3D printed)! It was also the only IDE drive I had that worked. Plus, many systems during this time had beige/gray aesthetics.

So, today I unbox an eBay purchase, basically a random bid I didn't even expect to win. Did I luck out, or is it junk?

And yes, you know what this is.

It works!

Now to clean, address the missing power button, get a hard drive in it, sound card, maybe more RAM, and test test test!!!

Apparently I like to be abused...

Also, janky Linux stuff.

Yes this is my original boot floppy, though I have lost the actual install media, manuals, etc. 🥲 Might still be at my dad's house...🤔

And even though this thing has abused me enough, once done maybe I'll do a Linux install on a 486? 😬

On a desk in a brightly lit basement, a very old laptop sits on a desk. It’s dark grey with a light grey keyboard. There is an early 2000s Dell tower on the floor in the background. The screen of the old laptop is black and white with a washed out image, as it’s a passive matrix screen. There is a spot of yellow-looking pixels on the left of the screen roughly in the middle, that appears to be gradually spreading. It’s causing two large horizontal lines to spread across the screen. This is gradual and irreversible degradation of the screen.

A closeup of the laptop screen. The light appears more washed out, and the laptop is displaying its normal boot messages, such as the CX486SLC CPU at 33MHz, Bondwell Global Limited, and 640K system RAM passed and 4MB of extended RAM passed. The yellow splotch on the screen is clearer, and has a pixelated look. The two lines stretching horizontally across the screen are also sharper.

Oh NO! Dreaded screen rot has shown up on my #intel486 #bondwell laptop… and there isn’t really anything I could’ve done to prevent it, and nothing I can really do to undo it!
