In 1983, Compaq shocked the personal computer world with the release of their first product: The Compaq Portable. An IBM-compatible machine that you could carry around with you. It was a major success, and put Compaq on the map for years to come. Today's video documents my experience with trying to get one of these machines found in the trash working again!

If anyone is interested in learning more about Compaq's history, I'd highly recommend the documentary "Silicon Cowboys". I did a brief retrospective at the beginning of this video, but there's a lot more to the story and its worth a watch.

as a certified Compaq repair tech from the 1990's you did good with your limited resources.. the wire on the back is from Compaq do not mess with it.. your cap idea is possible another thing you can do is ground yourself (i.e. ground strap or touch metal chassis while working) carefully remove all socketed IC chips then plug only the motherboard into the PSU and power on and see if you get a steady LED... i would suggest giving a try to fix the motherboard..could be a good learning experience and worse case you will need to source a new board...

Worth mentioning about that bodge wire at the end is that's a common thing to find. Sometimes the manufacturer finds an issue with a board layout but determines a patch wire is more cost effective to install than to remap the whole board for production. Given how tidy the wire placement is, I'd almost put money on that being from the factory. Given the state of the motherboard, it's at least a reasonable time to get the supplies for soldering in the process of getting it running. If you end up getting it running, so much the better, but if it still doesn't work then sourcing a replacement board isn't bad, either, since that allows more part swapping in the future.

I remember those Kalok hard drives, and what was referred to was the Ping of death with the actuator Motors.

For anybody who doesn't know, retro bright is a chemical compound that removes the top layer of the yellowed plastic, to reveal the non-yellowed layer beneath. Magic erasers are made from a very hard material called melamine, but in a foam state. So basically magic erasers are a very fine sandpaper. So using them to unyellow plastic would also remove the top layer of the plastic. Both retro bright and magic erasers thin out the plastic and can only make them more fragile. If you care about the longevity of your yellowed devices, don't use either. Do what you will with this information. Personally, I hate ugly yellowed plastics, but I hate dealing with broken or fragile plastics more.

People throwing out valuable things isn't anything new, although it is surprising every time. About 2 years ago I found a 2011 MacBook Air next to the trash bin in a working state. I need to mention, in my country, any Apple product is considered reserved for the richest people only. Someone threw it out because the battery was bulging - I know, a fire hazard, but all of the other components were undamaged. I replaced the battery for $90 and sold it online for $300 in a perfect working state and almost perfect visual state. One man's trash is another man's treasure.

my choices were sended it to this guy or let it rot in my house because I do not remotely have the skills necessary to fix something like this. I figured it had a better home in Michael's collection.

Wow this is a very deep dive into this video. Thank you for teaching some things to do to help clean the plastic on my Apple II Plus!

You could actually just try to use the adaptor and the shorted cap will blow up so you know wich one it is. But its kinda risky cause idk how strong the traces are

I blew a trace out on my VDU. 8-bit guy blew a hole through his motherboard.I actually did check the caps on the VDU before I powered it on, which is why I got surprised when it exploded in my face; it wasn't a dead short. But yeah, that's the surefire way to find it :)

Ah yes, Tantalum capacitors, breaking vintage computers since the 80s. Adrian from Adrian's Digital Basement has made a couple of videos diagnosing and replacing capacitors on vintage computers, you might want to get in touch with him, Shelby from Tech Tangents or really any other retro tech repair KZfaqr to get the motherboard sorted out, It's definitively cheaper (and easier) than finding a working one on eBay.

Hope you figure out what's going on with this machine. Consider a collab with LRG, Ncommander, the 8bit guy and Enderman. Wish I still had my 1st computer around so I could do something like this for fun.

Highly recommend looking for any tantalum capacitors that may have shorted. It's a common failure mode for older

Looks like the quickest way to find the bad cap would be to use the ATX adapter and let the smoke out!

I know you're referring to it as magic eraser, but you can order melamine foam sponges for super cheap and it's the same thing.

I used to have one of these that I put an original 10MB full height IBM drive in it from a 5160. The power supply would tend to overhead and shutdown. So I mounted a large fan to the PSU to keep it running. I later swapped to a hard card and didn't need the fan.

I can tell you really went the extra mile with the editing on this video. Also, it was fun to use my truly extensive KZfaq watch history to guess the failure points in what needed fixed. Never seen a Compaq Portable in person, but hell if I don't know what makes them tick haha

As a seasoned computer tech, I agree with Mickey Mouse Park's suggestion. Trying to source a newish Mobo for that machine may prove to be hard and pricey. I am patiently awaiting part 2.

I replaced the power supply with a standard AT PSU. I needed to use it on 240v and the original was 120v only. The replacement fits well in the space.
