I like the "marble" look to the keys. Super cool.

What happened to your keys is the original outer gloss/protective layer of the keys was removed in the retrobrite which led to exposed raw plastic being exposed to air, so the exposed underplastic oxidized. It usually can be neutralized/prevented by giving the keys/plastic a nice alcohol wash after the retrobrite then immediately rub some petroleum jelly or soak in some mineral oil for a while to allow the exposed raw plastic to absorb some of the oil. So you may want to attempt retrobriting a key for a short time just to remove the marbled pattern, then quickly give a alcohol bath, and immediately coat in petroleum jelly or dip into mineral oil for a good 15-30 min, then you should be good to go..

Am I the only one who finds these videos really relaxing to watch? It's so satisfying to see it get repaired and cleaned.

Always been enjoying your videos so much! keep your passion going!! :-)

Those are some trippy-looking keys now! Looking forward to part two, since the internals can be a real "fun time" to deal with, especially the disk drives. Haha, my O1 still needs work after all the years I've had it. I appreciate the mention as well!

Id honestly love to see a 2+hr episode I watch these while I do my programming so... the longer the better

This was my very first computer. My wife made me give it away in the mid-90s but I had it from the early 80s and used it all the way through the early 90s (straight through college!). I had to rebuild several cables and keep it dusted, but it never failed me. In a way, I miss it, but there have been so many other, better machines in my life since then that I can't be too sad. Thanks for doing this work. It pleased me to see it.

Oh no, not the magic smoke!

Freaking love the care and respect you give these old machines.

Finally and episode where something goes boom.

I’m not even into computers at all and I found myself watching your videos for an hour... great job editing and explaining your steps... makes me want to pull apart my old Atari and give it a good cleaning...

I like the marbling effect on the keys post reassembly, to be honest...

I think I may know a fix for the marbled Keyboard. I don't know if it's for the same reasons but sometimes I see such discoloration on plastic inside my car after some rain drops fall on it through the open window as well as on the bottom of my air washer. The fix for that is Petroleum Jelly or Mineral oil. After applying some to the discolorated area and then wiping off the excess[the plastic appears to absorb it so the surface is not sticky even without washing, which could cause it to discolor again] the white color fades and the plastic is back to normal. You could try it on one key, and if it doesn't work you can just wipe and wash it off. tl;dr Try to coat the keys with Petroleum Jelly or mineral oil.

Is it just me, or are your studio shots slightly pink?

My dad used to do this stuff for a living. He even taught himself to program on a Commodore 64. I think that's why I'm so intrigued by these videos. Lol That and the restoration process is very satisfying.

"definitely different than they did before." - The 8-bit Guy I like that I'm taking that lol.

My dad was employee 27 at Osborne. We used to have a few at home and it was the first computer that I learned to program in BASIC on. Hope that you have more luck with the rest of the restore, really looking forward to part 2

I love these old portable computers!!!!!

Dude, the feel of your intro tune takes me right back to those 80's sitcoms that we all know and love. Great work; so well made. I often click on the videos just to hear the intro!

Another great vid, and what a treasure of a computer! Every time you do a restoration I learn something new. Can't wait for Part Two!

You had a real uxwbill "Smoke Test!" moment there.

I miss the clicky sounds of the keyboard in the intro :(

Can't wait for part 2! Love your restoration videos, so satisfying! Keep it up David!

Anyone else think the keys kinda look cool like that?

Aww.... I wanted to see the component the magic smoke escaped from!

Received notification after 2 hours.I'm proud of you KZfaq

The marble pattern actually gives it some kind of a modern vibe. Looks cool!

1st, thank you for the nostalgia and care you take with these classics. i loved my C64 as a kid. 2nd, you are an excellent presenter. Very professional speaker. Love watching your show

I just started watching you videos today I love them I’m obsessed with tech restoration videos of yours bye

i love this tipe of video!

This is definitely your best restoration video you've ever made!! Love the channel

The intro for this Osborne serious is super sick! It's so up-beat and poppy, reminds me of classic synth from the 80's/90's! FABULOUS!

*sees The 8-Bit Guy uploaded new video* - me: YAAAY!

David: -Plugs in the Osborne- The Osborne: “KRAKATOA!!!!!!”

I really admire your dedication to 8 bit restoration. I remember a co-worker that bought an Osborne 1 about 1981-82. I thought that was so cool. A portable computer. Amazing.

How good he is at fixing this stuff it's unbelievable I love it

Is that a Weyland-Yutani Osborne 1?

Swirls in the plastic might be where some of the bromine mixed into the plastic irregularly. I know when I was a plastic mold injection operator we could get color swirls in plastic parts if the mixing speed wasn't fast enough. Also nice find on the Osborne 1.

You're one of those few tech channels that don't bore me to death. Nice video.

I'm glad to see the channel grow. I love your videos, keep up the good work!

I love the intro! You should do more restorations!

Noo you didn't show us what caused the fire! :(

It doesn’t feel that long ago that I was waiting every day for the next part to come out. It feels like last week but it’s been about a year now. I guess I have known this channel longer than I thought!

Loved the audio while you were narrating. It was cool to hear everything as you took it apart/put it together.

"The tried and true method." Literally the worst retrobrite experience on the whole channel.

On using the White Lithium Grease, thats a metal-on-metal lubricant, and I would definitely go out of my way to avoid using that on plastics, especially older plastics. WLG is going to use a combination of mineral oil and paraffin as its lubricant base, and who knows what else, and it can react with and degrade plastics. Its also not the most stable of greases, and the lubricants can separate from the lithium thickener after not too long, which just leaves things messy. For plastics I recommend sticking with silicone greases. I'm not sure the best spray silicone, but I've had good success with the only one I've tried, WD-40 brand. The best silicone grease I know of is 'Super Lube Silicone Lubricating Compound', and I would highly recommend that as your primary plastics lubricant. Its also waterproof, dielectric, and its still appropriate for low pressure metal on metal applications.

These videos are so cathartic. Thank you!

Thank you so much for the years of education and entertaining content, David. You're the best!!!

I had a similar thing happen with some old calculator keys when retrobrighting. I found that the best way to get the streaks out is to let the plastic "eat" some oil. Wd-40 soaking was the best thing i found. It seems that the plastic gets dry when bleaching and needs to connect with it's petrolium roots to even out the color.

"gizmo" "went to town" Texas! I love it.

The reason why I love this guy is the restoration video is the best with him explaining what is the problem and explain how he will do it and that soothing voice

man, I really love your channel, keep up the good work!

When you're stood still talking about it the camera has a pinkish tint. It's pretty dope, you should do that to the other ones too (but maybe not as extreme)

The keys actualy look kinda cool imo :D

I like all your videos, but I love your restoration ones! Thank you for sharing.

I love your restorations. Looking forward to see more!

Thumbs up every time I hear the opening tune!!!

You've cut this episode a bit too short tbh, some parts are far too quickly shown. Please go back to your old style, I love longer episodes :)

Awesome work! I love seeing an old machine get some cleaning done.

I love history. I love keeping it alive. You take it and polish it up. Instant subscribe.

1:36 Damn I even have the feeling of smelling that smoke. What kind of black magic it is lol I'm the only one?

Those keys actually look pretty cool

Nice work on a frustrating restoration job. Looking forward to part 2!

Looks way better. Awesome work.

Ozzy Osbourne got a computer.

I'm suspecting what happened to the keys was that the difference in contact with the wrap made some parts have more hydrogen peroxide on them, which led to some reaction with the plastic. The same thing happened with the cover, but it was far less noticeable as the cover, being a plain big piece of plastic, is a lot easier to even the contact of the wrap, opposite to the keys which are small pieces of plastic spread out. I suspect the temperature outside had to do with it as well, as apparently those marks appeared when they started to get colder.

I have to say these are my favorite videos of yours. Very thorough and well presented. I also recommend the Computer Chronicles video on entrepreneurs as Osborne is featured in that episode. I may well attempt to restore a Compaq Portable due to inspiration from these!

Sweet, another retro-bright episode. My favorite.

5:58 That bent pin is killing me!

That "marble" pattern is very similar to the results I got with my yellowed Super Famicom (I used your method)... I think it has something to do with the heat: As the hydrogen peroxide begins to evaporate, it begins to "bleach" the plastic (parts become too white), making that bizarre effect. That's why I would avoid retrobrighting when it's too hot. (the super famicom was my first attempt, and since then I didn't really need yet to retrobright stuff so this last part is just a guess)

Can't wait for part 2, Excited

Great video. Really love that opening tune.

You might want to try rubbing some olive oil into the keys to see if it mitigates the mottling effect from the H2O2. Not sure if it will help, but it has helped me with similar issues on vintage SGI workstations.

I think Marbled looks better than yellow

Can't wait for part 2! This is one of the few retro computers between yours and LGR's channel I've actually seen. I knew a guy who owned 2 of these, and only one worked. He said it took 20 minutes to boot, but I think he was just pulling my leg.

I used one of these briefly back in the day. Always loved its smell and the disk noises it made.

As a Osborne owner myself, my heart sank when I saw the magic blue smoke. I hope you do get it working--they're very interesting machines. And I'm worried about the keys. Do you have any idea on how the marbling happened?

never clicked to new video that fast :D

The mat on the keyboard is so handy. It prevents dirt and grime from building up.

9:09 holy crap what a difference! I had no idea you could restore the old plastic! Great job.

I actually really like the marbled streaks, I want keys like that.

1:35 Really scared me more than it should have.

Really liking these new in and outros

I love rewatching these videos.

Idk, the marbling makes it look like some kind of executive edition hah! Pretty cool.

Your white balance is off. At least in the first clip.

I like your restoration videos a lot. Very cool stuff!!

I love the colouring on the keys! It looks fancy! I want one like that!!

The keys look kind of neat, like granite or marble.

try car wax to remove the marble effect

I love your vintage conputer restorations! :)

I was born in '95. I have little-to-no idea how a motherboard works (I assume its by magic). I'm afraid to even look at a soldering iron... and yet, here I am. Watching this man restore computers. It's soothing in a strange way... like Bob Ross or The New Yankee Workshop. Kudos!

This episode is a bit too short but still enjoyable nonetheless

A computer and a smoke machine coooooooool

This new intro is so cool! 👌🏼

What an amazing video project and layout for all audiences to watch.

I wish I could have keys that look like that

Smoke Test! KABOOM!

these videos are always so satisfying and i dont know why

I want to do restorations and repairs just like you do. It's amazingly satisfying to watch you work.
