I am LOVING this restoration. It's bringing back memories of computing on this thing, and seeing the internals is a treat. I think my father still has his Model I in storage. I might have to 'acquire' it.

This episode brought to you by the keys U, N and 4.

Very satisfying as always, beardy man. A suggestion: Instead of 3D printing, use Hula Hoops.

This was another awesome episode but I can't explain why the trash to treasure series is so entertaining.... They just are, i mean i'm unlikely to ever own a TRS-80 and have no yearning to acquire 1 to repair.... my zx +2, C64 and Amiga 500 & 600 are more than enough to keep me busy + my 23 video game consoles with approximately 2000 physical copy games, you could argue ive got better things to do, yet i'm still here basically watching a guy my age bringing an old computer that i'd never heard of, back to life!

Three cheers for the beardy bloke at the table.

I'm guilty of not stating it more frequently, but RetroMan's smooth voice and quality content are always a pleasure to watch. Great video!

I really like watching restoration videos of old computers along with hearing a really nice background song chosen for these kinds of videos. Great video as always, Neil! 👍🏽

Good solder job. My method for de-soldering a ribbon cable is that I'll swamp all pins with solder then I'll apply heat continuously along all the pins while tearing the ribbon off the PCB. When I'm done, I'll clean the excess solder on pads either using gravity or a solder pump.

I love the way you present these restorations. It's so calm and relaxing to watch these, even when things don't work right away. For someone who works in IT all day, watching these is a good reminder for the soul to keep calm when things don't work.

I grew up dreaming about owning a MSX computer especially the models Expert and Hot-Bit (for the Brazilian market). For my frustration that never happened. Watching your videos brings me an indescribable and priceless feeling. Today I have access to powerful computers but the feeling is no longer present. Watching your show is really like traveling back in time. I just love it. Thanks.

Anxious to see part 3 of this series. As a Tandy SE Region Computer Sales Manager in the 70s I am particularly interested to see this one working again! :-) Cheers. S

I love the Trash to Treasure series. I described them to a friend as following this format: Part 1: Here's a thing, here's some information about the thing. Is the thing stuffed? How stuffed is it? Part 2: Beyond how stuffed is it, in precisely which way is it stuffed? Let's find out! Part 3: Sometimes included in Part 2 for less-stuffed machines, let's fix how stuffed it is! Part 4 (or 3): Now we return it to its former glory, and make it look and work as new. Unlike doing a single long video, it really helps with jumping into specific parts for reference.

What a relaxing way to end the day. Thanks, Cave Man!

Nice neat soldering particularly on the keyboard ribbon cable. Enjoying this series even as a BBC model B man. The TRS80 certainly has its place in the pantheon of those things we used to call Microcomputers and I'm looking forward to the episode when you see what you can get done with such a machine.

Congratulations on getting it up and running. The sound of the TRS-80 keyboard is the sound of my childhood. It's very distinctive and made typing in those long long basic programs much easier!

Trash to treasure episode... the peak of the week :D

I just bought myself one of the new Hakko FR301-03 desoldering tools. Christened it by replacing the caps on an old ColecoVision and it was SO much easier than the solder sucker/braid that I used before (i.e. the same method you use in the video). I highly recommend this tool - it would have saved you an enormous amount of time desoldering those keyboard connector pins.

Hello. New to the cave. Really enjoyed the careful, deliberate, and methodical pace you go about with the troubleshooting and repair. Thank you for taking your time and explaining steps as you go along. Looking forward to the upcoming episodes and will start working on viewing your earlier episodes.

Great work and another great video, but yes that keyboard sounds fantastic. When coding and you're getting a clacky sound and good feedback (rather than a spongy mess of a keyboard) you feel like you're accomplishing something as you hit those keys!

Your 12v on the RAM chips (4116) was 9.5v. You need to check the 12v Regulator. And it's easier to cut sections out of rubber tubing for the spacers, than 3D printing them. If you are looking to repaint the case, the closest color is Mercedes Silver.

I call this a CoCo and consider a TRS-80 the larger system. I bought a Color Computer 2 in 1986 with my own money when I was 10. It was a nice machine and I did a good bit of basic programming on it.

I appreciate how mellow your channel is.

My TRS-80 had the graphics expansion board. It allowed me to define my own graphics with ease.

Trash-80! Love it! I'm actually getting back into trying to program for the video chipset. The Motorola 6847. It was very basic but it actually had some page flipping modes and a few colours. I'm surprised anybody did anything of note on it. So limited but still pretty good for the time!

Great episode neil.. now you got me waiting for episode 3. Excellent as always ..... Kim 😀

The music and shots in the intro for this video remind me of the beginning of a How It's Made episode.

I was so pleasesed I guest right about the RAM. Great videos

You're doing the Lord's work. Thank You!

Another enjoyable episode - I concur re: getting a vacuum pump desoldering tool, would've made short work of removing the ribbon cable with (virtually) no fear of lifting traces. The sound of that keyboard was a nostalgia trip for me, some of my first experiences using a computer were on a TRS-80 , at the age of 11 or 12 - and that sound is oddly familiar all these years later.

Onya 'Beardy Bkloke' from Australia. Love this stuff!

Here he is, The man with the little brush! Good job on that soldering, looked intricate.

Wonderful. Thank you for this, I look forward to seeing her in full restored glory!

Informative, inspirational and very relaxing to watch - fantastic

"I hope you'll join me for episode 3..." Well, yeah; that's a given. Your videos are very intriguing.

That solder wick looked pretty "dry", it might well benefit from a bit of liquid flux from a flux pen on it. Also - you might find it easier to de-solder if you apply some fresh leaded solder to the joint. This tends to make it flow better when you suck it out. If you can, once the solder is liquid, just move your iron to the edge of the pad to keep it molten, and try to place the sucker tube entirely over the pin / hole, this ensures the air is sucked through the hole, and not around the edge of the joint.

Nice video , well made and well narrated, waiting for part 3 now...

Making good progress with this project :)

I love the British Airways In Flight Music you provided! Very relaxing! 😀🙂🙂

nice one. the good old trash 80. love it

TIP: When soldering headers on to a board, solder the 2 opposite end pins first then work your way along. That way you can be sure the pins will not ride up as you solder to give that gap you warned about :)

Great episode. I look forward to the next one.

Two common problems with Model Is were the silver solder used for the edge connectors (they'd corrode quickly), and keybounce. IIRC the lowercase kit may have improved the keybounce but there was a setting in NEWDOS/80 for it I believe.

As always, great video. Thank you.

Where is EP 3? For the love of all things 8 bit please. hahaha. Can't wait to see it. Amazing series so far, like always so what am I saying. Keep it up man, love your works.

you are just pure class sir. excellent.

Enjoyed these type of vids. Thanks for uploading.

Another excellent video and more sterling work from one of the genuinely great channels on KZfaq!

Love the sounds of those keys! Listening to that sound, I half expect to see Bonnie pop around the corner and work on KITT

Love this video! I like how well you describe the debugging process! Also your game display in the background looks great. Nice job!

Another fun episode, very informative.

Often to remove old solder, you want to first apply new solder. It seems counter intuitive, but it has to do with heat transfer stuff, and the old solder tends to suck. It does work, I had to do that for fixing my TRS-80 last month

I am astonished that you haven't invested in a proper de-soldering tool for all the re-work you do, highly recommended. That said, even thought I have a great de-soldering tool, sometimes after removing pins and leads, rather than move to the rework bench, I just heat the solder pad and poke in a toothpick or cocktail stick in the hole to clear it. Keep the stick dead vertical to avoid breaking the tip off in the hole and it works quickly and reliably for hundreds of holes, and you can afford plenty of spares! :-) I hope this tip comes in handy.

Comin' together nicely, sir!

how can anyone give these videos a thumbs down, 7 people, really! behave

Love your videos - very insightful.

I must say that I am deeply impressed on your level of patience and craftsmanship in handling that manual solder sucker. Until now they have always seemed completely useless to me. Although I will probably still be using my desoldering iron in the future... simply to prevent any further hair loss.

Nice! I am in the process of sourcing modern components to replace all the components on a C64, mostly as good practice for my soldering but also to extend the life of it.

Love these videos. Makes me want to get my soldering iron out and work on my 7800 😀

Love these restoration videos keep them coming please 👍

A proper vacum desodering gun is a god send. One you are less likely to damage the board you are trying to extract components from. Two it makes the proccess a lot faster, three it can make desoldering a stubbon component a breeze. Four you can desolder multilayer boards. The hand pumps are only really any good for singal sisded boards. Sometimes you can get them to work on a dual layer board, but a multilayer board & you are in for a fustrating time. I got mine when restoring my IBM 5150 as the standard methods were damaging the mobo which are really rear & kind of pricy these days.

Great episode!!!

Alps switches are generally the best you can buy. If you haven't looked into it I highly recommend looking for something that uses Alps SKCM Blue switches. Or just get a clicky Matias board.

Alright!!! Been waiting for part 2 to be loaded up Neil. Hold on, I need the popcorn and soda pop to watch this. I already know it will be good. 8^) Anthony..

looking forward to the next part

God if I could get that same clack with my modern keyboard...

Soup nazi probably owned this TRS-80 He was constantly typing N-o soup 4 U N-o soup 4 U N-o soup 4 U

Those keys sound rather satisfying.

Fascinating video as always

You can start testing the cassette interface, many hundreds of TRS-80 software programs on cassette.

Luckily no creepy crawlies this time.

Awesome video as always

This was great. Thanks!

love the music you use, not only do I get to see old computers get fixed but I always get some amazing music to go with it...... so good and I am so happy you got the music all listed!

Great content, as per usual :) I'd love to see you restore a TI-99/4A some day, it's a really underappreciated micro.

Be careful rubbing wick across a board. Thats a sure fire way to rip off pads. Also adding some fresh solder before using the solder sucker can help a lot. Seems counter intuitive but it works.

Great Video! I love the trash to treasures! If you need anything 3d printing, I can print rigid and fixable materials as well as design parts, I don't mind donating to the crusade!

Thank you Neil. I personally believe you would do good making a couple of pounds making DVD's of your works regarding your Nerd Cave materials bro. I mean... the videos are finely detailed, reliable sourcing , a video commentator with a great personality, and a fella with a calm manner to make any amature feel like a pro after seeing your works. 8^) I wholeheartedly feel it would be a success bro . Think of the awesome possibilities. 8^) Anthony..

I don't know if it would work with that type of key, but on occasion when nothing else has worked I've drilled tiny holes in the switch's plastic housing to get the contact cleaning in, and it's worked like a charm! I've done this with great results on sealed potentiometers too. You've got to be careful obviously though because if you get any plastic shavings inside from drilling that of course will be an issue. If you're worried about leaving the hole open a drop of glue or piece of tape fixes that. If you're constantly working on electronics I can't highly recommend enough getting a professional desolder gun, they're not cheap at $200+ for a good one but they make life sooooo much easier, you can even strip boards bare to clean corrosion and such in extreme cases, I once did that with a rare arcade PCB that apparently some kid decided to treat as a painting canvas and after a bit of work you'd never know now.

Another great video - not sure if you ever saw my zx81 link on twitter, the auction has probably finished now, but would have loved to see you assemble one of those. Anyway, as always, really enjoying your videos - keep up the great work and I look forward to part 3 :)

Brilliant!, thank you.

Buckling spring keys are the best, for work I use a Unicomp (reproduction IBM Model m)

hell yeah, alps switches!

I love how people are circling back around to loving mechanical keyboard sounds after we spent decades trying to soften the godawful clatter they make.

Ah Microsoft midtown madness, the hours me and my buddies wasted on cops and robbers. Happy days! 😊

Your skills are amazing! If I had a third of your skills I'd be happy. I have a beeb that needs those skills

And now the u key is the best working key of the whole keyboard :-)

ok thx i will take a look

Good channel, great content. I like it 😀

The only game I've ever played on the TRS-80 was Dungeons of Daggorath. I don't remember how many hours I spent playing this game.

My first computer. I must dig it out of the loft one day

Hahahaha. Well I'm honored kind sir. 86) But personally, I think it would help expand you even more Neil. I mean you already have a whopping 49,000 subs and counting and seeing you have a great fan base, I think you would be certain you have sales for sure....Even from me kind sir. 8^) Anthony..

interesting how the ribbon cable design is similar to what was used in the game gear a decade later, they made the connections thinner but it still attached the same way (and is just as fragile and crappy)

I got loads of switches looks the same as the tatung Einstein ones

Don't you have a hot air station? That might have helped with the ribbon removal. Great work though! Can't wait for the next episode!

Love the analogue-synth sounding bits in the soundtrack on this.... it takes me right back to when we were all crazy for the future... future... future.

You need a better solder sucker my friend. A good solder sucker would have made that job much, much easier.

7:08 Is that Polish soldering paste I see? I have the same one, didn't know you could buy it in the UK.

Makes sense it uses alps SKCC switches. Too bad they don't make them anymore.

That round metal container you used to push the sicking pin of the connector looks suspiciously like a can from a Double 8 film reel.

Another wonderful video! I wonder if I could get a keyboard like that for my editing machine?
