Repairing a SEALED vintage Mac
HTML-код
- Опубликовано: 27 июн 2024
- Anyone who has had or worked on a Macintosh Classic knows that it's not IF it will fail, but WHEN and HOW BAD. Watch as I unbox this New Old Stock Compact Macintosh from 1990.
Will the analog board be too far gone? Has the battery exploded and eaten through half of the logic board? Find out if this mac is dead, or if it miraculously was spared from it's fate.
As a reminder, I provide a lot of detail throughout the video in the subtitles, so if you're interested, turn on Closed Captions - let me know who can find the @LGR reference ;)

I've never seen one of these so perfectly clean, not a speck of dust, un-yellowed plastic. Pretty.
Last time I saw one like that I was in middle school when that was new.
I totally respect your perseverance. I can’t wrap my head around how insanely complicated it must be to have the skills necessary to fix the computer.
I hope Apple reward you for your efforts here. Just beautiful to see this old classic piece of History get fixed and come to life
I do it because I love this stuff as I’m sure you feel the same about your collection as well… having said that, would be nice to get a shoutout from Apple ;).
Seriously though, this was a lot of fun and I’m glad you enjoyed it!
Would you consider selling it?@@polymatt
Apple only sees money signs
Considering Apple nowadays, it won’t happen unfortunately.
The Apple from back then is dead.
Now it’s “highest valued tech company in the world” Apple. Greedy Apple.
They will probably sue him
Stellar job - thank you for unboxing, repairing, recording, editing, posting, and preserving. Appreciate how much work you put in to this project!
I’m glad you enjoyed it. Thanks for the kind words!
I personally hate the mentality of people keeping old electronics in the box, while it's certainly a way to preserve the contents of the box... the main attraction itself is likely to have failed and is just rotting in its own packaging. Great job giving this thing the life it deserves.
Excellent work. It's great that this little piece of computer history found its way into the hands of someone who could restore it. That's gotta be the nicest mac classic specimen around.
You really did that Mac justice. Beautiful work. Now it will be enjoyed for many years to come.
Thank you! and that was the idea. I wanted to make sure it can stay in pristine shape and enjoyed for a long time.
stumbled across this by accident and was totally blown away!!! The unboxing was pure gold!!! and seeing that screen light up at the end made me grin from ear to ear!
That was amazing to watch the process! Love the info in the captions.
Glad you enjoyed it!
Holy crap, this video had me emotionally invested in that little Mac (it liiiiiiives). This was hugely interesting and informative, but also just had a really nice story to it. I can't wait to see what else you put up. This was wonderful!
Haha thanks so much!
A pleasure to watch such a skilfully executed repair, attention to detail gets a 10/10. Good to see such care taken with that golden oldie 👍
I bought one of these new, and I remember the unboxing experience as being magical, watching your video I had a sense of the unique smell of a 90s Mac coming out of the box! The manual for these was top quality, as was everything including the packing materials. It was my first Mac. Yesterday I opened a MacBook Air 15” and I feel the unboxing experience today is still quite an experience.
I feel like smell is one of the strongest emotional triggers - and this smelled exactly like you would expect! It was awesome. I think Apple still does a great job with the unboxing experience, but to your point nothing beats the old school manuals that were so comprehensive they taught you how to use a mouse!
Fantastic video, thanks for the closeups. This is a joy to watch.
Real treat to find a video like this
The best thing I've seen on RUclips lately.
Thank you!
Thanks so much!!
This is amazing, very satisfying to watch! I wish you the best!
it's crazy how this wasn't permanently damaged! i wasn't around when old tech like this existed but it's always interesting to see how it was done back in the day before so many of the standards today got established with the modern PC
Great work, glad you went into this knowing exactly what to expect and what to do to get it back on its feet again. Your videography is very nice too.
Beautiful! Good job man.
Awesome video production and what a journey, great work man.
Thanks so much. Glad you enjoyed it!
Great job, you did this little machine a good turn with care and precision. Great to see it's in good hands. Incredible to see it in original condition like this.
Brilliant job! I worked for Apple when these were brand new and it's great to see one in such good cosmetic shape be brought back from the dead.
An insanely good find! Good job with the restoration.
Thanks so much - yeah it was a totally chance find. It was even local!
Outstanding. I remember when they were released (in Australia, 1991?), I schlepped over to ComputerLand to drool over it for a while, then went home to my Z80 computer.
Same. These were unobtainium for me when they first came out. What was your z80? Only one I had was a Commodore 128.
Amazing! Loved the unboxing, really felt like I was there. And incredible troubleshooting and tenacity to keep going. Loved it.
Thanks! This one turned out to be a bit of a rollercoaster 😁
I feel like I've come across a multi-million subscriber channel before it got big. Fantastic video and what a computer! Wonder how many of perfectly(-ish) preserved computers like this are still sitting in someone's attic or garage just waiting to be found.
I'm glad this was in the right hands. Thank you for the great video.
Glad you enjoyed it!
very cool find Matt!
awesome quality video editing.
I will subscribe!
Glad you enjoyed it and thanks so much for the sub!
Start to finish I was ENTHRALLED. Thanks so much for capturing and sharing this!
Nice! Glad you enjoyed it.
Excellent video! I enjoyed waiting it! I like the format, it’s fresh and athletic. Keep on, please! Looking forward for to next videos
Thanks and will do!
Fantastic job!
Great video of an alltime Classic Apple Computer. Had this one myself. Nice job getting it back to life.
Amazing job! What an amazing work!
Thanks so much! Glad you enjoyed it.
This was such a lovely, relaxing, beautifully-made video. Thank you for sharing this, and congrats on your incredible new Classic!
Thank you so much!
Another excellent video!
Glad you enjoyed it!
Accidentally found your video. Very informative and interesting. You are awesome❤
Fantastic. Thank you. I'm in the process of restoring an old used mac classic. Very envious of your find.
Restoration can be such fun and fulfilling projects. Best of luck on your compact Mac!
AWESON! I also have an old Mac at my home, but I used to mistakenly believe that it would start up anytime I turned it on. I have now learned that it requires tremendous effort to make it work. Your video has been a great learning experience for me!
Glad it helped! Before I started getting back into these computers a few years back, I totally thought they would just turn on. Its been a really cool experiencing learning about them on a hardware level and seeing what time does to some components.
That takes me back. I used to do DTP on these things in 1991. Crazy to think how we managed with that tiny little screen.
Wow! I'll echo what other commenters have said: video is enthralling and masterfully produced. Yea... your channel is going to take off with this type of content! And... what a find!! Thanks for sharing the process.. a true showcase of next-level diagnostic and troubleshooting skills, repair skills, and all captured with top-notch production quality!
Thanks so much Chris! Really appreciate the support!
100% agree and thanks for pointing this out, @RetroTechChris as I might have missed it. The retro community is stelar.
this was incredible to watch. thank you!
Glad you enjoyed it!
Wow glad to know 4:17 the Apple keyboard was assembled in Malaysia 🇲🇾 ❤
Super cool. That is one nice restoration and thanks for sharing it! Keep up the good work.
Thank you very much!
Another sign I am old…these were the computers I used in college on 90s…pretty cool 😎
Wow-the condition of that classic makes it look like you went through a time-warp and brought it back! Looks AMAZING! Great job restoring it! Thanks for another great video.
Thanks so much! That was the first time I’ve unboxed a compact Mac. Even when I was a kid and had one we bought it used from our school. This was such a cool experience and glad I was able to get it working! Thanks again for watching and glad you enjoyed!
This was amazing to watch. I love watching unboxing vids of NOS retro computers and video game systems etc. I have a new in the box sealed ColecoVision that I am contemplating opening but love just admiring it on my shelf for now. I had one as a kid so its so nostalgic for me.
Thank you for the synthwave soundtrack! Gave me all the feels!
Glad you enjoyed it!
Wow what an absolute work of art. It’s like opening a time capsule. Thanks for sharing!
Glad you enjoyed it!
First video ive seen of yours, but quite impressed! Well done sir
Hey thanks so much! Glad you enjoyed it and got a lot of fun projects coming up :)
Wow I am impressed and it was so entertaining to watch it being restored into Mac Classic from start to finish. And the length was not long or shot. Beautifully edited.
Thanks so much!
Wow! Been working on macs for 35 years now. This takes me back. Thanks for posting this 🙂
Glad you enjoyed it!
Best unboxing video for this mac and you did such and awesome repair job!
Thank you! It was a fun one.
great video, you did a fantastic job with this Apple Classic.
Glad you liked it!
I'm so glad I randomly stumbled upon this video...simply amazing video thank you so much for going into detail and showing your skills. When the chime came in and the monitor turned on I was like YASSS! lol!
Really glad you enjoyed it! I know I was super happy when that thing finally chimed and I saw the screen slowly come to life!
Fascinating. Thank you.
You are amazing !!!!! Back to 90!!!!
Thank you for buying this and showing us
Thanks for watching! Was a really fun project.
I am speechless and proud to see your work. Growing up around the Mac is one of those life-long tools I enjoyed making a living with.
Thanks so much! Glad you enjoyed the video. It was such a fun project for me to work on. This was one of the first computers I owned that was “my” computer growing up.
Geez, I'm pc user and builder, but I was just captivated by this video (my first personal computer, though, was a Mac Plus, bought it in 1986, had it for four years and it worked great). Wow, nice job. Thanks for posting this. You do geek proud.
Glad you enjoyed it!
Man, seeing a pristine mac classic really brings me back. That perfect color, no discolorations, no aging on any of the metal. When I was a young kid, I was too poor to get a computer. Game consoles were about the extent our finances would allow, but my friend got a brand new mac classic just for his bedroom (lucky punk). I remember being so excited with him when his dad walked in the door with it and brought it to his room, unboxed it, and put it on his desk. ...Fortunately our power on moment was a flip of the switch, contrasting with yours. ;)
Man, this was amazing! Judging by the quality of the video I easily thought you were an established RUclipsr with a million subscribers. A tiny advice: the subtitles were sometimes a bit too quick to read, you might leave them on for a few more seconds in your future videos. At any rate, I see great future ahead of you, keep up the good work!
Thanks so much and great advice. Luckily subtitles are something I can go back and edit at any time. I agree some are too quick so I’ll go back and see if I can pace them out a bit more. Thanks again for the kind words and glad you like the content!
Literally just had the same realization right before I looked at this comment.
The subtitles should be replaced by voiceover.
@@polymattwhat do you use to get subtitles on you videos I don’t want to manually put them in
@@mojoblues66he put subtitles for ppl who are deaf hard of hearing that’s why RUclipsrs just like my channel put subtitles but I can’t find a program to do it automatically
The process of opening up the box of a new computer for the first time when computers were something rather special in the home (not rare, but far from ubiquitous, unlike today), the excitement at seeing the new model up close and personal and giddily knowing that it's YOURS; I miss that. That Mac looks imacculate inside, the PCBs and chips looking brand spanking new. That cruelly created the illusion that it was going to fire up first time! Great work getting it back up and running.
So awesome to see that original gray instead of the oxidized yellow color unsealed ones become.
And to see that boot screen after all your effort, a thing of such beauty and boot speed.
why am I so happy to see this thing brought back to life
it's like watching ER doctor do a series of procedure to save a dying patient
AMAZING WORK!
Thank you! Glad you enjoyed it.
Didn’t realize you were the thinkpad 701c guy until after I finished this! Bravo to your work preserving those amazing laptops, and this Classic too! You’ve got great skills and I hope you keep making videos. Would love to have voiceovers too if you’re up to it.
Thanks so much - yeah, I've definitely done a deep dive on the 701c line but I liked the idea of using this format to show some of the other things I do as well. Glad you enjoyed it!
This video lession me that "Never Give up" your hardwork. Excellent. 👍
Thanks so much! Glad you enjoyed it.
Your most welcome@@polymatt
Congratulations 🎉 Excellent job
Thanks so much!
Very nicely presented, and very clear. I like your explanation of everything that you did along the way.
Much appreciated. I think the subtitles give me a lot of flexibility in how I "talk" about the process. I'm glad you find it useful.
So good. Thank you!
Thanks for making this video. Have some mac. My old 1980s Amiga still work. Seeing a NEW old computer coming out of the box.... so perfectly new. Miss that old light-grey color.
I commend you for the use of chip quick for the removal of the SMT caps. It really minimizes the possibility of damaging the PCB.😊
Gosh this was a joy to watch.
I have a G3 project on the horizon needed the analog board recapped. I’m experienced with soldering so it doesn’t worry me, but this video definitely reignited the itch to get in and do it
Thank you so much! They’re such fun projects. Getting them working again is the best feeling.
OMG love it. Never been used for so long.
Great vid! I have a Classic II that one day I'll have to recap as well when i get comfortable enough to do it. Speaker's starting to distort and the display had lines during boot randomly. Fun times await
Brings me back to Christmas Eve.
Holy... this video is so impressive!
Hey thanks so much! Glad you enjoyed it.
I had forgotten what a sweet little computer the Classic was! After the Mac Plus I went straight to Mac II's with 24bit colour. I have a company, 'David Myers and Associates' based in Australia and I was commissioned to design and produce Apple's very first digital 'Direct To Screen' presentation introducing 'Mac OS-7' and all of it's features. I designed the presentations on a Mac II with 20Mb SCSI 'Syquest' external drives and Apple ran the shows on other Mac II's connected to modified Sony RGB theater projectors, worldwide. You have inspired me to search for a similar unit as beautiful as yours. Thanks for bringing back all those memories! Cheers, David.
Thanks David! Glad I was able to re-spark you interest. Getting to experience something like unboxing one of these is pretty unreal.
Fantastic video! I miss my old mac classic
amazing , last time i seen one this clean . must be like 30 years ago.
this is so relaxing :)
"Aaaah FRESH PORTS!" OMG I read that with Clint's voice in my head 😆
Haha right? That’s the first thing I thought of when I looked at the back.
What an awesome video. From Macintrash to Macintosh! Now you can go play Zork! But seriously, I throughly enjoyed that. After getting blamed for breaking one of those as a kid (wasn’t my fault) it’s amazing what modern parts can do to old machines.
Amazing ❤️ seeing that brand new, crisp monochrome CRT come to life 👍
This was a great video, my first experience with a Mac was a Macintosh Plus, it had a battery backup, etc. We used it in Tanzania, East Africa in the early 90s and it was a workhorse. I was a kid and mostly used it for games, but my dad did publishing with it for the local print shop we were supporting as part of Eastern Mennonite Missions. I will never forget that little beast, even after the battery backup was killed in a power surge, we still used it and it was a sad day when we left it behind when we came back to the states. I will always remember playing Scarab of Ra, and the various kids games I had on it, and looking at the newsletters we did up on it, it has that authentic 90s mac look that was unique. Truly a magnificent piece of technology! It brought tears to me eyes seeing that untouched piece of history you restored.
What an amazing story. Thank you so much for sharing! Amazing how these old machines can bring back so many memories.
@@polymatt Yea, I really appreciate you sharing your restoration video, and taking the time, effort and expense to restore that thing. I'm amazed that some of these old computers are being found untouched to this day. Seeing a mac or an IBM with a massive spiral bound notebook as a manual, and being lovingly individually packaged really is a dissonance between then and now. We had the most powerful desktop computer in the village, our competition was one of those portable LCD style IBMs or something that the Canadian missionaries up the road had. Having a PC in the 90s in Tanzania was no small matter, the print shop my day was upgrading and eventually took over management of, actually was typesetting with print tech from the 40s or something, and the stuff we did with our tech we brought and new print shop stuff let the village church go from typesetting basic hymnals by hand to us printing calendars, full books, new literature and so much more. It was eye-opening just how far we pushed that village into the modern era. People don't appreciate just how portable those little macs were back in the 90s, and just where around the world they ended up and the massive impact that they had all over the globe. They were very versatile and came in so many varieties.
I loved your content, edit etc. keep it
Glad you enjoy it!
This still whips the speed
of my 2017 iMac at startup.
Right? Theres also a ROM you could get that would make this thing book in a couple seconds. One good thing about old machines.
Man I’m glad you found one brand new and you were able to fix it and get it working. I remember playing the Oregon Trail on one of them machines. Man brought back some memories. Good job on getting this piece of history running again. 👍
Yes! For me it was Carmen Sandiego and HyperCard. Glad you enjoyed it!
Loved the video and definitely shared the excitement in the unboxing. The black gloves were a little overkill but that's just me me.
Very nice video. Just goes to further show that no aluminum electrolytic capacitor has eternal life, not even on a sealed and never-used machine. I must say I did grimace when I saw that paper speaker get dunked in IPA, but it certainly was a relief to see it works fine after drying. Also very interesting to see just how many components need replacing, above and beyond just the capacitors. Your video does a long way to warn people who buy sealed computers that they still probably need repair work, and such would need to be factored into the cost of the machine. No doubt you paid a pretty penny for that sealed Classic. But it certainly is lovely to behold, and now that it's working, I know it means something very special to you. It would to me. Thanks for sharing!
complimenti un grandissimo lavoro!!
Thank you very much!
When I was attending Uni in the early 90's I remember there was a student in my maths class always carry his Macintosh Classic into the lecture theatre just like what they do with laptops nowadays. Thanks for the fond memories.
Thats amazing - my first exposure to these was in grade school. We had an entire lab of Apple II systems and one day we got a couple compact macs. Everyone fought over getting a seat at one. I love the nostalgia something like this brings back for people. Glad you enjoyed watching!
Brings back my memories of when I opened my Mac Classic. I loved playing Apache Strike on it.
Great game!
very impressing!!!
Awesome video!
Thanks Sean!
Thats almost a repair guide! Great vid
Haha much appreciated! I had no idea what to expect so I’m super happy I was able to bring it back to life :)
It's so CLEAN. I have always thought the Classic was such a pleasing and complete design.
Same, I always loved the super compact design. My first time dialing up to a BBS was on one of these and whenever I see one, I associate it with the "soothing" sounds of dialup. Was a magical experience back in the day.
Taking it apart and checking before powering on was an EXTREMELY good decidion.
I have watched a lot of repairs videos, and to see something from 33 years ago only started to work after being left on the shelf is amazing. I can only dream of fixing some of the things I have put aside due to electrical/electronic breakdown, maybe one day
Literally had Clint's voice in my head when you got to the money shot of those port's 🤣
Haha - totally. Not sure if you saw the subtitles, but I will never NOT be able to think of unboxing a new computer without that voice in my head.
