Regarding open drives and clean rooms. Back in the early 80s I was a repair tech for a computer manufacturer. I helped train new techs. We had a 10 meg hard drive from which we removed the cover to show new techs how these drives worked. This was a time when one could still smoke at their desks. We used to flick cigarette ashes onto the spinning platters of the disk and watch the heads fling the ashes off the platters. That disk ran for the entire 2 years I worked at the factory and never once had a failure. Those were the fun days of computer repair.
I've actually found that the main obstacle to opening and then resealing a hard disk is the torque of the fasteners. Always try to establish what the torque is before opening. If you torque the screws back to what they were, it almost always works.
I doubt if that would work these days. The information density on the disk was a whole lot less then than it is now. (10 MB over a whole disk vs 10TB today). Basically a bit occupies like a few atoms now, so very easy to obscure with particles of crap.
That's because, in general, there is no reason to ever fix one because replacements are available. This fix is not going to last. He needs to use wires.
I have many times. Just use magnet wire to jump past the damage. Removing the plastic coating can be an issue with some flat flex cables, but it's not impossible. A razor blade is good enough for most, but if really delicate, steel wool is a better option.
PenMac. They built so few of these. Amazing that you got your hands on one. This project shutting down is what eventually led to Graphing Calculator, which has it's own amazing story.
I'm one of your Patrons and I watch almost every video. The cadence of your tone and camera work is great. Thanks for showing all the hardware from the past, I find them relaxing and informative.
This is the clearest, most concise old computer repair channel on UA-cam. It would have been easy to drag this out, but it’s just not his style. Respect.
I'm not even joking when I said I had a HDD in a 286 Samsung laptop that had the gasket fail and get sticky goo over the top platter. Deciding the drive was toast and I had nothing to loose I washed it...with water and soap...then blew dry it with compressed air. Put it back together and it literally booted up. Scandisk did show a few bad sectors but the drive worked enough to explore.
Hey, you don't need a whole clean room to do hard drive repair safely, a laminar flow hood will do just fine. Especially for older drives, you can cheaply DIY one with a Corsi-Rosenthal box.
Great video - never seen anything like that before. Somehow I miss the sounds of hard drives but then I realise the speed and storage limitations from back then, and I'm happy we have SSDs now!
Harddrives die if dropped (else can last many decades). But SSD die already when left unpowered for few years (the more writes, the faster) because they are DRAM with 1 year refresh rate. So with any nowadays tablet or laptop it is unlikely to recover any of its data when found on an attic only 10 years later.
Amazing work. Clear that you are a professional. Seeing the mess when you opened it up would probably scare off 80-90% of people immediately. A delicate procedure putting humpty dumpty back together again for sure.
An old trick with stuck drives is, to put them in the freezer over night. The cold sort of deactivates the sticky mess and if heads stuck the thermal contraction loosens them up.
I would think a big danger here is that when you take it out of the freezer, it could get moisture condensation on any of the circuitry that’s not inside the sealed drive part.
I do electronic repairs as a hobby on my channel, so I can’t tell you how many times projects like this go wrong, how time and labour intensive and nerve wracking they can be. Sourcing parts (especially for a freaking prototype tablet!!!), troubleshooting, brainstorming ideas… Very impressive, and the video itself is awesome! Respect! ❤
Ad Hoc is a term derived from Latin that means "For This" or "For This Situation." In the context of technology and computing, "Ad Hoc" refers to solutions that are developed specifically for a particular problem or task, without considering broader applications.
Seeing a working prototype of anything is an interesting thing to see. it shows where they are in the development stage and gives a few hints on what they were trying to accomplish. I can't help but think that this prototype is most likely an ancestor to the modern day iPad.
This reminds me a lot of the Modbook. For those who don't recall, a little over a decade ago, a company called Axiotron offered a kit (or service) to convert stock Core2Duo MacBooks into reversed touchscreen models just like this. They were fairly popular for a time.
I worked at RCA in the 80s at the lab that developed color TV among other things. They had an actual museum on site, it was very cool. Even the ceiling light panels were shaped like old TV screens. But it wasn’t usually open to the public.
Great work! I had a drive from an Amiga fail in the way you described, throwing sticky goop all over the platter and drive internals. It spun up, but there was no saving it as a working drive, never got a good read from it after that. What an amazing opportunity to work on such a machine!
In my opinion, this was a beautifully done video. Excellent story telling combined with excellent detective work. I very much look forward to the next installment.
Thanks for having us along on your adventure. This must have taken months to plan, acquire the hardware, execute, shoot, write, and edit. I'm amazed at your level of detail and storytelling ability, and the subject matter is just enthralling. I'm glad this prototype found its way to you and I can't wait for the next video!
That was great! I’d forgotten about those awesome old Powebooks! I had owned several of them including a Duo. I was so proud of that thing. Those were great days!!
One wow after another in this go-round, great show as always, Colin! Such an incredible find and ninja-level repair mastery, such a pleasure to watch you work!
I love this deep dive. Thank you for all the work you do. This is one of the best vintage channels on UA-cam and I get excited every time a new episode comes out. 🙏
Code name Snoopy / Blue Jewel, if I remember correctly. Saw one of those in 1993. It was a great idea for the time: use it as a tablet when not docked, slide it into a Powerbook Duo Dock and bam! a full desktop computer.
*Bows down to your classic PowerBook logic board and spinner hard drive knowledge* Absolutely loved this! I was on the edge of my seat watching the flex cable repair, but figured if you had attempted it, you knew what you were doing. :)
AYO NO WAY. YOU HAVE ONE OF THEESE?! Edit: (NAH, SCREW THAT, HE HAS MORE THAN ONE!!!!) I thought theese were all just.. concepts!! I never knew they actually existed! Dude you matermind! How did you get this?!
I wonder if this was ever shown at any conventions such as WWDC or CES. Maybe only shown to people who had signed non-disclosure agreements, if so might explain why nothing written about it or any old video? It would be cool if there was a video like from Computer Chronicles from the time.
Been watching you for years. I love every video and topic. This though, this was my favorite to date! I would have never seen this had you not done this work and jumped head first. Thanks for sharing with us all!
A spinning hard drive in a handheld device sounds crazy, especially with hard drive of this size! I've known that some ipods have miniature hard drives instead of anything solid-state, but this thing just looks like a beheaded laptop.
I carried an iPod Video with a 60GB HDD in my pocket for a few years, playing music while I walked around and whatnot. The drive in this video is about twice the size of that one.
I still have a classic 160 with its 2.5" hdd; I thought about putting a flash drive in it once, but the noise it makes is part of the haptic experience of using it.
Harddrives die if dropped (else can last many decades). But SSD die already when left unpowered for few years (the more writes, the faster) because they are DRAM with 1 year refresh rate. So with any nowadays tablet or laptop it is unlikely to recover any of its data when found on an attic only 10 years later.
I have a Powerbook Duo 2300c of which I was recently able to get the original hard drive backed up for personal archival. It once belonged to a long time Motorola employee.
i find it reassuring that even a company like apple has prototypes that are as hacked together as my own... and kudos to you for this video - some serious electronics and embedded system development skills here.
This is a fascinating look into what, eventually, became the iPad we all know and mostly (JUST PUT MacOS ON IT ALREADY) love. Makes you wonder why Apple won't release the source code to things like Copland, there are so many Apple enthusiasts out there who'd love to explore the "what could've been"s.
Instead of opening the drive, you could twist the drive. It won't feel like it has moved at all, but that small amount of flex could release the actuator.
It's nice to see a flat flex cable repair be *successful* for once, seems that more often than not they go awry. Awesome episode, can't wait for next week's! And congrats on 400K 🥳
This is a really well made video. Thanks for it. You could do a short on taking apart the HDD and blur the disks out cause that part was pretty interesting. So much work and problem solving done. I look forward to the next one.
Back in 1993 as a 15yo I attended an Apple info night at AppleCentre Darwin, launching the Mac Quadra 840av, the AV displays, and the original Newton. Certainly looks to me like this had to have come from those days of Newton development... Yes?? And don't think I missed the icon for "Casper"! Casper was Apple's early name for its voice recognition software - You used to be able to ask the early AV Macs "Who is Casper?" and ahhhh yeah, they said something that is gone from my memory right now.
When repairing foil cables (with copper traces), always solder a thin copper wire (single wire out of a wick cable) across the gap. It will be 10 times stronger than only solder (which tends to fall off after a year). Dismantling a harddrive without cleanroom is very risky. Any dust particle will cause a chain reaction of debris that kills the drive within hours to a month (but at least it lasted long enough to backup a binary copy). To free a stuck head arm, I read that it can help to rotate the drive itself causing a rotary impact to shake it loose. Also warming by hairdryer may help to soften sticky stuff, and cold (put into fridge) can help to break it loos either (like chewing gum stains in hair).
Never connect power to a Duo before a recap. They leak so bad (particularly the 270c) connection to power destroys the circuit. Additionally only use newer power adaptors like from the powerbook or iBook G3 (clamshell) as there is a large RIFA in those original power supplies that will go up like a Christmas tree
I hope you at least put some oil on the shield after removing the rust. It will rapidly rust again if you didn't. A proper solution would be to tin the shield so rust can't reform at all.
I'm very glad you used DD to create a copy! It makes a copy of every single byte on the disk so it is the perfect way to actually backup a hard drive. If a drive has hard bad sectors, ddrescue can create a copy despite I/O errors by skipping the bad sectors first instead of retrying and only trying to read them again after having the rest ofthe data copied. I was scared that you are letting the OS mount the hard drive without forcing it to mount new drives under read only mode because the OS might do some writes automatically when mounting a disk in read write.
Dude, dude...impressive work, simply amazing. I'm stunned. Thanks for sharing, the vids not over yet and I can't wait to see the end result but that flew cable fix was just insane. GAH a cliff hanger?!
I think it may have been displayed at Walt Disney world In the epcot future house they had a digital kitchen demo in 1996 along with an hd tv demo I believe they said it was for groceries and recapies
Dude this channel is great! the cinematography is crispy as hell and the quality of knowledge and content is of a high calibre, really good stuff dude!
I remember seeing the concept designs from the 80's and one of them being a touch screen device, I'm not surprised apple actually tried to make one, but I am surprised it made it into the wild. Awesome to see another rare bit of history spinning up and doing its thing again.
I remember in a 1980th German "Happy Computer" magazine was an Apple "Tablet" shown, which was supposed to have a vertically foldable screen (like a book) and optical storage card. But the thing was purely a non-working showcase prop without any real components.
man these old prototypes go for insane money i recall seeing a prototype walkman on ebay before, it was a wm-20r (wm-10r mk2 basically), listed for 10k and sure enough about a week later it was gone what i wouldnt give to have seen inside that thing lol
So what is this? Some sort of Powerbook Duo that's a tablet? The date codes do line up to other experiments at the time from Dauphin and Samsung. The 16mhz 68030 is also a dead giveaway considering that aforementioned examples used similar speced 386's.
I miss when Apple used to design brand new hardware and not just play it safe, like they’re doing now! So glad at least you got the prototype to turn on!
@Markimark151 yes but a heavily modified and incompatible with standard arm64 processors that ***apple*** designed. i'm not even an apple fan and even i know their silicon isn't off the shelf anymore
@@Markimark151 It is much better than at that time, since at that time it used a Motorola processor, something not of its own design. Now they design everything.
those bendy pcb cables crop up a lot in portable video gear from around that time, & I had to mend loads in sony vx-1000 dv camcorders. nice work. >looks at ipad< we've come a long way.
one of the small flotilla of ipad minis that my kids use- I've repaired it six times. each time I pry the shattered glass off another busted digitiser, I write the date on the shielding plate underneath. 😂

Great, now your test HDD is addicted to Nicotine. ;-D
BOOT FAILURE
Insert a stogie to continue
For a school project, I open and REPLACED the top cover with acrylics panel.
The HDD worked fo all demo I did.
It was a 6.4Gb IDE drive.
I am 27 years old, this is the coolest thing I have ever heard. I always used to open up my failing hdd's for fun when I was like 12 :p
I doubt if that would work these days. The information density on the disk was a whole lot less then than it is now. (10 MB over a whole disk vs 10TB today). Basically a bit occupies like a few atoms now, so very easy to obscure with particles of crap.
I've never seen anyone repair a flat flex cable before, this channel continues to be one of the very best on UA-cam.
That's because, in general, there is no reason to ever fix one because replacements are available.
This fix is not going to last. He needs to use wires.
I've done it. People say it is impossible but it isn't if you can isolate the wires inside. Giant pain though
It is a common practice for Apple emate because the ribbon cable is prone to damage. I think Colin has talked about this in his emate video.
I have many times. Just use magnet wire to jump past the damage. Removing the plastic coating can be an issue with some flat flex cables, but it's not impossible. A razor blade is good enough for most, but if really delicate, steel wool is a better option.
@@rich1051414 Yeah and this repair will never hold up. He needed to do it with wire.

Welcome to the channel
Welcome. Consistently great stuff here.
If you're interested in Apple while Jobs was gone, you're in for a ride.
Welcome, he’s got a great backlog of videos like this
AYOOOOO!!!! Been watching him for years dude, nice to see you in here!

The sound of that Connor hard drive brought back some memories. I had the same drive in my MacSE.
Ooh, cliffhanger ending! Looking forward to learning more in a future video.
When repairing a flex you should put a wire across, as a solder-only joint is extremely weak and will snap easily
For anyone wondering what this is, it is an early Apple PenLite prototype.
Hey, you don't need a whole clean room to do hard drive repair safely, a laminar flow hood will do just fine. Especially for older drives, you can cheaply DIY one with a Corsi-Rosenthal box.
Yet his repair worked fine
@@danielktdoranie Yes, thankfully! One can make sure the repairs stay working fine by whipping up a quick laminar flow station for cheap!
I don't have any Corgi-Rosincore boxes. Will an Amazon one do?
@@nickwallette6201 Sure, you can substitute the corgi with any terrier breed of similar size, and pine oil can be used in place of rosin.
@@bigmclargehuge1170 Haha :-D Thanks for playing. 👍
I consider myself quite an Apple geek and am rarely surprised by stuff but WOW, I'd never seen anything like this! Keep up the amazing work!!
there were a couple of times when i thought "holy shit he's actually going to do that". Respect for doing everything possible to fix it.
I really love how you are very delicate and procedural with repairs for vintage electronics and not just doing whatever might work! Awesome work!
Great video - never seen anything like that before. Somehow I miss the sounds of hard drives but then I realise the speed and storage limitations from back then, and I'm happy we have SSDs now!

Oooh! I worked on software for that. We were trying to build an iPad out of 1992 technology. Good times!

I wonder why Apple doesn't have a gallery museum of all their products.
i repair vintage macs professionally, internally they do in some departments.
They did and Jobs threw it out when he returned. He believed in the future and not the past.

I don't think I've ever been so invested in old hardware! Thank you so much for putting this all together
Colin really demonstrated his knowledge with this one. Great video.

That is simply amazing. I've repaired flat flex cable before, but I had never heard of the trick with the hard drive. Something to add to my toolbox!
Thanks for the ride down memory lane when I worked for Apple in Australia. I do remember this prototype being talked about too.
That was great! I’d forgotten about those awesome old Powebooks! I had owned several of them including a Duo. I was so proud of that thing. Those were great days!!

I would recommend ddrescue instead of dd if you are not sure about the condition of the drive.
AYO NO WAY.

Edit: (NAH, SCREW THAT, HE HAS MORE THAN ONE!!!!)

This is one of the most interesting videos about prototypes I've seen, you made an incredible work fixing it and archive all that you can, so great!
Excellent use of ancient product knowledge to glean design clues to restore functionality.
I recall seeing this tablet which is called PenLite on a website that had a bunch of Apple prototypes.
Around the same time Atari was working on the 'ST Pad'. Same external developer maybe?

what i wouldnt give to have seen inside that thing lol
Dude. You are good at this stuff, it's honestly impressive.
“If you like the video, I’d appreciate a thumbs up.”
Oh, you got the thumbs up BEFORE I watched the video. Your content is awesome.
Dang, leaving us on a cliffhanger! I can't wait! I loved the hard drive segment. Joining patreon because of this one.
Such an interesting dive into all that could’ve been from Apple in the 90s. Another great video from an awesome channel!
This is a masterwork.
So what is this? Some sort of Powerbook Duo that's a tablet? The date codes do line up to other experiments at the time from Dauphin and Samsung. The 16mhz 68030 is also a dead giveaway considering that aforementioned examples used similar speced 386's.
possibly a Penlite prototype
I miss when Apple used to design brand new hardware and not just play it safe, like they’re doing now! So glad at least you got the prototype to turn on!
The Apple M series is the most customization you have ever done, because everything is made by Apple and cooked of course by TMSC.
@@gatitosmiaomaio Apple themselves aren’t manufacturing the chip, they’re just using an ARM based processor for their Macs!
@Markimark151 yes but a heavily modified and incompatible with standard arm64 processors that ***apple*** designed. i'm not even an apple fan and even i know their silicon isn't off the shelf anymore
@@SoulcatcherLucario it’s Apple designed system on a chip, to work with their walled garden system, but it’s not their own architecture.
@@Markimark151 It is much better than at that time, since at that time it used a Motorola processor, something not of its own design. Now they design everything.
Loved seeing the work done on this cool machine!
Some sort of adventure dealing with HW being 3 decades old. Inspiring and entertaining!
Great save on this one! Such a cool piece of Apple's history, and now I CAN'T WAIT for the next instalment! :)
That was very interesting and your skills are impressive!😮
Personally I would have soldered some thin gauge wire to fix the flex. Just solder is too delicate.
those bendy pcb cables crop up a lot in portable video gear from around that time, & I had to mend loads in sony vx-1000 dv camcorders. nice work. >looks at ipad< we've come a long way.
one of the small flotilla of ipad minis that my kids use- I've repaired it six times. each time I pry the shattered glass off another busted digitiser, I write the date on the shielding plate underneath. 😂
