Thank you Adrian! I was not expecting a broken joint indeed - so weird that it caused all the frequencies to be 1/5 of the expected ones! Thanks for watching and for leaving a comment, really appreciated!
I know it must be demotivating getting declining views but I can confirm this is some of the best retro content on RU-vid! Thank you for all you do for the community and please keep up the amazing work
It is, I am not expecting my numbers to skyrocket but seeing each video doing worse than the previous one is indeed a bit sad. But thank you for your comment and for watching! It means a lot to me!
The RU-vid algorithm can be your friend or your worst enemy - most of the time it's both! But never give up! Your community enjoys the content you create! I learn a lot from your videos and hope that I will be able to apply what I learn soon (you know, that dreaded 486 motherboard)... Great job troubleshooting and finding the fault on this motherboard!
I've never seen the "giant ball of solder" removal technique you demonstrated at 12:46 . Pretty cool! It's always so satisfying to see a successful repair on nostalgic hardware like this. Thanks Tony!
This is the kind of content I like watching, the skill and patience to do these repairs is amazing. I've got a stack of boards set aside for the day that I have time to improve my repair skills.
I'm sad to hear your views are declining. You are easily one of my favorite channels to watch. To the point I wish you were releasing a lot more videos. Easily some of the best repair videos on RU-vid.
Great troubleshooting - love that it was just a simple loose pin! When you think it's going to be complicated, it seems like it's just simple sometimes... if you're lucky 😀
@@tony359 i'm the same way - learn by doing and trying 😀 it's so funny that it was masked when you pressed on the pin with the oscilloscope probe too making it even sneakier!
Would like to see more of these type of repairs on retro main boards. Keep up the good work 👍🏻 I actually have a socket 7 motherboard that needs fixing. Could send to you. Would love to see what’s wrong with it and if you fix it you can have it
This reminds me of what happened with one of Necroware's 386 mobos, where a defective capacitor caused the clock speed of the CPU to go rock bottom and the RTC also failed because of it IIRC.
Lets kick the algorithm a bit….I love the vintage hardware, remembers me in my earlier days where we built these and jumpered and clocked them the hard way 😊
Thank you, appreciated! Yes, every time I swap a CPU on a socket 7 and I have to go through the many jumpers, it reminds me how easy it is these days :)
I bought this board new back in the early 2000's, and used it for years. I found it and decided to see if it still works. Your videos were helpful in setting up the jumpers. thanks!
I rarely leave any comment or push the like button - but your videos are great and should be seen by more people. Looking at 8-bit-guy or similar channels, you should be up there as well. Appreciate your in depth knowledge, positive nature and that thinks can be fixed rather than thrown away. Keep it up and your views will climb eventually! Thank you :)
Great repair Tony! Very nice and thorough diagnosis. I really like your style of videos! For this type of drag soldering I'd recommend a BCM2 tip, these have a hole in the bottom of the hoof like you mentioned. That really helps with taking away excess solder like you had to do with that solder bridge. Keep up the good work, I really hope your views will increase from now on 🤗
I actually looked into that, my tips are genuine Hakko (The Ayoue simply don't work) and the one I used in the video IS the hoof tip. But I cannot find a hoof tip with the cavity at the bottom as you say. The BCM2 is a cartridge tip, mine is old fashioned. Are you aware of a similar tip in the T18 form? Thanks for watching!
been thinking of getting the KSGER for a while. My "Ayoue" is... meh. But with Hakko tips it works well. Still, the cartridge tips are cool. I was hoping a sponsor would send me a station for free! LOL!
At first I suspected a quartz resonator, then I suspected that it was a frequency generator, and I was a little surprised that the cause of the problem turned out to be so simple, it's always interesting to learn something useful. Thank you for the video.
Love retro videos. My intro to computers was a graphics presentation system based on CCM. If you're not familiar with CCM, then you weren't into computers 35 years ago! 😮
I love your channel. I have plenty of 80386 boards lying around bcoz I used to have a net cafe buisiness 15 years ago. Your channel is eye openning and nostalgic at the same time.
Missed like that last 6 or 7 videos because I was moving house. Will catch up soonish. As for the general slump, it might just be the effect of summer. It's not unheard of. Keep it up, we appreciate your videos A LOT.
Summer? What's that? Ah, you mean that thing outside of the UK... :D Congrats for the new house, I hope you get all the boxes sorted soon and you can enjoy! Thanks for watching!
I think the comments are working because I just found this channel from the front page and this is exactly the kind of content I love to see instant sub from me.
TONY!!! Love your content, every-time I watch your videos I learn something new, Working with datasheets really helps with understanding of whats really going on. Keep up the great content.
Hi ,I am from India and I always see your videos they are quite motivating and use full .I hope you will keep the good work going and may god help you with whatever your wish is .In my opinion I will like to see half size SBC and full size SBC being repaired by skilful hands of you and some SIEMENS mainboard. In between I was not seeing new video posted by you and was not gating any leads on them recently I was just scrolling RU-vid on my pc and amazed to see your video and watch it which is this one I am commenting to. By time you are better equipped and I like to see that .In the end I will say you just keep doing the good work and god will show you the way.
Thank you for your nice words! SBC as in Single Board Computers? I can try if I stumble on those but more modern stuff is more complicated - and less fun IMHO - to repair. But we shall see :) Thanks for watching!
Crystals that have oscillators installed in the IC usually have 20pF caps to 0V from each crystal connection, sometimes with a 1M resistor across them too. I have seen those caps fail, as well as the IC oscillators failing too, a trick I use if trying to fix something like this is to inject a signal from a signal generator into the IC crystal connection to effectively bypass the internal oscillator.
pity people don't take the trouble to click the thumbs up on your videos, I have been following your channel for a while now and do enjoy your videos and the content they are interesting and fun to watch, thanks.
Yes, it would be great if I had 2000 likes on a 2000 views video :) But I understand, sometimes you just watch and go! Thanks for your kind words, appreciated!
I love your vids, brings back memories from my childhood where I always wondered how this old tech works. And I still do wonder to this day. Thanks to your vids explaining many things, I learn a lot.
Oh, same here! When I was a teenager I wouldn't have dared to tinker with my PC, it took me 2 years to persuade my dad to buy it! The last thing I wanted to do was to break it! :) Thanks for watching!
Awesome video, I'm playing with a socket 7 right now as my first project of the kind and videos like yours provide me with a lot of knowledge! Thank you very much!
I enjoyed this video, and have subbed to your channel :) it’s good to see repair vids that are not just swapping caps and replacing usb charge ports. You appeared in my recommended videos feed so have some hope for the algorithm!
I'm always looking forward to Your next video, cause i thoroughly enjoy each of them. Your positive and humble personality make them a pleasure to watch. Thank You for putting them out there for us to enjoy. Bugger on! :D
This was a great video, Tony. Thanks for your clear and understandable explanations! I just tried a second CPU on a HOT-591P and the board does not respond. It came in its original box with CD, manual and sealed I/O cables and brackets. This video gives me hope that it might not all be lost. I'll have to look into one of those POST cards and how to use an oscilloscope. I really enjoyed this. Thanks again!
I love your content, Tony. And I love the way you tackle all challenges with a smile. This is my favourite kind of content so I'm always going to be watching. 😊 But I understand that keeping the algorithm happy is a challenge. In some ways this kind of content isn't really for "the masses" and I think that's what the algorithm really caters for, and it seems that a lot of RU-vidrs in this space have similar issues attracting and keeping viewers. It sort of leaves you doing it for the love of it more than anything else. I used to order loads of stuff from RS, but in recent times I've been ordering more from Mouser, especially when I have to do a big order. I figure if I'm going to have to order over a certain amount to get free shipping then it doesn't really matter which one I order from, but Mouser seem to have a bigger range of stuff compared to RS as well. But they ship from Texas so it takes a couple of extra days to arrive - RSs overnight delivery was hard to beat when they didn't have a limit.
You are right, repairs are not for everybody - especially those which involve an oscilloscope! The audience is there but it's not huge. I order from Mouser every now and then when they have something nobody else has. RS is the next choice in terms of range but you need £50 I think to get free shipping. CPC is more reasonable with £20 minimum order. I can find my Panasonic capacitors there but for more weird stuff it has to be RS or Mouser indeed. Thanks for watching!
I know the feeling! That is why I have an Apple //e and 486/Pentium boards! My first PC was so slow though I'm not sure I would like to have it today LOL! Thanks for watching!
you need to make some more technical videos explaining how a motherboard works and how to diagnose a fault...very good videos...this is one of my favorites....love it
I have a fledgling retrotech channel, @RetronautTech and all I can say is I LOVE your videos Tony. The thing is, the field is already niche. Its not exactly fashion show videos of young ladies in bikini's if you get my drift. I suppose your videos only appeal to those that like seeing machines repaired. Me, personally, I think its very interesting. I'm not an electronics hobbyist, but I have become drawn into this side of things through a NEED to repair old computers I have bought. I set a challenge to myself, for some reason, to buy broken machines and then repair them. So far its only been an Amiga 2000 and 4000, and the 4000 was a pretty scary prospect, as it cost a bomb AND it had battery damage, and no activity. BUT when you DO get it working, well, there is a sense that you have helped this old kit survive on for others to enjoy in the future. I have personally found your videos to be very instructive. I kind of religously LIKE videos, that I like, as I know it helps people out a lot. My own videos I've seen 30+ watches and only 4 likes. So maybe my videos suck, or people just generally cant be bothered to LIKE videos... not sure.... Keep it up, I think you may go viral at some point, just wait for the blue touch paper to ignite 🤞
You started making videos a month ago, at that time my videos were also doing those numbers - though they were poorly edited and recorded! You have quite a setup and the intro is wow! Fingers crossed Mr. Algorithm will notice you very soon! :) Thanks for watching and for your kind words!
Thanks for your kind words 😃.I'm not too anxious, these things take time. But yeah, guess it can be a bit like keeping a balloon up 😵💫. Er, an odd place to do so, but can I ask your advice? I am probing my Fujitsu PC with a cheapish (£100) OWON 1022i Scope. It tops out at 25mhz (I bought it for 8/16bit machines), but for a PC, I need to check 66mhz, 75mhz etc. The probe IS showing numeric clock speeds of 33mhz and 44mhz, coming out of the machine clock chip. But, I believe that 44mhz should be 48mhz IF the clock chip is working ok (USB clock). I started doing this checking inspired by this video so.. anyway, the chip SHOULD be outputting 66mhz I believe, as that's what a Pentium would normally receive to its clock pin right, 3.5* 66.4mz = 233mhz, the Pentiums speed? But instead, the scope shows 33mhz. Do you think I need to upgrade my Scope to get more accurate readings? OWON do a 100mhz model (£255) but I now wonder if that too will be insufficient in a short while. In a bit of a quandary right now, as maybe that 33mhz is real, the cheap probe is working fine and that's why the PC does not work fully...@@tony359
I wouldn't spend £255 on a cheap scope - You can get a very good one for £400. Yes, I appreciate it's twice as much but the £400 one is a "final" scope for your needs! I have a Siglent, take a look at what Epictronics got, that also looks very nice. Yes, you should have 66MHz at the clock pin - 33MHz if not mistaken is the PCI clock? Have you checked the jumpers? I know it's a silly mistake to do but there is a whole video of mine about spending hours on a board to then realise the jumper was incorrectly set! You can follow my troubleshooting on this video, find the IC datasheet and follow the pins. Those detached legs are very very common! About YT: yes, it takes time! Be patient :)
That was a super interesting repair! Thanks for putting the content up and don’t worry. Sooner or later your channel will (again) get the attention it deserves!
I'm a first time viewer on your channel. Your video poped up on my youtube frontpage. So I think your request for likes and shares are working. Keep up the good work! :)
Seems like it is often one of the pins the closest to the end of the chips that are getting lose somehow. I don’t think you should bother with the ram sockets since it is just cosmetic and they work anyways. I really enjoy those vintage board repair videos, hopefully you have more in stock for us :)
Absolutely, watch this space! I agree with the RAM sockets, it bothers my OCD but also triggers my rational mind that says "it works, who cares"! :) Definitely I didn't want to invest half of the value of the MoBo on it! Thanks for watching!
Great work Tony. I find drag soldering works fine with an ordinary bevel tip, just point the flat side towards the pins(looks like you had the flat side pointing down)
Interesting. That was the Hakko T18-C2, which incidentally happened to be the "hoof" tip I spoke about - but Hakko don't make the cavity ad the bottom. I think I understand what you mean, I shall try that next time! Thanks for watching!
Hey Tony, love your videos! It is always so interesting to see your experience go to work. Especially on older hardware, because they are a lot simpler in their structure, so it is easier for people like me who are still learning, to understand how these things work. I even apply some of your techniques at my student job. Sad to see the numbers declining.. maybe the algorithm doesn‘t know what to do with the „cryptic“ names of the boards/chips in the title. Maybe some sort of contextual algorithm issue. Keep up the good work!
it's definitely a niche subject. I always think that if I threw old computers out of a window I would make more views. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iqAvc0GE_SM.html Thanks for your kind words and amazing to hear about your student job! I'm super glad I could help!
