Socket 7 Motherboard repair - Shuttle HOT591P

[@adriansdigitalbasement]

Awesome fix Tomy! That type of issue is so hard to find.

[@tony359]

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 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!

Thank you! I also learn lots from your videos, with 25y delay :) Thanks for watching and commenting!

[@JohnnyUtah488]

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!

[@tony359]

It's a good method for when you have stubborn boards with big ground planes and you don't want to melt the connector. Thank you for watching!

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!

[@tony359]

that's amazing to hear, thanks for visiting!

[@alexanderg2211]

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.

[@WilliamDorrepaal]

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 😊

[@tony359]

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 :)

[@mitchkramez]

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]

ahah yes, all that troubleshooting and then it was just some solder - well, that's how I learn thing! Thank you for watching!

[@mitchkramez]

@@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!

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.

[@TheDefpom]

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.

[@tony359]

Good tip! I need to check if my ancient signal generator can reach those frequencies though!

[@arnlol]

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 :)

[@tony359]

[@tony359]

[@RutgerKroeze]

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 🤗

[@tony359]

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!

[@tony359]

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!

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 KZbinrs 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.

[@tony359]

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!

[@ChrisThomas-lt8jd]

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 🤞

[@tony359]

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!

[@ChrisThomas-lt8jd]

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

[@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 :)
