12:41 I'd recommend making a small slit in the wire coating with an X-Acto knife before heating it up, That way you know where the coating is going to separate. Also I usually only do that if the wiring is serial - ie, I'm connecting the same wire to multiple spots and I don't want to cut and splice it.

@Cherijo78 2 года назад

First thing I thought of seeing that socket was my father's ancient soldering gun with the trigger light. Those things put out 100w+ at a go. Great for thick cable wiring, not for boards. When I was a kid about 10 or 11, I tried using that gun on a circuit board to add a wire on for and that burn type happened. I laughed so hard seeing this here.

@kpanic23 2 года назад

Those machined precision sockets are great for new chips but are really bad for desoldered parts. They can even get damaged when there's an excess of solder left on the pins. That's why I almost always use dual-wipe sockets when in doubt. They are way more reliable than the cheap single-wipe ones Commodore used and are also mechanically tolerable to desoldered and/or otherwise abused parts. Add to that the bonus of being way cheaper than machined sockets... Dual-wipe sockets have never let me down. The only way to ruin them is by ramming too thick of a conductor in them, like some ROM adapters, Kernal switchers and so on, they might get bent and not work with the flat pins of regular chips any more.

@johnbos4637 2 года назад

I almost always use dual wipe sockets because they contact the pins better. Look at a machine pin socket that has had a dip chip in it and you'll see a groove worn in the hole. Once the chip has been removed and replaced a few times the machine pin socket becomes sloppy whereas dual wipe sockets will hold dip chips well as long as they are not abused by inserting an adapter like you said. For desoldered chips I always use wick to remove the bulk of the solder then just sand the legs with 400 grit sandpaper then the legs are smooth and the chip slides in easily and can be removed without pulling pins out of the socket.

@atomicskull6405 2 года назад

Fun fact, later C64 PCBs were made from compressed paper fiber with a coating instead of G10 in order to cut costs even further. Though at least Darth Jack did it to actually lower the MSRP rather than just keeping prices the same and pocketing the difference. He might have been an assh*** but he did believe in selling affordable computers.

@bobblum5973 2 года назад

Seeing circuit board damage brings back fond(?) memories of repairing CB radios back in the 1970s. People would do so many things wrong; not quite to the point of a propane torch, but plenty of cases of acid (plumbing) flux, 100+ watt soldering guns, you name it. Combine that with poor quality PC boards and I saw a fair number of burned and delaminated PCBs, broken traces and feed-thrust. Kudos to you Adrian for sticking with it and finding the problems.

@larsenmats 2 года назад

This is why I mostly use dual wipe sockets instead of machined sockets. The dualwipes makes much better contact with desoldered chips that has short legs.

@SidneyCritic 2 года назад

I like dual-wipe, but I think they can suffer capillary moisture retention that oxidises pins. I think the machined ones are interference press fit that are too tight to let oxygen between them. Basically it's easier to make contact with DW, but if a machined one makes contact it's permanent.

@Dukefazon 2 года назад

Bil Herd said in a (now) old 8-bit guy video that you should always use dual wipe. This burned in my brain. For some reason I don't trust those hole-type (machined?) sockets.

@8bitwiz_ 2 года назад

What happened with the original socket was probably way too much solder was used, and it got sucked up into the top side of the pins. Maybe too much heat warped the plastic a bit too. I prefer to use round pin sockets only with round header pins, but round pin headers are great for making daughterboards for wipe-pin sockets, such as a 2513 to EPROM adapter board.

@ralphj4012 2 года назад

Messy, but you can push a conventional wipe-pin socket into the turned pin socket and then fit the original 'short-pin' IC.

@bobblum5973 2 года назад

Adrian, for the chips with narrow, short or damaged pins, I have put one into a machined-contact socket and soldered it into place. The chip & socket header assembly can then be used in another machined-contact socket on the board. I learned to do that at work years ago, when needing to swap test EPROMs frequently. I used Augat brand sockets, not sure if they're still around or not. Only once or twice did I have an issue, that was where the little cylindrical contact inside a socket pin was missing.

@jason50146 2 года назад

I have problems with machine pin sockets. So much so, that I can't trust them and have switched back to dual wipe sockets. Just as you observed, they will sometimes fail to make contact with all the legs on pulled chips. In addition, when removing and reinserting chips during troubleshooting, contact will become intermittent, requiring you to push down on the chip. I have also observed that chips are more likely to pop out of machine pin sockets. I don't have these problems with quality dual wipe sockets. BTW - seeing all the burning made me laugh...poor board. Looks like a smidge too much wattage on the iron used for that "repair". I also love the heavy duty bodge wire. Reminds me of old times.

The damage was also totally invisible and the traces on the Speccy are really, really fragile and exposed as mine lacks a solder mask.. I was about to replace all of its upper memory chips when I discover the broken trace. Good thing I did a full continuity test first; face palm :-)

@tony359 2 года назад

when I was a kid and I was trying to solder without anybody telling me how to do, I didn't know flux was important - and didn't know flux was in the solder itself. So I would melt some solder on the iron's tip and then (when the flux had all burned away!) apply it on the joint/component. Since the solder would not flow, I thought it was a temperature issue so I would get the biggest and most powerful irons I could find. The results were more or less what you saw on that poor board - well, maybe without the brown patches! :D Great video as usual!

@cymryman 2 года назад

That's why you should use liquid flux. Then you can place it on the lead area and be more precise with it. Particularly with thru-hole parts as the flux will fully penetrate in the barrel and not burn off right away.

@awilliams1701 2 года назад

I'm not great, but everytime I messed up my C64 repair I fixed it. I have a bodge wire where I removed a trace. Then again I have a 2nd one where I lifted a trace, but it was still attached, so I didn't bodge that. IT's on the cartridge slot. I had to replace it. De-oxit helped..........until it didn't. It got to the point where de-oxit was lasting less and less until it did nothing. New slot = fixed.

You can clean up desoldered pins a bit by (quickly) using a desoldering gun on the pin (I mean the type that has a combined heating element and desoldering pump) then applying some flux and reheating the pin to smooth out the remaining solder, then clean off the flux. You end up with a clean lightly tinned pin basically a tin plated component leg.

@Renville80 2 года назад

One thing I tend to do with plated holes when cleaning up after a poorly done prior repair is to use a pushpin as a mandrel to push any potentially loose barrel plating back into place, and the pads on that ROM socket would be a prime candidate for such a step. Another step is to use a small dowel to press down the edges of pads that may be beginning to lift. Neither step will restore the lost bond between the copper and fiberglass, but will go a long way to improving the post repair appearance.

We called making one's own trace, or by passing a PCB trace, a "rework." I can't remember anyone calling it a "Bodge." Sometimes someone would say a rework was a "Kludge." Years ago I offered up my own word for it, which I called a "Ricky." The urban dictionary had that for awhile. I see its not there any more in definition.... but a Ricky was some sort of rework, BADLY DONE. It was shorthand for something that had been reworked in a poor manner. There were levels of Ricky-ness. If the device had been totally Ricky-ed, it meant it was not worth the time to fix it. "Ricky has been here," meant there was a chance to repair it. Love what you do with the C-64s and bringing them back to life. One might suggest that it was the last understandable PC.

Funny you mention a torch. Was at a hamfest and a guy was selling 1 lb grab bags of parts from boards. Talking to him for awhile and found out his technique to remove parts was to heat the board with a torch and rake over top with a wire brush till the parts fell out. I didn't buy anything lol

Holy damn, I wouldn't buy anything either.

Really enjoyed this video! I get to see diagnostics and repair techniques that I need to learn how to do, like using probes and oscilloscopes and correct sized bodge wires. Also want to know to how to use those replacement through hole via kits. Still have lots to learn! Congrats on getting this to work. Repairing a failed repair from somebody else is ALWAYS the worst.

19:48 - I must've missed when you upgraded the tester display but man, it looks so snazzy with that OLED.

Looong time ago I replaced a VGA port on a mobo with a torch and Works for 5 years until my cousin sell it. Good old disaster days!

Impressive! Wow I fixed some (and probably damaged some boards as an apprentice fixing C64's in my day) Takes me back and YOU did very well repairing that mess!

Are you sure a Dalek didn't (try to) exterminate, er, I mean repair that board? Great Save!

Love Adrian’s enthusiasm. I wish I knew what he was talking about 1/2 the time 😂

Una riparazione eccezionale. Ti seguo da tanto e come te condivido la passione per la tecnologia e l'informatica vintage come potrai vedere dal mio canale. Nonostante non abbia mai capito l'inglese, grazie alla tua pronuncia fluida e chiara riesco a seguirti nei tuoi video e a capire quasi tutto. Sei veramente bravissimo. TOP !!!!

Ok, so look at the channel called Trevor’s Work Bench. In a Video form April 2020. He uses a butane torch on a C64 board to remove chips. I was shocked seeing that.
