Jan, your Amiga restoration videos are arguably some of the most realistic there are. You don't seem to hide much of the bad stuff, which make your repairs more realistic. Keep up the great work!

Some Amigas were built with single-wipe DIP sockets. These are the ones notoroious for failure - I normally suggest replacing them whenever I find them! The PLCC socket isn't bad, but often the chip can get well and truly stuck in there. I've had them where it's impossible to remove the Agnus without desoldering the socket, and breaking it away from the chip!

13:20 i doubt Commodore used a dishwasher, but the machines that clean boards after assembly work very much like a dishwasher internally, so thats probably where that saying came from :) The only thing about using a dishwasher would be you would have to ensure there is no softner salt in it, as that would very much corrode things!

Nice restoration Jan, just a suggestion, remove all chips on socket before washing a board, then use at least a hairdryer to remove most of remaining liquids.

@stevesether Жыл бұрын

That's will work, but the alcohol method is easier and safer. The advantage of using alcohol is it easy mixes with the water, and makes any remaining water evaporate more quickly. Alcohol also has less surface tension, which makes it spread out more easily and evaporate even more quickly. Alcohol also has the advantage of being non-conductive. It's safer because you could heat something up a little too hot with a hair dryer. With alcohol, there's really zero risk.

@mal2ksc Жыл бұрын

@@stevesether Just don't combine the alcohol and the hair dryer. Alcohol vapor is quite flammable, and the flames are very pale and hard to see. In school, setting a textbook on fire from several feet away was a common trick. (Don't worry, it only ever scorched the paper bag covers we were required to put on the books.)

Nice Amiga 500 restoration :) Mine seems to be the same way, keyboard is more yellowed than the case. Removed the battery from my 512kb RAM expansion already in the 2000's, when I noticed it had just started leaking, catched it in time so no damage was yet done, and it still works :)

Using water is quite common, even today. A relative worked at a medical equipment manufacturer. The boards they assembled were washed in water and simply air dried with compressed air. The only thing a person needs to spend time on is hidden areas where water can stay, like connectors, sockets, and the underside of BGA type packages. Just make sure it's dry and you're good to go.

You can actually buy carbon paint (mostly sold to repair remote controls that use similar carbon contacts) and apply that with a small brush. I've never used it myself but supposedly it works pretty well to renew the carbon layer.

Ich habe auch einige PCBs rumliegen, die mal gründlich gereinigt werden müssten aber ich trau mich nicht. Wie lange sollte man die PCBs nach dem Waschen trocknen lassen?

@JanBeta Жыл бұрын

Ich lasse die PCBs gewöhnlich nach dem Spülen mit Alkohol ein paar Stunden aufrecht stehen, das reicht meistens. Wenn du sicher gehen willst, kannst du sie über Nacht oder einen ganzen Tag trocknen lassen. So lange kein Wasser mehr auf dem Board ist sondern nur noch Alkohol, gibt es aber eigentlich keine Probleme. Geschirrspüler auf niedrigster Stufe (und ohne Geschirrspülmittel) geht angeblich auch gut, habe ich aber mangels passendem Gerät noch nie probiert.

@Jan Beta, Maybe you could put a simple waveform generator connected to small speakers under the sink. It may even possible that the magnets of the speakers will hold them to the steel sink. This might allow you to make a poor mans ultrasonic cleaner.

I'm planning to try building something like that sometime. Should be easy enough. I won't use the sink probably but a separate container.

Hi Sir, can I suggest to remove the solder from where the battery was and place a CR2032 holder, remove the resistor directly connected to the + and place a diode? To be different why not try plastic welding using your soldering iron the parts instead of the glue method? Ditch out the old floppy and place a nice gotek?

@mal2ksc Жыл бұрын

Once you start using a soldering tip to melt/cut/shape plastic, it is pretty much finished as a soldering implement. I have a worn out iron of uncertain temperature that I use for working plastic, because I'm not willing to sacrifice tips on my good iron. It also stinks something awful and burns the eyes. Even ventilation that is adequate for clearing fumes from soldering will barely put a dent in burning plastic stink.

@JorgeCarvalho_web_dev Жыл бұрын

@@mal2ksc yes, that would make the video more interesting, also the soldered plastic could be a more permanent and robust solution. I never damaged my soldering tip when setting to 150º C to melt slowly the plastic. I saw an extreme A2000 case restoration and even some small metal clips were used to give a good bond between the two parts. Sorry my english, it is not my native language

@mal2ksc Жыл бұрын

@@JorgeCarvalho_web_dev I will admit that I have never tried melting plastic with an iron that has temperature control. I might get better results that way, but I never wanted to sacrifice a good soldering tip. If this won't ruin the tip, I would be more willing to do it. I bet it still smells awful though.

@@JanBeta: Yeah, it's only correct with something like a lead-ACID battery (auto, boat, etc.). Why is it such a commonly mistaken term even though most batteries are NOT acidic? Why is that what caught on wrongfully instead of base/alkali, even though that's what most batteries are?

Great project as always Jan! Love your content. I hate to correct you on your English use because you’re really fluent. Saying “At first” is different than saying “First”. “At first” usually denotes that something’s status will change, usually to the opposite. E.g. “At first he seemed nice” (with the implication being that he wasn’t really nice and only appeared nice on first appearance). Apologies for the correction. Looking forward to your future projects!
