In this episode of Amiga Retro, I will perform the dreaded SIMM Socket replacement of the very breakable, cheap Commodore SIMM sockets on my Amiga 4000. Let us begin...
Excellent tutorial on how to replace memory sockets and how to figure out what was disconnected afterwards. Owning a 4000 is becoming a rich man's sport nowadays I keep looking but they are always more than I can afford. So I hope yours lasts a long time.
Commodore was thinking about the future. Amiga enthusiasts would need something to make RU-vid videos about, hence the crappy SIMM sockets. See C= thought of everything. :) Cool video!
I clean my boards by soaking them in 91% IPA and then shake them outside to get rid of the IPA and then follow that up with my hot air gun to drive off what little water remains. If the board has been damaged by a leaking battery or a leaky cap, then it's a white vinegar bath after the recap, a rinse in plain old tap water, and then off to the IPA bath. It's a trick that I picked up from the Jamma guys, and I have seen it done by VFD drive repair shops. So far twelve boards, and no problems.
Hi, can I install vertical SIMM slots so I can use double-sided SIMMS, I will be modifying the motherboard using a hack from one web site to use bigger memory?
You may have room if you do not use the bottom slot of the riser card. Though, I cannot say for certain. I can check when I get back home at the end of the month, if you can wait that long :)
If you have a de-soldering station such as I used, the process will be relatively painless. Do not use de-soldering braid, an unpleasant experience will await you :)
I like the content, but not the presentation so much...I have an A4000 which needs mem slot replacing, so this video is a lot of help, thanks! Could you perhaps share in this videos more info, what the mem slots spec is, and where you bought them? Maybe a manufacturer code? Im also a budding RU-vidr, so, my advice is... When recording, try to not talk about the process too much, or at all if you can. I know, hard... But saying you are going to move a tripod, or that the autofocus is problematic, is pulling your quality right down. Just like on TV, the "camera man" should be invisible, the focus should be 100% on you, and what you are showing. So... how to avoid, well, you cant 100%. But maybe these fiddly bits could be trimmed out in video edit? Sometimes when I talk, I make mistakes, and I just cut them right out when I can, or maybe fast forward through these adjustments. But Id just cut them out. Makes for a shorter video, but which is MUCH more to the point. When soldering, could you put the camera opposite you? Not over your shoulder. Tricky, I understand your place is small... But it would make it so much easier for you to film unobstructed. If you have a new iPhone, I assume you are filming with one? The get the Protake video camera app. It has a MANUAL focus (manual everything) which will make those macro focusses totally locked. That, plus some setup (off camera) would make the soldering sections a lot less chaotic. Anyway, constructive criticism. Hope you take it as such :) And I look forward to seeing future videos.
Thank you and thanks for watching. I will definitively take your suggestions into consideration. I really need to use my overhead camera setup more often, this would minimize the "Tripod Incidents" :)
The socket I did not change is for the 2MB of ChipRam, which was in good condition, and since it is needed to boot the computer, will seldom need to be swapped out or upgraded.
@@amigaretro4765 but the plastic will get older and more brittle,and will brake sooner or later,and then you have to do the work all over again,it may take 5 years it may take 20 years,but it wont last forever,and who knows maybe that part is not available then.
Understood. I do have spare sockets, I have been debating on changing it when I change all 5 on the other A4000 I have. Once you get used to how long it takes per socket, it's not too bad :)
@@amigaretro4765 in 1983 I did the NASA 'high reliability soldering course' The first part of the course was a training film made by NASA, and the first thing we all balked at was when the narrator said sodder lol the in 1987 I did a multilayer printed circuit board repair course, and again in one of the training films the narrator said sodder.....oh and sorry for calling you a yank, I know most Canadians hate that
