@MrTBoneSF 6 месяцев назад

A few months ago, I found an Apple IIc at a recycling center in a very similar state. The bottom was just a brown mass of rust and goo. After seeing all your videos, I thought "what the heck" and took it home. Inside it was even worse. The RF shield had completely eaten through in most places with just a tiny bit of shiny metal left and all the ports were solid rust. The infamous keyboard rubber mat had turned to dust. Still, I'd seen you recover worse, so I pushed on. The floppy drive had rust and insect corpses pouring out of the slot and there was a disk inside that had fused to the innards. Surprisingly, the rubber belt (that usually turns to dust or goo) was intact. Long story short ("too late!"), after a lot of de-oxit and IPA and rust remover, I plugged it in and it mostly worked fine! The biggest shocker was after thoroughly cleaning the floppy drive and re-greasing the components, it also worked. This was the ultimate goal since I had a stash of about 40 floppy disks from the mid-80s with no way to read them. 5 1/4 floppy drives are getting very rare and ones that can work with Apple II disks with something like a kryoflux are even rarer. And another shocker was of the 40 floppies only two were unreadable. Not bad for 35+ year old magnetic media. It was quite a joy to re-discover some computer projects from my grade school days and archive them. Now I can run them in an Apple II emulator and show my nieces and nephews "This is what your uncle had in school when computers were new". So thanks for the inspiration and maybe check if that floppy drive still works. You might be surprised.

@SianaGearz 6 месяцев назад

Mouse and that mouldy joystick are worth a shot as well. Though i guess it's good to disassemble it outside and maybe dip it into miconazol just in case :D

@orbitalgolem91 6 месяцев назад

Curious how you archived the floppies? I have boxes worth also from the '80s. Still have my Apple ][ Plus, //e, and IIGS, but would be good to be able to access the disk images from an emulator.

@the_kombinator 6 месяцев назад

I would be careful putting anything into that drive that you care about - throw some disposable diskettes at it first!

@eDoc2020 6 месяцев назад

@@orbitalgolem91 If you have working Apples you can use ADTPro to transfer data to a modern system. You'll need a serial cable but this shouldn't be hard to obtain.

@MrTBoneSF 6 месяцев назад

@@the_kombinator Exactly what I did. I got some blank disks and then transferred known good disk images from a PC to the Apple IIc via ADTPro. Those booted fine. Then I had ADTPro read the same disk and transfer that image back to the PC and verified it was byte-identical to the original. Then I went through my disks in order of least importance (just in case the functionality was intermittent) and imaged them to the PC. I'd seen videos of people preserving old magnetic media where as they were being read for the final time, the oxide would come off, so I acted as though I had one shot to do this. In the end I had a lovely time capsule of the 80s including an ancient AppleWorks database of my old comic book collection (and realized the box is still buried in tupperware bin in my parent's basement appreciating in value).

@eDoc2020 6 месяцев назад

No, clean them before doing other _troubleshooting._

@devil5051000 6 месяцев назад

They are rotten, cleaning will help but the rotten sockets will likely cause instabilities later on. Especially if the Amiga is back in its case (it can get cozy warm inside). They all have to go. Sockets are a common problem on all THT-Amigas, even the ones that have not spent many years outside. ^^

Tonight Adrian made me sick to my stomach as he said battery in the memory expansion. Run to the basement I checked my Amiga and sure enough the battery in it just started leaking thank God it did not touch the board!!!! Lol. 😅 Thank you Adrian!!

@dru6809 7 месяцев назад

Another patient brought back to life at your Amiga hospital. Amazing work!

@danaeckel5523 6 месяцев назад

I do appreciate Adrian's taking the "long way" to fix something in an attempt to teach us. This way we can see how the system reacts when various components arn't functioning properly. The final lesson if you find a computer in this type of condition, check and clean the chips and sockets before bothering to turn in it. Granted Adrian could have done that and gave us a 10 minute video but then we would have missed out on quite a bit of info. Amazing how he can be given a computer from somebody that sat on a shelf for years, and turns out to be a total bust, then dig up some thing from a field and up and running within a day. Boggles my mind.

@mwwhited 6 месяцев назад

To help your toothbrush action you should get an old/cheap electric tooth brush. When the battery died in mine I bought a new one, replaced the battery on the old one and made it a permanent fixture on my electronics bench. It works really well for cleaning flux and corrosion.😊

@watchmakerful 6 месяцев назад

For this type of sockets, always clean the chip pins from BOTH sides, especially from the inner side.

@kepamurray1845 6 месяцев назад

It never gets old seeing you get excited when it starts working. Thanks Adrian.

@FordGT40MkIV 6 месяцев назад

I noticed a resistor network next to the Gary chip surrounded by corrosion and thought surely it was causing grief. Apparently not! Go figure. Looking forward to part 2.

@jimmy2drinks 6 месяцев назад

I kept looking at that & thinking the same thing...

@frenchshark2000 6 месяцев назад

To correctly boot, the OVL (overlay signal) should work. It enables the Kickstart ROM overlay at address 0 through Gary's address decoding (OVL -> ROMEN). The OVL signal is coming from one of the CIAs.

@Lukeno52 6 месяцев назад

I think a lot of people originally found this channel from that C64 video - I know I did. Always fascinating to see that things like this can still be salvageable!

@BestSpatula 6 месяцев назад

My high school's TV studio class was still using an Amiga 500 and Amiga 2000 Video Toaster in 2002 when I graduated. We used the video toaster as a switcher and the Amiga 500 was used for creating title graphics. I have no other experience with this platform, and I very much would like to see more about it. Thank you Adrian! ❤

@DerekLippold 6 месяцев назад

Video toaster was in use for a surprisingly long time.

@kattan2006 6 месяцев назад

The first thing to do that every Amiga 500 owner should know is to re-seat all custom chips. Take them out and just reinsert them. Better yet, check all socketed chips on a working Amiga motherboard. Regardless, I like all the videos you do

@jNetDowling 6 месяцев назад

Adrian please stay exactly in this style of troubleshooting what you mentioned at the end. It is exactly why I like your videos. You dig deeper and deeper until you find the problematic component. Also I like your comments on findings while you edit and cut the stuff (this ROM topic). Stay in this mood and style and your videos will be fantastic as they were in the past. I also found your channel with the field found c64 and now you have a field found Amiga 500. Fantastic Thanks for this content, best wishes

Omg, stumbled onto this channel and video, and it’s brought back so many memories of my A500 and the A1200. It’s how I started as a software developer. Absolutely loved watching this video. Well done good sir, bringing life back into old hardware. I tip my hat to you good man.

@sluxi 6 месяцев назад

Great work Adrian, love seeing Amiga rescues. It is pretty surprising how little was wrong with it, some videos that I have seen with battery corrosion have been so much worse.

@LandisSeralian 6 месяцев назад

I recently received and Amiga 500 that was sitting in a barn in germany for 30 years and survived shipping to the US, it was in similar (though not quite as bad) condition as this Amiga and it's pretty amazing how much a good cleaning can take these old machines from completely non-functional to running perfectly! Always great to see these machines restored! ^_^/

@brooknet 6 месяцев назад

I enjoyed this journey into Amiga hardware. I'm glad that you looked at the boot process in detail, as it's always been mysterious to me. Not only do the 'failure colours' vary between OS revisions but there is so much that is undocumented - and that weird purple early boot screen was a classic. Also, the process of investigating the problem often makes it a) get worse or b) disappear - a 'heisenbug'. I've seen many of these while debugging electronics.

@asimcannon4090 Месяц назад

Love the share!! When the computer booted I was just as excited as you!!

@marvk 4 месяца назад

I know it's a small thing but thank you for linking to the next parts, not just mentioning them in the video! Very refreshing to see. So many channels on RU-vid make you search though their catalog of videos without parts numbers to find some mystery part 2 that may or may not exist.

Adrian : Thanks for leaving in the whole analysis process of the diagnostics (and of course you needed a video after all this effort 👍), but it does allow me (a complete non-touching-old-computer novice) viewer to see your whole process of checking chips, reading schematics, and testing pins, etc. Thank you... also, I can imagine that was a video editing nightmare to keep all those "attempts" and secondary footage synced in your edits. Well done.

If you can find some in your area, get an aerosol, drip can, or spray bottle of Kroil from Kroil Labs (formerly Kano Labs). Expensive, but one of the best penetrants on the market. That may have made separating the original RCA jacks a bit easier. Kroil is an "active" penetrant, and will bust that rust for ya. Tons better than WD-40. Some CRC Zinc-it cold galvanizing spray will take care of those metal surfaces once the rust is removed with a wire brush or that dremel tip you're so fond of. A little sprayed into a cup and then brushed on will get the small stuff like D-sub shells, but be sparing with it when brushed on. Your approach to troubleshooting is systematic - don't listen to those who advocate a "shotgun" approach. I would, at some time in future, consider replacing some of the sockets (notably the PLCC socket for the Agnus) that were really crunchy , but for now all seems to be working. I'd also think about installing sockets for the RAM to make future troubleshooting easier, but that's just me. Do consider getting caps of the correct value to replace those 1,000 microfarad ones you installed. That would likely be better for the long-term health of the board.

I'm definitely curious to see what, if anything, you plan to do about the beyond-repair metal shields.

@choppergirl 6 месяцев назад

You got to know not everybody loves the Amiga, when they leave it outside for 20 years. I found a Vic-20 once in a landfill. Brought that puppy home, wrote a little cassette disk OS boot loader for it, and gave it away to a friend. They then abandoned it yet again and left it behind when they moved out of an apartment. I was so mad. I think I went to pick it up when the office manager called me. After that I probably gave it away yet again in a care package to some poor Commodore nerd on the old ISCA BBS. By that time I was swimming in hundredss of computers.
