You need to treat that damaged area with white vinegar and a fiberglass pen followed by a good wash with iso, to neutralise the battery acid, otherwise it will continue to damage the traces etc.
5.25" floppy drives are in great demand both working and spares/repairs and some surface rust on the frame won't be a problem. They are relatively rare because they were obsolete by the 486 era and most were just binned as people upgraded to 3.5". I needed one a while back and it took ages to win an auction at a reasonable price. 3.5" drives on the other hand are a dime a dozen.

My comments may possibly help others to grow their skills and also what you can do with these, by doing a follow up build, your experience is valuable in its length and reviving or stopping the waste that electronic products cause, ie reuse of parts into working projects, that give learning and skills, as well as educational knowledge.
I miss my old Compaq 386/25 hz with 4 meg ram 80 meg HD dual scan mono screen, used to have lots of fun in MSD 6.2 with win 3.11, fun memories of my pet hen budgerigar that would fly down and look really comfortable fluffed up sat on the charger. She disliked flip flops, and would fly down and bite peoples toes, fun memories.
I saw Mend it Mark fix some tracks, the other day, by running the soldering iron down each track and adding solder as he went. It seemed to work rather well. Those JFets would have easily caught me out. Obviously taking them off the board and getting them in the Peak component tester is the answer.
@@LearnElectronicsRepair Well I must have seen that as I think I've watched just about every video you've posted 😱 and as I seem to spend more time with you lot than anyone else ! 😆🤣🤣
I'm sure you already have, but I (only my opinion) would pull the RAM on the first one to see if, what may be the memory controller IC, still gets hot. More bugs may be lurking.
I’m a regular watcher, but can i say that, i would have thought it better to look at the value, prior to the cleaning and testing or visa versa! great that the comments and great advice is made, but if as the title suggests, this is a bad batch. perhaps changing the format, so that future techies, are learning procedures and time saving on labour.
Hi Richard. I'm on the hunt for a 5.25" floppy at the moment. Are you confident it's broken? How much do reckon for postage to the UK rather than sticking it in the scrap?
Oh no, another victim to that stupid ISA/PCI diagnostic card, which has fake ISA traces and shorts the ISA bus when connected :( You can tell cos it's that single chip version, the ones with a few chips are real
@@LearnElectronicsRepair PCI works, but not ISA. It's been verified that the traces going to the underside of the microcontroller on that card don't route to anything
Sir , I've been learning English for almost a decade now , I've spoken with American , Australian, South African , people from New Zealand , but your English is difficult to me , it sounds like movies Noblemen living in their huge mansion in a middle of a vast property . I'm curious , where people speak English like you ?

Not much point if the chipset is shorted

I wonder what people do with those 5.25" floppy drives. It should be super obsolete right? Maybe for nostalgia purposes?
@@charmate661 They use their expendible income to build a 486 or Pentium PC of the era similar to what they had as a kid and play old games on it.

I didn't throw it away. I have three or four of these, but I can't test them as I have no media

Yeah I made a video repairing that sort of corrosion using flux. It also worked quite well

just hit the caps with a hammer LOL like in the live stream !!
Yeah that worked better than I expected actually
Most of the clockgen chips are programmable to set the frequencies and dividers so even if you could get a chip it wouldn't work.
5.25 floppy drives do have value about $50 to $80
Provided they work. The chassis was a bit rusty, but to be fair that probably won't hurt the functionality.
havent seen full video Yet, but looking online that GPU in the ATX case half way thru maybe pat of the MX400 Family of GPU's
Heya nice carbooty don't you have a scrab board were you can get the chip for that last MB ?
15:05 The chip next to it looks similar, swap them and see how it goes.
Also remove ram just to be sure.
That P4V800D-x is worth fixing - with agp PCIE - try to cannabalise another board as its worth around $100
I have one or two more of those boards which are working

OK can do on the next booty video

Actually I didn't put it in the trash. I have at least three of them here but no way to test them (no media)
@@LearnElectronicsRepair Very wise to hang on to them. I have a bunch of discs I need to read.
there was 8 sim slots on that motherboard not 4

@voodler So why did the stupid ISA/PCI diagnostic card work OK last time I used it on a car booty video sometime in the last couple of months or so?
@@LearnElectronicsRepair PCI works, but not ISA. It's been verified that the traces going to the underside of the microcontroller on that card don't route to anything
If they don’t route to anything then how are they shorted? I have one and not had any issue.
its dirty
