NiCD/NiMH batteries leak when they are old and severely discharged, and this commonly causes damage to vintage computers. Here is a 286 and a 386DX motherboard that had the battery leak. Are they ruined?

The space where the ram would be sticking up into was usually filled with disk drives and maybe a hard drive. Though, I saw mostly machines that had that board, if they had a hard disk, it was a disk on module setup.

I always thought the 286 didn’t get enough love. I’ve even seen it denigrated as merely a microcontroller or basically just an 8086. Sure, its protected mode wasn’t forward-compatible and it didn’t add as much new stuff as the 386 and 486, but it’s still a neat stepping stone. Lots of people often go from talking about the 8088/86 right to the 386.

I did development like this motherboards with 486 up to Pentium III: one of my tools was a "BIOS" that only contains "Inc content of io 80" and jump back in "RESET vector" helps a lot in cases like this. You cannot read but measure frequency on data lines. Check voltage, clock and reset like you did is a good start. If this still does not work: mostly no fix possible. Btw: Having most adresslines high at BIOS is normal short after reset (reset is equvalent to a jump to FFFFFF0) as far as I remember.

Hi Adrian's Digital Basement. I hope you are keeping well. I have a similar acorn archimedes A3000 Board with battery damage, and firstly let me say corrosion like this doesn't do any boards any good. The acidic or alcalinic fluids seep through the thin layers of copper or other metal tracks and render them unrepairable. I Know there are people on utube who have repaired similar boards to mine. He had quite a few whole computers so he could swap bits. I didn't. Good luck with yours. It all depends how long its been left to rot and how good the board was in the first place, and how pedantic and clever you are. I have put my one to one side for now untill I have accumulated more Knowlege or time. I live in Nottinghamshire England by the way. and have worked in an electronic sevicing center in Nottingham but I have now retired and just do bits to keep my hand in. Kindest regards Phill W

Many years ago I swapped the BIOS chips on an IBM 5170 AT with AMI BIOS ROMs from a broken generic clone motherboard. The main advantage was that it contained a ROM-based setup utility, rather than having to boot the setup floppy every time as the IBM had no battery in it. I seem to recall that it also allowed me to use 3.5" disks in 720K format, where the original IBM BIOS would only support 5.25" drives. I sold the machine a few years ago due to shorted tantalum capacitors on the board, and a lack of space and time to do anything with it.

Never had a single problem with it, but my ST-4096 (80M MFM drive formatted for about 150 megs using a sequel erll controller) made some really hideous sounds when it died in '92. The dtk board might still be out there somewhere, who knows. Those '286s were freaking workhorses. Got a bit warm, but never needed a heatsink, unlike my current rigs, both delidded, using conductonaut & kryonaut, with 240mm AIOs, then again, this 8086K is a wee bit faster.

I have a very similar 386 board, a SY-011, a 386DX-16 with 8MB on board and the 386 copro... it also is currently suffering a hangover from the "battery juice." Mine at least tries to post-- it stops at post code 0x20, and then beeps and shows a message on the screen: "CMOS INOPERATIVE." I'm at the stage of trying to figure out if I have any bad traces. Seeing what you did here helps a lot! I'd gone a long time without an EPROM programmer, but this repair has finally pushed me over the edge. Wanted to be able to read the BIOS and make sure it wasn't corrupted. If anyone has dealt with this particular error before, tips are welcome! I do have a related question: So when these Varta batteries do their worst-- and cause massive corrosion all over the place-- what's going on there? I don't mean right around where the battery is, and gravity could have pulled the battery acid "down hill." I mean at some distance away, like pins inside a nearby slot, or pins inside a chipset socket? It's almost like the battery has a "vapor" that is evaporating and travels in the air and condenses back onto metal surfaces?
