So I got this hit on a wanted advertisement on Craigslist. I was after an Amiga 2000 system to go with the Pangolin QuadMod16 I bought off of someone via Reddit. Oh yea, I forgot to mention, QuadMod16 in the hizzy! As I feared. As I expected. As I somewhat wanted (to save a computer from death.) The A2000 time/date/config battery had wicked it’s corrosive guts into the system board. The system booted though, so I mostly did my best to neutralize it with vinegar and baking soda.
I cleaned things up. The system was very very nicely loaded, including a Toaster, DPS TBC, DPS PAR, DPS s-video to toaster board, 030 accel, fast ram upgrade and more. I replaced the hard drives (one had failed, one was working but crazy loud) with a SCSI2SD. The one trick is the SCSI2SD boots slower than the Amiga so a soft reset is required after power on to get the system to load from the SCSI2SD board.
The toaster works but I have no way to sync up sources, the TBC-IV seems to not work. The PAR works. Most software seems to work via WHDLoad, although one or two guru meditate.
The corrosion inside is fairly bad, and I fear that in the future this system might still fail. The accelerator that takes over the role of the main CPU might be the saving grace. Also, the ISA slots have corrosion on the connectors. Seems like it might be okay, but time will tell.
The monitor will need to be pulled apart and switches cleaned, and the focus is off quite a bit. Probably could use a recap but that seems like a daunting task.
The keyboard restoration is in another post, it took a lot of work.
Overall I’m thrilled to finally have an Amiga 2000 with the proper specs. The QuadMod16 is another project, it didn’t seem to work or the software is locked to the board — I’m going to ping the original creator for some insight. But Amiga is rocking! My 600 suffered a pretty bad issue and I’m having someone else do the repairs. During the process of 2000 restoration I took a stab at two dead A500s I have, and was not successful in anything after a good number of hours of work. I found bad RAM and replaced but past that neither work at all. Oh well.
One thought on “Amiga 2000 Motherboard Clean Up”
Great work for the A2000 Ethan!
Could you please explain how you cleaned the motherboard?
Mine got the bloody battery leak and after cleaning I got a black and a green screen 🙁 then the power alimentation broke sadly 🙁
