Up to now, most of the things I've done with my A500+(s) have been bad

When I first got an A500+, it gave me a green screen of death when I booted it. Except I didn't know this because for some reason I'd decided that the MONO output was actually colour output (resulting in it being a green screen of death).
Dad and I opened it up to find out why, finding a lot of what seemed to be verdigris (battery leakage?) all over the motherboard. In attempting to clean the chips, I managed to remove some of the metal contacts in Gary's socket, probably make the situation far worse, and what we ended up with was an Amiga that didn't even turn on properly.
So, I'm now on my second A500+... and, using the stack of cover disks that came with the first one, I managed to total 2 floppy drives before I realised that many of the cover disks were so degraded that they were destroying the drives. I also managed to total most of the Workbench disk copies that also came with it, including the original, mostly by trying to write to the already barely readable disks... one of the disks died because I had the A500+ too close to a wall and accidentally pushed the eject button into the wall while the disk was being accessed.
However, I now have a working floppy disk (I use one of the dead ones, stripped so I can spin it manually, to check disks for catastrophic damage), a working copy of Workbench, and my Amiga appears to be happy and not hold a grudge against me for being such a Mexican Bee Man to start with...
