[vcf-midatlantic] Old computer I can learn to repair?

[Benjamin Krein]

I just got my first ever oscilloscope (Zoyi ZT-703s) but I have a problem -
I don't have any broken computers! :)  Anyone have any old computers that
are repairable they want to get rid of?  Probably something 8-bit just
because I'm an absolute beginner.  I'm also thinking something more common
just because resources will be easier to find.  Here's my wish list but I
won't look any gift horses in the mouth!

1. Commodore 128
2. Atari 400(xl)/600/800(xl)
3. Apple IIc(+)

I've always wanted an Amiga (500) but I'm not sure if that's getting too
complicated or not for the scope I got?

I'm in the Philadelphia area.
