Reptile,
Congrats on the A500+. If the broken Amigas seem too much, we have members skilled in repairing and replacing, as well as people who will gladly buy them.
If you have a P4 era PC lying around, migth I suggest Amithlon? Great for older PCs, and it runs real Amiga applications at very good speeds.
If you have about 150-200 bucks, you should check out MorphOS, for PPC Macs. Very good, mature AmigaOS successor.
There are vast resources and helpful members here, let them know what you need anytime.
