- Ground thyself. You are the most dangerous thing that can happen
- to your electronic equipment. Just spinning around in a chair can
- develop damaging static electricity. Always touch something at
- system ground before anything inside your Amiga's precious guts.

- It is possible that you have popped a fuse on your motherboard.
- The fuses look like green bodied resistors that are marked 2A, 4A
- or some such. Check them first. They should conduct. If one is
- blown, you can bridge it from end to end with a new one instead of
- going through the ordeal of motherboard removal etc.

- The Amiga 3000 uses the same CIAs as A1000, A500 and A2000.
- The chips are 40 pin DIPs and are socketed.
