- I noticed something interesting while looking inside an Amiga
- A4000: The floppy drive ribbon cable hangs right in front of the
- fan opening on the power supply. If the cable were hanging just
- right and the fan was blowing out, the fan could pull the cable
- upto the opening and make the computer overheat. All things
- being equal maybe you want the fan pulling in.
-
- Maybe the reason Commodore won't comment is because it doesn't
- matter. Either that or they will need to recall the earliest
- A4000s and their lawyers told them to keep quiet.

- Just throwing more gasoline on the fire :-)
