- I think that's what caused the *big* delay between ECS and AGA. If you
- go down to the bare hardware, then you don't just rely on *where* the
- custom chip registers are... you're also making assumptions about their
- *meaning*.

- Very funny. Just imagine there's some device connected to my
- serial/parallel/joystick ports, that expects certain lines to be
- _input lines_ (seen from the computer side). Now, some semi-smart
- #+!^"+$ like you comes along and (accidentally) makes some of those
- lines _output_, causing an excessively high current to flow.
- *POOF* there goes my hardware.

- Never happened to me, but it's possible. You could easily destroy an
- audio/video digitizer that way. Of course you could protect those
- peripherals (actually some *are* protected :-), but you would still
- kill one of the CIAs.
