- I've often been able to "hear" a computer transfer data. While logged
- in from home I like to listen to a particular FM radio station that
- comes in very weakly. When I transfer a screenfull of data (eg ^L in
- emacs) I can hear a very noticable disturbance in the already weak FM
- signal. Sounds kind of like driving under a bridge w/ AM radio. This
- is with an (old) Amiga 1000 and ZyXEL 14.4 modem. Strangely, I never
- noticed this before with my old Avatex 1200 bps modem (same serial
- cable.) Hmm, I wonder if the baud rate is the variable here, or if
- the ZyXEL is not up to spec ...
-
- At RU, I worked with Sun 4/110s. They were networked via thin-net
- coax. I have pretty sensitive ears, and could always hear a
- high-pitched whine when lots of data went through the wire (opening an
- xterm, for example.) One thing that was neat about this is that
- whenever someone logged in to the workstation I was working on I could
- actually *hear* them log in. Nobody believed me of course. Whenever
- I tried to show it to someone they thought I was nuts. :-)
