[geeks] ADB to USB or ADB to PS/2 converters

[velociraptor]

AFAIK, that's not the case.  A quick google turned this up in the
YDL list:

"Otherwise, running headless on a Mac is simple. However, some
machines require sensing the physical presence of a monitor through
the video connector before they will boot. I've never used the 8500
so I don't know if it needs to sense or not. But on those machines
which require it, you can wire up a dummy DB-15 connector (you only
have to connect 2 pins together) and plug it in instead of a monitor.
ADB mouse and keyboard are completely optional."

The old-world Mac servers allowed you to redirect input/output to tty
serial via OpenBoot; I don't know if the desktops have this ability or
not.  I am fairly certain that the modern desktops do not as this is
a feature touted on the server line.
