Yes, it has everything to do with the mouse port. . . Unless. . .

Well:

A) When you get a mouse card for a //, it supplies it's own 60 Hz
interrupts, which it uses when it's "turned on", internally.  You can,
however, get it to send the interrupts to the CPU. . .  E-mail me for
details.

B) You can also get something like this by nabbing a line off the
motherboard and going somewhere with it.  I'm really being vague for a
reason. . . It's not trivial.  You may think you can just grab the refresh
signal and plop it down on PB2 or somesuch. . . But I'm not sure you can do
that.  If anyone is interested, I'll check it out, and tell you how to do it
right.
