I have a Mac Plus w/ 2.5 Mb, a LaCie 110 Mb hard disk, and no nonstandard
INITs, CDEVs, etc., in my system folder except for TMON.

Since my hard disk has no visible read/write indicator (it's closed up
inside the case), the LaCie driver blinks a 3-pixel blob just outside the
upper-left-hand corner of the display to indicate disk access.

However, when the computer is just "sitting around," no disk access, no
mouse movement, etc., a single pixel will flicker (blink) quickly every
few seconds, at irregular intervals.  Most of the time I've spent on the
machine lately has been while running THINK C 4.0, and I'm not sure offhand
whether I've observed this running another application.

So, umm ... what is it?
