Bill Jonesi has directed us to the "Navichron" clock (cheaper than a Heuer
Sebring, anyway!). I wonder if any Halda geeks on this list know anything
about a strange black box that Rusty Link installed in my Saab 96 over
thirty years ago (along with his Halda Twinmaster): this box had two cable
connections, one coming in from the dead-wheel drive and the other going out
to the Twinmaster.

Inside the box was something called a ball-disc integrator, and the front of
the box had a vernier dial. Its purpose was to adjust the relationship of
the incoming and outgoing cable speeds, giving you infinite adjustment of
Halda. No swapping of X and Y gears! Pinpoint accuracy!

Link, of course, does not remember exactly where it came from, and I've
never encountered another like it. Anybody ever see one of these or know
anything about it?
