Yeah, that's the one, all right. My dad remembered it
when I mentioned the name. Really is a shame they
don't make 'em anymore. There are a few similar
devices designed for aircraft and boating applications,
but they all use a NMEA GPS input to monitor vehicle
speed and (of course) don't have a cruise control function.
I've found a device used for racing engine telemetry but
that's certainly overkill for my needs. I may have to build
one myself...
