I worked with them in some printes and other devices, HP used one in a
daisy wheel printer (9872a AFIK), at a time whem Diablo Queme and
Company where using a steel cable. You could replace the Mini Pitch in
the HP in less than 1/2 the time it took to replace the cable in the
others. This also applied to replacing motors.
