The catalog for the PPX Exchange shows two TI-59 programs associated with road rallying:
988002A Road Rally Navigation by Clyde Durbin of Dallas, Texas
Originally written for the SR-52. Designed for time-speed-distance navigation using only the car's tenths reading odometer, one time-of-day watch (hours-minutes-seconds) and the TI-59. Program features (1) perfect watch time for any odometer mileage; (2) automatic speed change; (3) off-course recourse; (4) pause and gain speed; (5) current and next speed; (6) converts odometer mileage to official and vice versa.
988013E Real Time Road Rally Average Speed Program by William Zenker of Sarasota, Florida
Initial inputs of the desired average speed and the beginning odometer reading will provide the rallyist with a continuous read-out, updated at 15 second intervals of the desired odometer reading in real time. Time keeping accuracy can be easily calibrated for temperature, humidity and individual calculator variations to within +/- 4 seconds per hour. Upon completion of the run, initial entries can be recalled along with the mileage total and the total elapsed time in 15 second increments.
I do not have a copy of either program and copies are not available at Viktor Toth's site.
If the TI guys published road rallying programs the HP guys must have done the same. In those days neither side wanted to be in a position where the other side had a capability that they didn't.
