A route planner for the TRS-80, written by Linden Software for haulage firms.
Provenance
Bought as part of a box of disks at an estate sale and donated anonymously. The tape had stretched near its start; the first blocks were repaired by hand from the sampled signal. All files were recovered; 29 damaged sectors were rebuilt from redundant data.
