The Authoritative Website for Timex/Sinclair Computers
Bob Fischer was a middle and high school band director. He used his Timex/Sinclair computers to develop a gradebook program, which he used in the classroom.
He also used Tom Wood’s Pro/File 2068 database extensively, developing new routines and refining the code. He published Extensions, a newsletter about his updates to Pro/File 2068.
