PPX-52 and PPX-59 Newsletters

 

In November 1977 Texas Instruments introduced PPX-59 (Professional Program Exchange TI-59), a service for TI-59 users in the U.S., Canada and Mexico to gather, compile and redistribute programs for the calculator, by merging it with the previous PPX-52 newsletter for SR-52 users. Hundreds of TI-58, TI-58C, and TI-59 programs were published before the bi-monthly newsletter was discontinued in 1982 and some of them were bundled in Program Pakettes.

The Professional Program Exchange PPX-59 is featured in the Texas Instruments Incorporated bulletin PPX-59 dated 1979.
