PRO-WAM (also known as PRO-NTO) is a collection of pop-up tools for LS‑DOS/TRSDOS 6 on the TRS‑80 Model 4. It was written by Karl Hessinger and Roy Soltoff and cost $59.95 when it was introduced in December 1984.
PRO-WAM was one of the few programs to require a Model 4 expanded to a full 128K of memory. In my opinion, it was one of the best uses of the extra memory and one of my favorite Model 4 utilities.
