Having had several opportunities to photograph the data on the screen of my TRS-80,1 decided to come up with a way to set the exposure more accurately.

TRASHMAN is a machine language utility for the TRS-80 Models I and III. It was written by Glenn Tesler, the author of FASTER, and can reduce BASIC'S string compression time by 95 (see table below).

Eventually, all available memory gets used up and BASIC has to push the strings together to free up some space, This takes time. Lots of time. The computer...
