Eliminates the strobe flicker and fatigue from TRSs

Now you can upgrade your monitor with the new medium persistence green or amber phosphor tube. State-of-the-art systems such as IBM and Apple III do not use the less costly P4 B& W display tube because it is actually intended for TV viewing and its rapid strobes (60 times per second) cause irritating eye fatigue. No amount of green plastic will solve this problem. But the new Soft*View CRT display tube from Langley-St. Clair will. *GN42 Green Phosphor 79.95 *GN42G Green Phosphor w Anti-Glare...

This causes some extra steps if you write a BASIC program to, say, address a letter you intend to write with Scripsit....
