Plotkeyboard

This document describes the PLTKBD (Plotkeyboard) program for the LINC-8 system. The program allows users to plot Teletype keyboard characters onto a CALCOMP 365 Plotter. It includes specific controls: LSW for character size, SNSO for 90-degree rotation, and ALT MODE keys for special functions like head stamps (used in electroencephalography) and positioning. The program is built to work with the PROGOFOP instructions and is protected against illegal ALT MODE inputs.
