Abstract
Abstract A keyboard-to-tape data recorder with a magnetic core memory to buffer data in the key-to-tape transfer cycle. The memory is provided with a section for storing working data to be recorded and a section for storing program control data which enables the recorder to automatically execute subroutines such as duplicate, skip, etc. The memory loading cycle operates to inhibit keyboard access to the program memory section during normal data entry cycles but permits program data to be added, deleted or changed via the keyboard upon actuation of a special control switch. The program entry cycle enables single-keystroke entry of program data and insures that program data fields adjacent to those being altered are not disturbed.
