ABSTRACT:
A programmer unit which is connected to the keyboard of a machine is capable of storing, as a program, the sequential occurance of key closures, and of supplying simulated key closures through the keyboard to the machine in the order in which such key closures were initially generated and stored. The programmer enters that key closure information into a storage register. The programmer includes a main control circuit which is responsive to various inputs supplied thereto for also entering control information into the storage register. A register control circuit is responsive to instructions from the main control circuit for entering this information into the correct position within the storage register. When the stored program is accessed, the register control circuit is responsive to instructions from the main control circuit for transmitting key closure information from the storage register in the order in which such information was originally stored. The accessed information is converted into signals which simulate key closures and such signals are connected through the matrix keyboard to the machine being controlled. A method of storing a program in such a programmer unit includes entering a pair of control words into adjacent storage locations and thereafter shifting one of the control words one storage location for each word of key closure information and filling the vacated storage locations with words of key closure information. Such key closure information may correspond to the closure of either a function key or a programmer control key. During accessing of the stored program, a third control word is initially entered and one of the pair of control words previously entered will be at a storage location which will always be adjacent the next word of key closure information which is to be accessed.
