This disclosure relates to electronically controlled sewing machines and in particular to the combination of such a machine with a re-programmable static memory with which an operator can program in input data representative of stitch position coordinates for selected patterns, which input data will be encoded into digital form, stored and decoded into input signals for initiating operation of the sewing machine stitch position actuating means to produce patterns corresponding to the operator selected pattern. The re-programmable memory can be located remote from the machine or can be built in as an integral part of the structure of the machine itself. The machine may also contain a static read-only-memory (ROM) having fixed patterns for operation of the machine with or without a re-programmable memory and includes switching means for disconnecting the read-only-memory when the reprogrammable memory is connected to the machine. More specifically the invention provides for a programmer by which the operator can physically draw a pattern design of the operator's own choosing and the programmer will generate input data for use by the machine for reproducing the drawn pattern design.
