The Giddings & Lewis Data Interface Board 503-15596-02 serves as the communication hub between the executive control processor and CRT display subsystem in compatible CNC systems from the late 1980s era. This 5 VDC module features populated ROM/RAM sockets, NEC memory devices, and logic IC components including MM74HC and SN74HC540N buffers. Originally silkscreened as an Executive Control Board (501-04301-02, Revision 2, June 1988), the unit was professionally removed and documented in September 2016. Ideal for restoration projects or as a spare component in legacy Giddings & Lewis CNC platforms. Verify compatibility with OEM specifications before installation. Offered as-removed; untested condition.
