Giddings & Lewis Processor Module 501-03865-01 (secondary assembly 502-03061-01) represents a legacy CNC control component engineered for MPX series machine systems. This multi-layer green PCB incorporates industrial-grade TTL logic architecture with integrated clock generation (8284), bus control (8288), and dual serial communications capabilities via MC2661/MC68661 controllers. The card-edge connector design facilitates standard rack-mount integration, while onboard line drivers (AM26LS30/AM26LS32) and a precision 10 MHz crystal oscillator ensure reliable signal integrity in demanding manufacturing environments. Silkscreened test points and jumper-selectable termination options support field diagnostics and configuration flexibility. Ideal for CNC equipment restoration, maintenance, or parts inventory. Sold as-is surplus without functional verification.
