The Tektronix M033  (P/N 155-0004-01) is a decoder monolithic integrated circuit for the readout system in the 576 Curve Tracer, designed by Mike Metcalf. It is packaged in a 16-pin DIP.

Description from data sheet

The 576 Readout System is comprised of four fiberoptic readout modules. Three of these modules are each driven by an M38 and M39 (155-0007-01 and 155-0008-01).

The fourth module displays the ratio of vertical current/division to base step/division. This Beta/division readout is driven by the M33, M34, and M35 (155-0004-01, 155-0005-00, and 155-0006-00).

The integrated circuits are programmed from switch closures or external inputs and perform the required logic function to drive the lamps in the readout.
