Westinghouse P-50 Programming Documentation

New programming documentation for the Westinghouse Prodac-50 (P-50) computer

By Dave McGuire

These are new (2026) documents related to programming the Westinghouse P-50 process control computer. The Instruction Repertoire document is a re-typeset rendition of the original manual from Westinghouse, and the Quick Reference Card is a new document.

The reverse side of the Quick Reference Card describes the input format for our p50asm cross-assembler.
