Update to DECUS PDP-8 FOCAL8 BASIC8 PDP-12 Catalog Volume II 197505

This document is the "UPDATE TO DECUS PDP-8, FOCAL8, BASIC8, PDP-12 CATALOG VOLUME II," with its latest update dated May 1975. It serves as a comprehensive catalog of software programs available through the Digital Equipment Computer Users Society (DECUS) for the PDP-8 and PDP-12 computer systems, as well as the FOCAL8 and BASIC8 programming languages.

The catalog organizes programs into various categories such as programming languages, monitors, text editing, debugging, utilities, scientific applications, hardware control, games, plotting, and business applications. Each entry includes a unique DECUS number, program title, and often a detailed description specifying minimum hardware requirements, storage, and source language.

Users can obtain these programs by paying service charges for reproduction, handling, and postage. Programs are available on a variety of media, including paper tape (binary/ASCII), DECtape, LINCtape, and magtape, with varying costs depending on the chosen media and whether the user supplies their own blank tape. Documentation (write-ups) is generally included free with program or library tape orders, but separate requests or bulk orders may incur additional fees. The catalog also lists service charges for complete library tape collections for various PDP systems, including options for updating previously acquired library tapes.
