I've just uploaded the FOXBORO User's Guide from 1973 which has some details on how their part numbers correspond to other 74xx chip vendors to:

PREFACE
FOXBORO Integrated Circuits Users Guide
Ths book (document 73002BZ) is intended as an aid to maintenance personnel servicing process management and control equipment such as FOX 2 Systems.
It contains information necessary to trace signals through or replace integrated circuits (ICs). ICs described herein are used in standard system components manufactured by the Foxboro Company. ICs in standard system components, such as computers, drums, CRT consoles, etc. that are part of the Foxboro product line, but not manufactured by The Foxboro Company, are not included.
Foxboro part numbers and equivalent IC manufacturer's part numbers are identified in Table 1. This table can be used as a parts substitution list in the replacement of integrated circuits.
All integrated circuits described in this standard book might not be in any given system, and any ICs for custom modules designed specifically for your system are not covered in this standard book.
IC information is presented in Foxboro part number sequence, as indicated in the table of contents. Pages are not numbered, so information on an IC is located relative to the alpha-numeric part number sequence.
This guide cross-references 74-series TTL logic chips between the following vendors:
FOXBORO - Texas Instruments - National Semiconductor - Sprague - Motorola - Fairchild - Digital Equipment Corporation - Signetics
NOTE
This book was supplied with the FOXBORO FOX 2 System, a rebadged DEC PDP-11/15 minicomputer.
