Hello, today I've received a 3B/1A "Attached Processor Interface" or
"API" (as I will refer to it in this email, note API will not mean Application
Programming Interface in my contributions to this discussion) pamphlet, published by WECo
in November 1981, concerning installation and maintenance of the API. From the
introductory page:
This lesson is a self-paced package that can be
administered individually or in a classroom environment. There is a helpful glossary in
the back of this booklet that you may use while going through the material.
At the conclusion of this lesson, the installer will be able to:
- State the purpose of the API as it applies to the 3B Processor.
- Identify the different types of circuit packs used in the API.
- List the number of API diagnostic phases.
- Name the API circuit pack that interfaces the Dual Serial Channel in the 3B Processor.
Among the many pages (which I'll be doing a formal scan on in the future) are some
references to BSPs and schematic drawings relevant to this information, I wanted to get
that information out in the email archive now so the bibliographic references are
preserved somewhere:

There are then references to a few "Handbooks":
HB 309 - 3B Proc
HB 263(A) - API ITS (Mainly mentions tests and diagnostic stuff)
HB 264(A) - API Generic (Not sure what ITS and Generic distinguish here)
Finally, a bit of fun. Towards the back of the pamphlet is a small crossword puzzle
concerning the API: https://i.imgur.com/0pLcK9p.jpg
Answers to come when I do a scan of this. If anyone has any particular information they
want me to try and find in it sooner rather than later just let me know, it's 88
pages but small form.
