BA nuts ans bolts are still commonly used by model engineers over here,
amazingly. And they do turn up on electrical stuff, when I bought some
barrier strips recently, I found I could get such thins with M3.5,
6-32UNC or 4BA terminal screws.
Anyway, BS fasteners are not common in classic computer stuff, but you
will find them in old British stuff. Creeds being the most common place,
but otehr things too. I suspect old GPO modems, for example, use them
(the telephones certainly do).
