It's actually sorta annoying when you discover how much HP copied from
IBM in those days. The first giveaway is that APL\3000 has a backslash
in the product name when everything else was a forward slash as in
BASIC/3000, FORTRAN/3000, and even RPG/3000 (which was another
functional copy of an IBM product), and of course this is likely
because of APL\360. Most people, even inside HP, started calling it
APL/3000 almost immediately though.

APL\3000 is supposed to be a functional superset of IBM APL SV
(APL\360 with Shared Variables etc.) and HP advertised it as such.

The other one that took me a while to notice is the HP 2641A APL
Display Station that came out after the 2640 and 2645. That
out-of-order numbering was kind of interesting until you discover that
the IBM Selectric-based printing terminal with the APL type ball was
the IBM 2741 (sigh).
