HP 3000, APL\3000, the HP 2641A APL Display Station, and stuff.

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).
