I learned BASIC in an HP3000 series II, I think, back in '78.
It had slow graphics terminals; they were very cool.
I did not learn anything about administration, though.

MPE=multiprogamming executive, i.e., a basic timesharing
system in its beginnings. I have the Jan. '73 Hewlett-Packard
Journal where it is introduced.

Contents:

1) An Economical Full-Scale Multipurpose Computer System.
   Abstract: This is the first 16-bit computer with a hardware stack
   architecture and virtual memory. It handles time-sharing, batch-
   processing, and real-time operations in several languages
   concurrently

2) Central Bus Links Modular HP3000 Hardware.
   Abstract: Sharing the bus can be one or more cpu's. I/O processors,
   memory modules, high-speed I/O channels, and special devices.
   The microprogrammed cpu's have a procedure-oriented stack architecture.

3) Software for a Multilingual Computer.
   Abstract: SPL is a high-level language that's as efficient as other
   system's assembly-language code. Other 3000 languages are FORTRAN,
   BASIC, and COBOL.

4) Single Operating System Serves all HP Users.
   Abstract: The Multiprogramming Executive operating system takes care
   of command interpretation*, file management, memory management,
   scheduling and dispatching, and input/output management for
   time-sharing, batch and real-time users.

[*] I'm sure it wasn't a preferred OS at AT&T.
