The current version is called MPE/iX because it includes a hierarchical file system and supports the UNIX function calls (MPE is now POSIX compliant). Programmers are now busy porting UNIX and Internet tools to MPE, as well as entire UNIX application packages.
There is a list server for MPE called the HP 3000-L (all machines that run MPE are HP 3000 systems, and vice versa). A list server is an automatic mailing list of Internet e-mail users which allows people to post messages and reply to those from other members of the list. The HP 3000-L maintains an HP 3000 FAQ. An FAQ is a document of Frequently Asked Questions, and their answers.
