Hewlett-Packard film recorders and plotters.
Hewlett-Packard Interface Bus (HP-IB) A channel consisting of an HP-IB cable
connected to an HP-IB interface card that is connected to the system's backplane. It
performs protocol translation between the CPU and HP-IB. For the 900 Series HP 3000
system up to six devices can be connected to a single HP-IB channel. Disk drives, tape
drives, and system printers are connected via an HP-IB which is HP’s implementation of
the IEEE standard 488-1975 interface.

directory when none is specified at logon time.
home group The group to which a user is automatically logged on to if no other group is
specified with the HELLO or JOB command. If no home group is assigned, the user must
always specify a group when logging on. The account manager assigns the home group
when a user's name is first defined.

installation. 2) In a network, the computer that primarily provides services such as
computation, database access, or special programs or programming languages, to other

MPE/iX it is not necessary to specify RUN FCOPY.PUB.SYS to invoke and run the FCOPY
program. It is only necessary to enter FCOPY.
