An IMP interface is a device controller used on a host (i.e. on its bus) to attach them to systems which used the special 1822 communication interface (defined in BBN Report No. 1822); these included initially the IMPs of the ARPANET (hence the name), and later the PRUs of the Packet Radio Network.
Some of the most popular IMP interfaces were:
- BBN IMP-10, used by TENEX
- MIT DM IMP, used by MIT-DM. Made by Bob Metcalfe
- MIT KA IMP, used by MIT-AI, -ML, and -MC
- DEC AN-10, for the PDP-10 I/O Bus
- DEC CSS IMP11-A, UNIBUS
- DEC CSS IMP11-B, UNIBUS
- ANTS/ISI IMP Interface, UNIBUS
- Stanford 1822 Interface, UNIBUS (via a DR11-C) and QBUS (via a DRV11)
- ACC LH-DH/11, UNIBUS
- ACC MLH-DH/LSI11, QBUS
- GIMPSPIF, used by 645 Multics
- ABSI, used by 6180 Multics, for NCP and IP
- Alto-1822 Interface for the Alto, used in a variety of ways
but there were many others (many being 'one-off' local creations).
