An IMP interface is a device used to attach hosts to systems which used the special 1822 communication interface (defined in BBN Report No. 1822); these included initially the IMPs of the ARPANET, and later the PRUs of the Packet Radio Network‎.

List of some of the most popular interfaces:

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
DEC CSS IMP11-A, 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 for NCP
ABSI, used by 6180 Multics or NCP and IP
Alto interface, used on the Maxc2 front end to connect to the ARPANET for NCP, on PUP gateways to talk to PRUs, and apparently eventually on the Alto ARPANET IP gateway

but there were many others (many being 'one-off' local creations).

This article is not as complete coverage of the topic as it could be. You can help by expanding it.
