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).
