View source for IMP11-B ARPANET Interface

The '''IMP11-B ARPANET interface''' was a [[network interface]] produced by [[Digital Equipment Corporation|DEC]]'s Computer Special System division for the a [[UNIBUS]], which provided an [[1822 interface]]; the latter could connect to anything that provided a BBN-1822 bit-serial interface, most commonly including [[IMP interface]]s to [[ARPANET]] [[Interface Message Processor|IMP]]s, but also [[Packet Radio Network]] interfaces.

It consists of a pair of [[DEC card form factor|hex]] boards, one a [[KMC11]]; they mount in an adjacent pair of [[Small Peripheral Controller|SPC]] slots. Level converters allow use as either a Local Host or Distant Host interface.
