The FP11-B was a FPP used in the PDP-11/45 and PDP-11/70 computers (KB11-A and KB11-B CPU variants, respectively). It uses a clock which is not synchronized to the basic CPU's clock.

The FP11-B included the following boards:

  • M8112 ROM and ROM Control
  • M8113 Exponent and Data Path
  • M8114 Fraction Data Path - High Order
  • M8115 Fraction Data Path - Low Order
