The FP11-C was a FPP used in the PDP-11/45 and PDP-11/70 computers (KB11-D and KB11-C CPU variants, respectively). It uses a clock which is synchronized to the basic CPU's clock.

The FP11-C included the following boards:

  • M8128 ROM and ROM Control
  • M8129 Exponent and Data Path
  • M8126 Fraction Data Path - High Order
  • M8127 Fraction Data Path - Low Order
