The PDP-8/A was DEC's last non-microprocessor PDP-8. The CPU was a single hex board, which plugged into an OMNIBUS backplane.

There were a number of options available for use with the -8/A, including:

  • DKC8-AA - front panel control, real-time clock, asynchronous serial line interface, etc
  • KM8-A Extended Option - main memory extension and time-sharing control, etc
  • FPP8/A Floating Point Processor - two hex boards, it is not part of the CPU, but uses DMA for its instuctions and data

The -8/A could use either an Operator's Panel, or a Programmer's Panel (similar to the KY11-LB); the latter required the DKC8-AA.

The -8/A came either as a kit of boards, or as a complete system including a chassis, power supply and backplane; in the latter form, there was a list of different configurations.
