The PDP-8/E was an improved model in the PDP-8 line, and introduced the OMNIBUS for interfacing to device controllers.
The PDP-8/F was a cost-reduced version of the -8/E with the same CPU and main memory, but only a single OMNIBUS backplane. The PDP-8/M is the OEM version of the PDP-8/F.
It could perform an addition to the accumulator in 2.6 microseconds, and a 12 by 12 bit multiplication with 24 bit result in 40 microseconds with the math extension hardware.
