    I know that PDP-8 was also used as FE for some PDP-10s. That might have
    been early KL-10s as well. But I'm fairly sure that there was PDP-11 FEs
    with DECtape as well. (But I'll admit it was quite a few years since I
    gazed at a KL-10 with DECtapes now. I wonder if those machines I know of
    are still around...)

    Well there's 'FE' and 'FE'. The Real Front End, which every KL had,
    aka the console processor, was an 11/40 running modified RSX. KA and
    KI machines didn't have a Real Front End, they had a Real Front Panel
    - much more fun! KS had an inbuilt console, based on an Intel 8080 I
    believe. No pdp-8 was ever used as a Real Front End on a -10.

    Having said all the above, I believe some -10 equipment, which could
    be described as 'front-end' (e.g. comms processors) *did* use pdp-8s
    as their CPUs. Can't recall the model numbers offhand.

    As posted earlier, here's one KL with DECtapes that is still (partly)
    around: http://www.corestore.org/dec10.htm (you can also see the -11
    FE).
