I believe 11/20 UNIX also needs the EAE.
Some applications might have used it (the story about the KS11 bug with the
KW11-A confirms they did use it on that machine), but I found no trace of use
of it in a quick scan of the entire Version 1 source (the one which is
extant).
Also, the first file in the OS source:
https://www.tuhs.org/cgi-bin/utree.pl?file=V1/u0.s
lists the addresses of all device registers, and the KE11-A isn't there.
If the KE11 is needed to run some application on the -11/04, there are
KE11-B's (program compatible, but a single hex card) available, ISTR. For
emulation, something (SIMH?) supports it, since the TV -11 on ITS (now running
in emulation,I'm pretty sure) uses it.
