Worked great for Reuters who used 8's for routing their news
teletypes... but they wanted something faster.
The word I heard is they were the ones that used the PDP8 emulating
11/60's. I guess normal PDP 11 io devices were used along
with the emulation of the 8's trapping to the normal 11 instruction
set to do the i/o.
Perhaps disk container files were used for the 8 files and
DZ or DH11 lines were set up to emulate the KL8's...
