pointers on what tss/8 really needs to run

First off, my apologies to the pdp-8 aficionados on the list. While I used
8's back in the day there's a lot I don't know about them.
I'd like to understand *exactly* what hardware tss/8 needs to run.
My understanding is that it will only run on an 8/I with the following
KT08/I timesharing option
MC8/I memory option
KE8/I multiply divide option
I'm curious because I wrote up a simple pdp-8 verilog description which
runs FOCAL and I think it would be fun to run tss/8 also.
I'd like some pointers to documents which describe the options needed and
details about them.
Certainly all of the IF/DF extended memory is needed, since last time I ran
tss/8 we had 32k. I'm guessing that this is covered in the MC8/I documents.
I'm curious if the KE8/I is the same as the EAE.
And I've never seen a description the KT08, all though I can guess what
it does (traps any 6xxx as well as halt and switch register access at
a minimum, but anything else?)
Also, if there is a better list for this sort of question please let me know.
I've never read alt.pdp8.whoknowswhat but maybe I should.
