Does anyone have any thoughts on LAT's using ethernet versus use of
a PACX?  I've heard that LAT's have a high cycle cost.

What is the definition of "cycle cost"? If you mean "unit cost per connection",
then yes, you are correct. 

If you mean COMPUTER (i.e., HOST) cycles, I'm not real sure. Intuitively, I
would THINK that the ETHERNET approach would be less overhead, particularly
if DEC starts taking full advantage of the PDP-11 in the server to do 
"host" things, like echoing characters. 

Anybody else have speculations?
