We have had an AP on one of our 20's and it was total headache time. We
seem to have had a prototype interface which was evidently designed by
someone with no access to DEC's documentation of their memories, it
did not work correctly at all. FPS was at least helpful about fixing
it, but it took a LONG time. 

On the Twenty, also, you dont gain that much performance without VERY
careful coding of programs to run in the AP (their fortran wasn't 
nearly good enuf at reducing loading/unloading programs and data
from the AP).

On the other hand, one of the people here has an AP-120 on an 11 and
he seems pretty satisfied.
