MIT TECO, the implementation language for the original EMACS, executed
the code to move the buffer gap in the ACs, for speed. At one point
we ran some fairly hairy custom TECO programs to sort and merge the
MIT and NIC host tables, and it was not uncommon to a TECO that was
executing that code madly spinning away in the ACs. Particularly when
the code was running on a KS-10, where the ACs weren't any faster than
the rest of memory.
TECO's sorting command ("^P") may have also run in the ACs.
