I misspoke: A16/D16 is available.

There is only one slot, but I have seen a new box for the TT030 with
many VME slots -- this was from another company, in Germany, but it
proves it can be done.  I think the internal slot is half-Eurocard, 3U.
If I'm abusing the VME terminology, I apologize: I don't really grasp
it myself.  The cards I've seen that fit are about 6.5" by 4.5".

Host memory is not accessible through the VME bus -- that is, a VME
card in the TT030 cannot be a bus master.  My standard answer on this
subject is as follows: "It is not unreasonable to suppose that there
may be a future machine from Atari with a full-size, full-feature,
multi-slot VMEbus interface."
