According to Turbo Technix (Vol 1 #2), the add-ins are .EXE or .COM
files containing interface routines "...linked from the library
distributed with the Quattro Add-in Toolkit.  The extension is changed
to .QAI from .EXE or .COM so that a user cannot accidentally execute
an add-in from DOS."  It goes on to say that you may have a max of 
8 extensions (which may be a mix of either @ functions or add-ins).
The add-ins may be explicitly invoked by the user or triggered by
significant events on the spreadsheed (e.g. moving a block of cells).

A note mentions that there will be (was) a Developer Conference in
Santa Cruz, California Jan 20-23 and that a copy of the toolkit,
lodging and all meals were covered by a $395 fee -- so I would
guess (but only a guess) that it is in the range of the other
toolkits/boxes.
