You need to get a copy of the "M68000 User's Manual"
(ISBN 0-13-567074-8) for the 68000 signal timing.

A 68000 will wait forever for the DTACK signal.  (Since this wouldn't
be a very social thing to do on the Amiga, a DTACK signal is automatically
generated for the Zorro-II boards.  One has to do extra work to
delay the automatically generated signal.)
