A Zorro2 memory board is a "Slave" board and I answered this question in advance on the Amibay thread. I don't know about the Thylacine but Deneb in Zorro2 DMA mode certainly qualifies for this mod. 
Thanks! I wasn't familiar with that term "slave" board. :crazy:
Wondered how long it would take before @magnetic would chime in here.
Obviously they're your tips (and we thank you for them!), but your limiting yourself a bit IMHO. Amibay might reach only, what... 10% of the Amiga audience? At least if I google your tips they come up with links pointing to there, so it's not like the stuff is totally impossible to find. I'd still throw a copy up on Aminet for good measure, but again, your call. Thanks for doing all this hardware hacking for us! :pint:
