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:
The term "Slave" is used by Dave Haynie in various Zorro bus specification docs he wrote. Any type of Zorro2 or Zorro3 card which lacks the ability to master the bus is a slave. The DMA boards are described as bus "Masters".
However, a DMA board must first arbitrate the bus before it can master the bus. The Buster chip acts as a sub-arbiter between the Zorro slots and the CPU. This hack speeds up the sub-abitration process.
P.S. Please don't reply to magnetic's post. His issues with Amibay are completely OT from this topic and he's already caused several threads to be closed. I don't post these links as "Troll Bait" but your on-topic comments and questions are certainly welcome.
