   I am considering building some hardware extensions myself, but
   i can't find any info on how to do it. All i could find out was
   that cards must contain some sort of boot rom, which holds a card
   identification and a piece of boot code for the processor to
   execute at system reset. 

   Could somebody help me out, or give me some refs to articles,
   technotes (if any) or books about the subject? 

The extension cards in MacII serisare called NuBus-cards. Addison Wesley
has published an Apple manual "Making cards and drivers for SE and
MacII", that discusses these topics. I'm not guite sure wether there is
yet a book for the newer modells also (probably is).

Also there are card manufacturers that make NuBus prototyping cards,
that have most of the essential NuBus-card functionality built in (like
the boot rom and drivers), and spare space to build your own circuits
on. Unfortunately I don't have any addersses of such companies (maybe
someone on the net does). Theese may get you started.

   Thanks in advance,
   Rudi Bloks
