I've been buying/collecting all types of amiga documentation. ?I've been

I've made an external usb amiga floppy drive controller. Attaches to USB on
PC and a regular 34-pin floppy drive -- creates .ADFs for archiving,
emulators, etc. ?Fun project. It's prototyped and not easily/cost
effectively reproducible. ?But lots of fun.
I'd love to have a 500 with an accelerator. Alas, limited money means
higher priorities first.
From what I understand (I'm a software guy, not
hardware), the amigas
were really easy to create accelerators for. There's a
pin on the
zorro 2 slot, iirc, that takes over the cpu. It's like a switch for
the 68000. I wish I knew more about hardware.
I've seen discussions on amiga.org about recreating accelerators for
the 1200, especially the phase 5 68060/powerpc board. The consensus
was that this board was so complicated and well-engineered that it
would way to expensive to recreate. I can't imagine why a 2000 or 500
accelerator would be so hard to make though.
