I've seriously contemplated making my own matching memory expansion 
module for my VXL/30 A500 cpu accelerator.  Fairly complicated because I 
have to create a DRAM controller.  Thinking FGPA w/ a pre-made memory 
controller core.

Yeah, it's absolutely amazing what prices those things command.  I'd 
love to get a back-up A500 accelerator board.

I've been buying/collecting all types of amiga documentation.  I've been 
trying to really figure how it works --- alot of stuff happening inside 
that computer from 20+ years ago.

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.
