Designing Amiga Expansion Hardware

[JimS]

Look at this site... www.pad2pad.com. Once you do the design, you can use their software to layout the board and do the traces. Then you can have them build it for you. Sounds cool, someone just pointed me there yesterday. I've always wanted to try doing a PCI buss adapter to hang off the side of the GVP processor card in my 2000. Just for fun :-) Or maybe a recreation of the Zorro to ISA adaptor from way back..

A couple years ago I looked around the net for some info on interfacing the 680x0 to the PCI bus. I did find an application note for a circut that used 2 chips. One was the companiy's product, the other a generic PLD with some glue logic defined into it. Even had the equations for the PLD in the note. My notion was to hang this off the back of the GVP card in my 2000.
Doing the ISA bus would be easier. There was a card on the market that did it... I think they just mapped the ISA expansion space into part of the Zorro II memory space.
