A2091/GVP Guru ROM adapter PCB
« on: November 27, 2004, 07:47:12 AM »
Can someone trace out the Guru ROM's little adapter PCB?

I noticed that Ralph Babel has made the images available on his website.

Unfortunatly this little PCB has a GAL chip on it... without the equation you wont be able to duplicate it.

I've been wondering if you could make a board like the kickram board on Aminet for the 500/2000, but for the 2091 instead. I havven't found a set of the schematics for the 2091 anywhere though...

Ah damn. I guess I'll need to hunt down the real deal. It can't be very difficult though, probably just address decoding.
