Re: General 6809 card for 6502 machines

I used this one: (in fact the first I found)

http://www.zimmers.net/anonftp/pub/cbm/schematics/computers/pet/SuperPET/324037-1.gif

I find strange to see a 6809 with using a 1Mhz clock...
I would love to have one to check on the real board...
I've never found this board at a decent price on ebay...

that's why I was thinking to rebuild one
I'm actually on a reproduction of the 8032 64k extension
