[comp.sys.m6809] 1 Meg For CoCo 3

houser@mcnc.org (Kevin Dan Houser) (08/09/88)

        Does anyone have schematics or information on a 1 MEG
 Upgrade for the coco3. I have a 512K board that I installed
in the coco3. BUT I would like to take the 8 extra 256K drams 
I have, coupled with  8 more, and Make an OS9 Compatible upgrade. 
Not just as a ram disk, but as mapped (block switchable memory).

Any thoughts, help, or ideas are appreciated.
