I will be adding this mod to my coco, plus probably another 128k on top of that. My coco has been modified to include Address, Data, Read-Write, E, Q buffers for the 6809. So the bus is strong enough to handle the additional load. The SAM can handle 4 banks of ram according to the specification sheet. I did not get that issue of the magazine, but received the schematic for the modification. I would like the program that accompanied the schematic. 1. Has anyone added this mod ? 2. If you have done this, do you like it ? 3. Have you used this extra memory for a ram-disk, etc. ? paulba @ tekgvs
