Also, how many wires are connected to the memory board from the DAT board that contains the 6809 cpu?  If there are two wires labeled D6 & D7, then I would expect you have a 2MB Coco 3!  :)  Just one wire labeled D6 would definitely be a 1MB memory upgrade.  Try running NitrOS-9 on it and let us know what the mfree command displays.  Inquiring minds want to know!  :)
