[Coco] 6 Chip 6809 Computer PCB Price

[Bill Nobel]

Oops, missed that part, but none the less they will work.  I also have some 6821’s coming as well and am going to modify the circuit a bit to see if I can get at least Drivewire on it.  I am also looking into a MMU circuit that may bring more RAM to the unit.
