[Coco] 7 chip 6809 computer

[Kip Koon]

Hi Mathieu,

This design has a 7.3728MHZ crystal which the 6809/6309 processor divides by for to arrive at an internal clock frequency of 1.8432MHZ so I would suggest to use the Motorola MC68B09P or the HD63(B/C)09P chips.  Note: unlike the Color Computer, this design uses the "P" version (as in no 'E') of the 6x09, NOT the "EP".  “P” means the plastic case style is used which seems to be the most readily available version from UTSource or HKInventory.  For complete details, please see my wiki page for details.

I would be interested depending of the cost and also is it for the

6809 or the fpga based one?
