6809 sbc

Update: Now with 40pin edge connector for use with expansion cards and backplane from the CZ boards.

6809 based SBC Most of the design from Grant searle original design.

This board supports both Microsoft basic (simelar version to Dragon 32, without graphics) and BBC Basic v2 (again without graphics)

I have Added  jumpers to allow 512k ROM giving access to four pages of ROM with jumpers, also re-connected the RTS line to aid with hardware connection to a PC. And added jumpers to change the Serial flow control Signals.

The circuit layout was created by me with improved silk screen markings to help make sure things like the FTDI are connected the right way!
