The FNX6809 is a DIP40 module that is effectively a Cycle Accurate Motorola MC6809 CPU, working @ 3.3V and capable of running @ 6.29MHz on the F256Jr or the F256K.

The FNX6809 also differs from a real Motorola MC6809 CPU in that it has the 65C02 pin-out.

For these reasons, it is not designed (at least for now) to be a direct replacement for an MC6809.

An Adapter is supplied with the FNX6809 module to be enable reflashing the on-board FPGA, if ever needed.
