[Coco] 6809 FPGA Success

[Bill Nobel]

I am at 10Mhz as of that pic.  I really need to get a PC booted up with Quartus to try this again, I have a couple.

Most of the time when I program the Nano, I get a flaky VGA, it flashes the image in and out.  When i get the image I can see what I typed, but very unstable display, until I get a good programming that boots properly.

I have been also playing with internal ram going bigger, tried 64k, too big for the Nano. 8k compiles, no complete programming yet.
