[Coco] FPGA 6809

[Bill Nobel]

I have gone over Grants code extensively and I never found a symbol file for Chip select. I see the CS lines defined, but not such as Roger’s define for a symbol file.

I am a noob when it comes to these things and was having trouble marrying the data_in data_out busses together to form a actual bi-directional bus.  I thought I was needing to build a circuit with latches/buffers, and he decides to give me a ~20 line piece of vhdl code that does the whole works based on Chip selects. Woo hoo….
