IT WORKS!!!
With a bit of effort I can now receive data from the UART on my keyboard controller, into the CPLD and read it form BASIC on my 6502 laptop revision b (slim version).
I've set the Keyboard controller to output characters from $20 to $7F, here you can see them being shown.
There is also a "new data received" status register too!

@PaulaMaddox nice!, what does the serial RX on the 6502 side?
Here is my ROM based FSM that does keyboard!
