[Coco] Dual UART with FIFO Card for the CoCo

I honed some skills inmanual routing having to route RF signals on a very small board and at 
900 MHz. Trust me there is no autorouter that can handle that kind of work. All the RF 
frontends that I worked with ran off ov 0.95 VDC. At 900 MHz long runners are in the range of 
15 to 20 millimeters. 

I routed a lot of digital boards in matter of minutes with Cadence Tools that included Spectra. 
Darn expensive tools but very godd ones.
