[Coco] GIME Chip Registers and the ultimate repack

To test it will sort of, kind of cluged into the 68 pin socket area. Most 
likely the FPGA will sit on a 100 pin PGA board and that will have 
an adapter of some creation to the Coco3 motherboard. Eventually I 
may do a complete new mother board PCB and redo the entire 
package. In any event there most likely will be no backward socket 
compatibility. 

I really do not want to deal with an SDRAM controller, so what I am 
planning on is to put the FPGA, clock chip, crystal, and 2 megs of 
SRAM on a daughter card. Then remove the 512K ram expansion 
board and GIME chip and go from there.  If all things go well, 
maybe by Thanksgiving it may work.
