Just synthesized a 512kB FLASH cart with a smaller cpld on it.  8 IO 
pins left...

But, egad, what a nasty IO integration on that 38910.  multiplexed 
address/data bus.  That takes at least 10 pins.  Sigh.  I might be able 
to free 2 more up, if I ditch the LED and the second switch.

Is there a Coco hookup diagram for that IC somewhere, or some 8-bitter 
schematic?
