interesting.

TWGS:
1)high speed CPU
2)high speed oscillator
3)GALS (what are these connected to?)
4)ROM - is this code for the FPGA only? or does it contain 65816 code
as well?
5)RAM for cache - connected directly to the CPU?
6)FPGA - XC2064 RAM-based part,  loaded from EPROM.
---what function does the FPGA provide?  what does it
   connect to on the board?

I would like to know more about the board and how it runs...  Seems to
be
a neat combination of systems working together.
