Having collected half a book shelf full of GAL devices data books I am of the 
opinion that there is some global conspiracy not to provide enough data for 
anybody to be able to do this for them selves.  I have even tried faxing Lattice 
semiconductors, they completely ignored me too!

I did some work on reverse engineering the serial data protocol between my 
LogicLab GAL programmer and the PC with a view to writing a RISC OS 
driver, (the programmer wants CONTIGUOUS bytes at 9600 baud, the PC 
emulator is not up to this!).

I kind of lost interest in the project since I don't do GALS that often and the PC 
connects to Arc via Econet anyway.  I am going to try the 486 PC card from 
AtomWide as neither my GAL programmer or my ROM programmer will work 
with the PC Emulator.
