I assume the PAL chip is required for this to function with a 65c816 installed. Did it require any software to work? I can't seem to find any info besides the manuals which don't go I to details about how this works. The only other thing I found was a picture of the EX version (for the iie) that has a W65C816P-4 and a PAL16L8A-2CN. Is that the same 816 that the CX uses? So many questions...
