I never checked this, but maybe it is just the logic to create the proper /CS 
signal for the EPROM, it might be inverted at the 6530 input. At least this 
was always my explanation for the presence of that chip, but I never checked.

Anyway, great that the system now works, whatever failure it had ;)
