I'm sure the Subway works with Kickstart 1.1 with Anaiis. But other Clockport expansions, being designed for the A1200 primarily, may require 3.0 or 3.1 ROMs depending on the software controlling them, but I haven't got any others to test. In any case, with a simple Kickstart ROM switcher and both 1.3 and 3.1 ROMs in the A500 you should definitely be able to get the most out of what your A500 can do anyway.
