I think I remember that one. I had a ROM-Listing in book form once, but 
it disappeared. The main problem with it was that all addresses were 
decimal while the monitor on the system itself of course used hex.

Also, the one I had was based on KERNAL -04 while -05 was the one you 
wanted to use.

I remember there being a rather simple test to find out if you had a -05 
ROM, some BASIC command would crash if you didn't. Anyone remember 
details? The differences between -04 and -05 are rather small.
