I started out at System Reference Code list at
Click on C. This went to C5xx. It was suggested that I use the IPL SRC

If I use the IBM search box way up at the top right and searched for
C500E200 I got nothing. Google only returned the posts from this thread
from the archives. (I'll ignore the references to the Spice Girls.)
There is a link in the System Hardware Information at
However that had the same generic information as the IPL SRC finder had.
Why doesn't IBM tell us what the other numbers mean?
