OK--here's one for the real IIGS gurus our there.

On ROM 01, the pointer to the Memory Manager's list of active blocks is at
$E1/1600, the pointer to the list of purged blocks is at $E1/1604, and the
pointer to the list of free blocks is at $E1/1608.

Are these three pointers still in the same place in ROM 3?  If not, where
have they moved to?

I need this information because I want to write a program that walks the
handle list, identifying certain kinds of blocks on the basis of UserID,
attributes, and size.  To do so, I must of course find the start of the
list, and I'd like to do so in a way that works on ROM 3 as well as ROM 01.

(I realize I could call FindHandle($000000), but that only works for the
"used" list--not for the "purged" list or the "free" list.)
