[comp.sys.mac.programmer] Heirarchical Menu Timing again

afoster@ogccse.ogc.edu (Allan Foster) (04/24/89)

Hi All,

Ok I had to deal with the Hier menus in system 6.0 when
the system put the timing in a place not available
in a mac plus, this caused 4.5 sec delays on a 512K
machine with added mem.

The locations that are used are 0x7e and 0x7f ie the
last two locs in the pram.  I walked thru the roms with TMon
and found these addrs.  They now check the ver of the Pram 
and use default vals if it is an old 20 loc Pram chip!
