Has anyone read the newest issue of ST-log?  In an article
concerning the X-former II (8-bit Atari Emulator) the author states
that the TOS uses non-optimizing 68000 codes "everywhere".  This
must be one reason for GEM's slowness.  Perhaps one approach
currently for improving the ST is to write faster, more optimizing
routines for components of GEM/TOS (such as AES, VDI, and Line-A
routines) and interface these routines to the OS so that programs
which call these TOS routines often can use our faster routines
instead, like what the program "Turbo ST" is
trying to do.   This way current programs can remain compitable, and
their performance can be improved.  This approach also encourages 
the writing of well-behaved program since they can call our faster
routines instead of finding someway to cheat in order to get the
performance they need.  This method can also serve as a starting
point of writing a more complete TOS substitution.  Any comments?
