Phil (and all else),

I haven't tried to bring up 3.6 yet, but I have brought up 3.5.  The
D model works great iiiiiiffffffff..... you also use the -s switch
(or use -mds if you compile with lc).  This tells the compiler that
you don't want him to "normalize" all pointers and all results of
pointer arithmetic.  A normalized pointer is one in which the offset
is always in the range 0x0 - 0xF and the segment is pointing at the
appropriate paragraph.  For example:

	0900:1237	is converted to		0A23:0007

The advantages include: comparisons between arbitrary pointers are
meaningful and addressing (using pointers) > 64k of data.  Disadvantage
is significant CPU time consumed normalizing pointers.

This will cure your slowness problem.  D model is probably the best
choice for Microemacs.  S model doesn't have enough data space.  Ditto
for P model.  L model is unnecessary as the code space for Microemacs
doesn't exceed 64k.

As for your other problems.  I can't help you (yet).  Please let me
know what you learn about them.

Regards,
Larry
