I'm about to commit myself (and my money) to the purchase of a Leading
Edge model D.  It comes ready to run with 1 360K disk drive, 30Mb hard
disk, 512K RAM, and (uggh) a 4.77Mhz 8088.  Because of that last item,
I'm thinking of spending a few extra bucks for either the Mach-10 by
Microsoft (which I've been told is a 8088 running at 10Mhz), or a board
with an 80286 running at 6Mhz, which supposedly replaces the 8088.

(NOTE: Please don't ask why I don't simply buy a different machine - I'm
getting this one at a price too low to print).

Anyway, I have a few questions regarding the above cards.  Responses,
positive *and* negative will be greatly appreciated.

Microsoft Mach-10:
-  Anybody have any experience with it?  Approximately how much more
   speed will it give the PC?  Does it lose any compatibility at the
   higher speed?

Tech PC 286 board:
-  I've been told its the only 286 board deemed officially compatible
   with Leading Edge.  Any truth to this?  Are other boards available?

-  Does the presence of the 80286 now make the machine an AT clone, an
   XT clone with an 80286, or some bizarre hybrid (maybe a XAT :-) )?
   
-  Must I then look for sofware which runs on an PC/XT only?  More
   important, how about hardware - do I look for XT or AT compatible
   add-on boards?

Thanks in advance.

P.S. With the coming of the 80386, does anyone expect 386 boards to be
produced to *really* speed up a good ol' PC? (For all I know they already
exist!!)
