The AT&T PC6300 can be upgraded to a PC6300+ with a Technician installed
upgrade kit.  The approximate cost is $3000 dollars depending upon
what is in your machine when you need the upgrade.  The upgrade
involves changingout the Motherboard, Display Controller Board,
Bus Board, HDU controller, HDU if necessary, and floppy drive to
1.2 meg if desired.  Just about the only things that remain are
the cabinet, power supply, and monitor.  They keyboard may even 
get replaced if you want (the plus comes with a slightly different,
but compatible keyboard).  AT&T takes back all old parts.
As far as compatibility, what you get is a 6300+ and almost anything that
runs on the 6300 will run on the plus.  You can even run UNIX System 
5 and Simultask which allows you to run most MSDOS programs under unix.
Also, the 1.2 meg floppy drive can read 360K diskettes that were written
on a 360K drive, so porting files from one to another is no big deal.

For more info and exact pricing for the upgrade kit, call
AT&T National Marketing at 800-247-1212.
