	   Blurb from the user manual ...

	o  The DOS-73 System gives you the best of both worlds --
	   UNIX and DOS.  With DOS-73 you can run most programs
	   on your AT&T UNIX PC (PC7300, 3B1) that can be run on
	   the AT&T 6300 and IBM PC compatibles.

	o  DOS-73 hardware is a UNIX PC coprocessor card equipped
	   with an 8Mhz, 8086 CPU, which can be augmented by an
	   optional 8087 numeric data processor.  The DOS-73 hardware
	   has 512K Bytes of main memory.   

	   In addition to supporting the UNIX PC peripherals, the
	   DOS-73 hardware supports its own independent I/O in the
	   form of an RS-232C async. serial port, configured as 
	   COM2:.  This port can be used for a local serial printer,
	   external modem, or any other serial device.

	o  DOS-73 software implements MSDOS 3.1 as a task on the
	   UNIX PC, using the DOS-73 hardware to emulate an IBM PC
	   with Hercules graphics.  A DOS-73 session can run on the
	   UNIX PC monitor or as a remote task with an auxiliary
	   terminal.

	   DOS-73 let's you create up to 256 virtual disk. (volumes
	   can be defined as C:-N:

	   Allows data interchange between the DOS file system and
	   the UNIX file system.

	   DOS-73 uses the UNIX PC internal modem to provide *Hayes*
	   compatible 300/1200 baud modem support for DOS programs.
