		        UNIX PC DOS Coprocessor Board

	   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.


What you get...  You get the DOS-73 coprocessor 8086 cpu, installed
8087 math coprocessor (included, even though was an option), 3 
system software disks (drivers), 1 diagnostic floppy, 1 610 Terminal
Support floppy.  How much??  Well, let's say $300+shipping.   Where
could you get an IBM PC for $300! :-)  

Advantages...    let's you interact with your UNIX pc with UNIX and
DOS, emulates Hayes command set with internal modem (so programs like
Crosstalk XVI will work), you can set up small virtual partitions for
the hard disk, up to 256 can be created,  8Mhz clock speed, 8087 
coprocessor included (for faster math processing), good price! :-)

Disadvantages... you only get 512K memory, cannot be EXPANDED.  Only
supports Hercules graphics.   No manuals, although I could
probably photocopy my manual and add the copying costs...

If you're interested, please email me.  First one interested gets it!
Board works, and passes all diagnostics.
