I hope Lenny doesn't mind that I plaigiarized his posting, but I also have one of these for sale and thought the extra info would be helpful. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- ** FOR SALE ** ** FOR SALE ** ** FOR SALE ** ** FOR SALE ** ** FOR SALE ** ###### ##### ##### ###### ##### # # # # # # # # # # # ##### ##### # ##### # # # # # # # ###### ##### ##### # ##### 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 (YES, included, even though was an option), 3 system software disks (drivers), 1 diagnostic floppy, 1 610 Terminal Support floppy. Original manuals. How much?? Well, let's say $300 + shipping. 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. If you're interested, please email me. First one interested gets it! Board works, and passes all diagnostics. If you want it a little cheaper, I could pull the 8087 chip... I could probably include some DOS software that I don't need anymore also, if you want. Again, I apologize for the almost word-for-word copy of Lenny's posting, but I'm reasonably sure he's sold his by now, and I have exactly the same thing, but with the original manuals included.
