        A few people have inquired about multiport boards.  In the 
   June 5, 1989, _PC Week_, they reviewed eight add-in boards.
   I will summarize the review and include vendor names and 
   addresses.  I sent a letter to each company requesting spec.'s, 
   so if you need more information about any of these, let me know, 
   I'll be happy to share.
   STALLION AT-16P and ONBOARD IOP-16P:  The Stallion in 16-port 
   configuration is priced at $1,745; the ONboard with 16 ports and

   Intel Corp. 80186 processor.  Vendor provides support for 
   Microport Unix, Interactive Unix, SCO Xenix, IBM AIX for the IBM 
   RT, MS-DOS and VP/ix.  A device-driver-development kit is 
   available to allow installers to build customized support for 
   other systems.
