Connecting ATT 7300 to SGI network

[Bill Lasher]

We have a lab of SGI personal IRIS machines.  We would like to attach a PC so w
e can transfer CADKEY files from DOS based PC's.  We have the opportunity to ge
t two ATT 7300's for free, but we don't know much about them.  Can the ATT read
 DOS files without a special board?  What would it take to hook them up to the
SGI ethernet (running TCP/IP, NFS)?  Any suggestions would be appreciated.
