An acquaintance referred me to this group because he thought someone here could help me out. I am looking for a copy of SunOS 4.1.3, preferably version C. Can anyone assist me in finding a copy for purchase? I have an old Sparc with a program titled SNAP that was written for this particular version of SunOS, but I do not have this version...only Solaris 2.0 and SNAP will not run on it. Thanks for your help! Chad Tillman chad(a)ti-law.com 704-458-2423
