Anyone know for sure where I can get a free license and the important serials etc. for Free SCO Openserver 5.0.4 (product id : 280-920-102) and Free SCO Unixware 2.1 (product ids: 480-920-400 & 480-92A-400). Caldera don't appear to support older versions. I got given these CDs and I'd really like to be able to make use of them.
