In the late 90s a lot of these machines were being abandoned. Properetary Unix was dying due to Linux, and non-intel CPUs were also getting crushed. Plus there was the dotcom crash meaning defunct companies got rid of gear. In those days I got an extremely cheap Sun workstation on ebay as an example. Anyway, I guess supply is low but there are still nerdy people who think an old Unix machine is cool. (I'd take one running Irix just to play with for sure.)
