Possibly one of the most frustrating things about the IPX, Solaris, and workstations in general is the difficulty with finding software.
My recollection of the experience in the nineties was that licensing was tightly controlled through mechanisms such as flexlm. Often software was node-locked so it could only be used on a single machine and often software required an annual subscription.
Open source software is available, but this is much harder than it once was. Sun used to distribute this at no cost, but now it is behind a pay wall. Perhaps the sources are all readily available somewhere.
The best source of freeware i found is:
https://www.ibiblio.org/pub/packages/solaris/sparc
There are a few other packages lurking around in other places, such as archive.org, eg Wordperfect and Netscape.
