I actually purchased GoBe Productive 2 for BeOS R5, and version 3 for Windows a couple of years later. It was my default office app for most of the decade. Itβs a pity that the source is lost, because it was a nicer app than StarOffice at the time (IMHO) and it might have survived in an open source format.
I have a copy of it for BeOS too. It runs on both PowerPC and Intel. It was pretty nice at the time. I'm sure it is incapable of doing anything with modern documents though.
One, but there were others. Moho comes to mind, but there were others such as Tune Tracker.. there was at least one DAW that came with BeOS and a custom app to run the hardware too. There were a few games.. Chorum 3 is one I have a copy of. There was a version of the Opera browser at one point too.
