Here I found some interesting files of what appears to be a HDD dump of a PS/1 model 2121 (386sx). It seems complete, with the tutorial, MS Works, IBM DOS and online service software.
From those files I’ve created an HDD image for emulators and a set of floppy images (to transfer the files to a real machine or a bigger HDD image). It’s an educated guess of what could have been the original software for the 2011.
Programs work and versions seem correct, but, if you’re concerned about historical correctness, keep in mind that this software is not from a 2011.
