A reader of this blog has kindly donated the US version of the preloaded software for the PS/1 types 2133 and 2155 models in the Fall 1992 product line (ISA board).

I recently won an eBay auction for a PS/1 type 2133 model 451 (EMEA market, roughly equivalent to the US model S48) with a 486SX-25 (with FPU/Overdrive socket), 2MB RAM, 85MB HDD, and an integrated VLB Cirrus Logic GD-5426.
To my great surprise inside the puny hard drive I found a complete backup of the original preloaded software (which I obviously used to restore my machine to the factory conditions).
So here it is in all its glory (it’s italian software, sorry non-italian speakers…):
PS1_2133_2155_Spring93_HDD_Files_IT.zip – IBM PS/1 2133 HDD files Italian version
The same set of programs was probably used for all the other models in the same spring 1993 product line, type 2155 included. But I’m not sure about this so if you have more info please let me know.
A new version of IBMulator, the PS/1 emulator, is finally ready. In version 0.7 you’ll get:
- Better emulation of HDD and FDD with more realistic timings.
- Sound FX for FDD, HDD and the system unit.
- Various bug fixes.
The configuration file (ibmulator.ini) has changed so, if you are upgrading, delete or rename the old one to recreate.
I’m launching the new HOW-TOs section with a guide about how to use a standard, cheap 1.44MB 3.5″ drive as a replacement for a broken PS/1 floppy drive, which has a non-standard interface.
Thanks paperinik77pk for the help!

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.
