- IBM DOS R4.01
- System Tutorial
- MS Works 2.0
I received a couple of requests recently about the Model 2011’s RTC battery and how to replace it.
So I quickly arranged a mini how-to to explain the process.
Hope this helps.
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.
PS1_2011_HDDIMG_US.zip HDD image
PS1_2011_HDDBKP_US.zip Backup on floppy disks
PS1_2011_HDDFILES_US.zip Extracted files
While looking for some PS/1 screenshot, I noticed that the UK ROM I thought I have is most probably the US version. In fact in the UK version there’s no PRODIGY online service available (see picture, the telephone is missing.)
So I shrunk the F80000.BIN file to 256Kb, renamed it to FC0000.BIN and put it in PS1_2011_ROM_US.zip
Now I’m looking for the UK version, so as always donations are welcome. UK version found (see download page)
