PS/1 2133 IT preloaded software

PS/1 2133 welcome

The Windows welcome screen

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.

IBMulator 0.7

A new version of IBMulator, the PS/1 emulator, is finally ready. In version 0.7 you’ll get:

  1. Better emulation of HDD and FDD with more realistic timings.
  2. Sound FX for FDD, HDD and the system unit.
  3. Various bug fixes.

The configuration file (ibmulator.ini) has changed so, if you are upgrading, delete or rename the old one to recreate.

IBMulator 0.6

The realistic GUI mode

The realistic GUI mode

In this version:

  • Realistic GUI mode
  • New key bindings (for eg. Ctrl-Alt-Del and SysReq)
  • Bug fixes (Windows 3.0 now works)

The Realistic GUI mode is for the retro enthusiasts who want to truly experience the PS/1. In this mode the system is rendered in its entirety, monitor included. There are no additional buttons or controls except for the originals: volume, brightness, contrast, power, and floppy (you need to use the key bindings for any extra function.) The PS/1 model 2011 is 32 cm (12.6″) wide and 34.9 cm (13.74″) tall, so you need at least a 24″ 16:10 monitor in portrait mode (rotated) to render it at real size.

The configuration file (ibmulator.ini) has changed a lot, with a new section. Delete the old one to recreate.

IBMulator 0.5

Windows 3.1

Windows 3.1

In this version:

  • Joystick emulation
  • Custom HDD type
  • ROM load from bin files and directories
  • Lots of bug fixes

With the custom HDD type (45) you can use a drive with 1024 cylinders, 16 heads, and 62 sectors per track, for a maximum of 496MiB. Theoretically the maximum value for sectors per track would be 63, but a bug in the BIOS prevents the system to correctly format the drive.

Among the bug fixes: Windows 3.1 and MS-DOS 6 now work.

The Windows version has been tested only under Windows 8.1 and the Linux version under Ubuntu 14.04

The configuration file (ibmulator.ini) has changed. Delete the old one to recreate.

US version pre-loaded software

IBM PS/1 Club

IBM PS/1 Club

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.
