IBMulator v0.12

IBMulator v0.12 with the Munt MT-32 emulator

Changes since v0.11:

  • MIDI output support
  • Roland MPU-401 emulation
  • Sound Blaster 2.0 MIDI emulation

New ibmulator.ini settings:

  • [midi] to configure the MIDI device
  • [mpu401] to enable and configure the MPU-401 card

Limitations:

  • MIDI output only, no input.
  • For Sound Blaster MIDI emulation only SB-MIDI mode is tested; UART mode, while emulated, is completely untested (and probably broken) as I don’t know of any program using it (please suggest).
  • Only MT-32 SysEx messages are saved in save states.

Windows binaries are compiled and tested on Windows 10 Pro 19.09 with the latest MSYS2 release.
Linux binaries are compiled on Ubuntu 18.04 and tested on 20.04. With the provided Linux binaries you’ll get better (~10%) performance compared to v0.11 since I started using GCC 10 (ymmv).

PS/1 Spring 1994 Multimedia Pack CD

PS/1 Multimedia Pack CD, P/N 04H5920, US version

PS1_Spring94_Multimedia_Pack_CD_04H5920.zip

Software included:

  • Sample Photo Images
  • Original PS/1 Software Backup
  • Microsoft Multimedia Pack 1.0 (including: Hyper Guide, Multimedia Tour, Music Box, Media Browser, Screen Craze, and Vidtest).

This CD was probably bundled with all the PS/1 Multimedia (MM) models from the Spring ’94 lineup (2155 MM and 2168 MM).

Thanks WhiteKenny!

IBMulator 0.11

Changes since v0.10:

  • Creative Sound Blaster 2.0 emulation
  • Dark style and Zoomed in view for the Realistic GUI mode
  • Joystick axes and buttons remapping support
  • Adjustable emulation speed, from 0.01% to 500%
  • Bug fixing, especially in the audio mixing department

The Sound Blaster DSP v2.01 emulation is a brand new implementation (except the ADPCM decoders taken from the DOSBox project). I tested it as much as I could but I still expect problems, so bug reports are very much welcome.
Adjustable emulation speed was already somewhat implemented, but it was so broken that I consider it a new feature.

New ibmulator.ini settings:

  • [sblaster] section to set up the Sound Blaster;
  • [gameport] section to enable/disable port emulation and set joystick mappings;
  • realistic_style and realistic_zoom settings in the [gui] section, to set up the new Realistic GUI style and zooming functions;

PS/1 2133 Spring 1993 UK preloaded software

Preloaded software for the PS/1 2133 Spring 1993 UK

PS1_2133-451_Spring93_HDD_Files_UK.zip  – HDD software, Spring 1993, model 2133-451
PS1_2133-451_Spring93_HDD_Recovery_UK.zip – same software but as a recovery disk set.
Software included: MS DOS 6.0, MS Windows 3.1, MS Works for Windows, PS/1 Tools and Welcome, Recovery program, Cirrus Logic video drivers.
It’s the original software that was preloaded on the 2133-451 (486 VLB) but it was certainly installed on many other PS/1 models of the same period sold in the UK. Unfortunately I can’t verify.

Thanks Scott!

IBMulator 0.10

Changes since 0.9:

  • Video capture. Use the CTRL+F7 key combo to start/stop recording.
  • New SDL 2D renderers. Useful if your system doesn’t have proper OpenGL 3.3 drivers.
  • Native file dialogs, so you can use your OS’s standard file dialog if you need to.
  • Revamped keymap system: now portuguese, swedish, and other keyboards with dead keys should work.
  • New framecapping mechanism.

IBMulator 0.9

After more than 3 years since the last 0.8 release and almost a year since the last beta, IBMulator 0.9 is finally here!

Here are the most important changes since 0.8:

  • IBM PS/1 model 2121 emulation (80386)
  • VGA rendering is now scanline based for resolutions below 640×480: this allows for proper rendering of most demos, intros, and games that rely on per-scanline effects.
  • Audio card channels can be filtered with DSP filters, such as low pass and high pass; this is useful for example to recreate the sound of the original PC-Speaker.
  • ATA controller emulation
  • New synchronization options like vsync and framecap to fine tune the emulator for your particular system and/or taste.
  • A truckload of bug fixes

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

Read the README and go to the project’s homepage for more info.

Unfortunately, despite my best efforts, IBMulator is far from being bug free, so head to the issue tracker to get the list of known bugs.
