IBMulator 0.9 beta1

Emergency release to resolve the mouse tracking issue under Windows 10 FCU, which rendered the emulator unusable.

This release adds this (quite big) feature:

  • PS/1 model 2121 emulation

The 386 emulation has still some issues though. Please see the GitHub’s issue tracker for more info.

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
