The IBM PS/1 model 2011 emulator.

It’s still in its infancy. It lacks a lot of features and has many rough edges, but I think it’s in a fairly usable state.
Even if it’s not complete (and it works only on Linux), I release the code following the motto “release early, release often”.

In the Download page you can find the ROM to use with the emulator and some other program, like a ROM dumper to dump your own ROM image. I’m currently looking for the US version and other international ROMs, so I can test and complete the emulator. Donations are welcome!

The PS/1 model 2011 emulator seems to function properly now. I had to fix a couple of strange bugs in the Bochs’ code (but I’m not confident enough to submit patches).

Now it boots without errors, the mouse driven interface is working correctly and it’s even able to launch some games.

No HDD or audio yet though, and the usability is almost nil (no gui).

I’ve been playing with a shader lately, namely the Timothy Lottes’ CGA monitor shader. It is promising, but it definitely needs some tweaking.

The emulator for this system is progressing well. The following is the screenshot of the fist time it successfully booted to the IBM’s 4-quadrant interface, directly from the system rom.

There’s still a lot to do. HDD and sound emulation are the biggest challenges.
