Hatari 2.2.0 released

Hatari 2.2.0 has been released. Hatari is an Atari ST/STE/TT/Falcon emulator for GNU/Linux, BSD, Mac OS X, Windows and other systems which are supported by the SDL library. The Atari ST was a 16/32 bit computer system which was first released by Atari in 1985. Using the Motorola 68000 CPU, it was a very popular computer having quite a lot of CPU power at that time. Unlike many other Atari ST emulators which try to give you a good environment for running GEM applications, Hatari tries to emulate the hardware of a ST as close as possible so that it is able to run most of the old ST games and demos. Hatari is open source software and is distributed under the terms of the GNU General Public License (GPL). This new release – a year in the making – has a sizeable changelog, but I’m not exactly an Atari expert, so I’m not entirely sure which of the changes are the most exciting.

Introducing Darkstar: a Xerox Star emulator

Given its history and relationship to the Alto, the Star seemed appropriate for my next emulation project. (You can find the Alto emulator, ContrAlto, here). As with the Alto a substantial amount of detailed hardware documentation had been preserved and archived, making it possible to learn about the machine’s inner workings… Except in a few rather important places. Fortunately, Al Kossow at Bitsavers was able to provide extra documentation that filled in most of the holes. Cross-referencing all of this with the available schematics, it looked like there was enough information to make the project possible. This is an amazing project, and the article provides a lot of details about the process of writing the emulator. I’m definitely going to try this out this week to see if I can get it running. I’ve never used the Star, and that’s likely never going to change – they’re rare, expensive, and in museums – so this is the next best thing. I think most of us owe it to ourselves to try this out.

EmuTOS: a Free operating system for Atari computers

EmuTOS is designed to run on traditional Atari hardware (ST, TT, Falcon, based on Motorola 68000  or ColdFire microprocessors) and their emulators. It features functionality similar to TOS, which powered the Atari ST and its successors between 1985 and 1994. EmuTOS can run on real hardware, either as ROM replacement or from floppy, or on any Atari emulator such as ARAnyM, Hatari, or Steem SSE. EmuTOS is Free Software, and can run legacy third-party software on emulators without requiring copyrighted Atari ROMs, thereby avoiding legal issues.
