Jonathan “flashjazzcat” Halliday offers a working demo of the new multitasking graphic OS (Graphical Operating System, GOS) being developed for the Atari 8-bit computers.
The zip file contains ROM and ATR files that can be used with several programmable cartridges. There is also separated versions that uses Amiga and Atari ST mice.
Halliday is currently working to improve the system performance to display text and other improvements.
While it is expected that in the future GOS runs on XL/XE computers with 64KB the current status shows that a realistic configuration needs 128K RAM, a flash cartridge and a mouse compatible with Atari ST or Amiga.
Based on the video below, GOS looks really impressive, with a nice and crispy black and white interface showing good performance. Remember that it is a multitask operating system, an amazing feat for the good old Atari!
