As a kid, [Boisy] cut his teeth on the TRS-80 Color Computer. It was a wonderful machine for its day, featuring a relatively powerful Motorola 6809 CPU. Although his CoCo was theoretically more powerful than its Commodore and Apple contemporaries, the graphics and sound capabilities of [Boisy]‘s first love paled in comparison to his friends 6502-based machines. A little jealously and thirty years go a long way, because now [Boisy] is adding a 6809 microprocessor to the 6502-based machines Atari put out. (http://liber809.blogspot.com/)
[Boisy]‘s goal for his Liber809 project was simple: Put a 6809 CPU in an Atari XEGS (http://en.wikipedia.org/wiki/Atari_XEGS) and get NitrOS-9 (http://sourceforge.net/apps/mediawiki/nitros9/index.php?title=Main_Page), the Unix-like OS for the TRS-80 CoCo running on his Frankenputer. After a few months of work, [Boisy] completed his goal (http://liber809.blogspot.com/2012/03/dual-cpu-mission-accomplished.html) and more so: the Liber809 also works on the Atari 1200XL (http://liber809.blogspot.com/2012/03/1200xl-success.html).
To put [Boisy]‘s work in perspective, it’s like he took a Macintosh from 1993 and made it run on an Intel 486. While that’s not a terribly accurate analogy, we hope our readers will understand the fortitude needed to make a computer run on a completely different processor.
After the break, you can check out a neat demo app written by [SLOR] from the AtariAge forums showcasing a 6809 running in a machine designed for a 6502. Awesome work for all involved
