 In 2007, Gary Becker began designing what would become the CoCo3FPGA on a Digilent XC3S1000 board.  In September of 2008 he created the CoCo3FPGA Yahoo! group and posted the files and documentation to support it.  As time went by there was pressure to port the HDL code to a more readily available platform, the Terasic DE1.  By May of 2010 Gary had posted versions of his design for both boards. Aside from the design of the main CPU core (6809) and the co-processor (6502) Gary has designed the other components in Verilog HDL.  From time to time he freely releases his source files so that others may port the design to other platforms if they wish.
-As of July 2018 the CoCo3FPGA group is comprised of over 430 members averaging over 100 posts per month since May of 2015. The group exchanges ideas on programming, development, NitrOS9, and new features. Any interested party may join by navigating to the [https://groups.io/g/CoCo3FPGA groups.io CoCo3FPGA group] and selecting 'Apply for membership in this group'. A request to join will normally be approved by a moderator in less than 24 hours.
