COSI has an FPGA (field-programmable gate array). It's not a very impressive one, but it's something to get started with. It's a RioRand® EP2C5T144 Altera Cyclone II FPGA Mini Development Board. It cost us about $25 during the Spring 2015 semester.
So far we have not had much success using it under platforms other than Windows XP.
According to one Amazon review, it should be programmed with Quartus Version 11.0 Build 208 07/03/2011 SJ Web Edition, Service Pack 1.
The LEDs are on 3 7 and 9, and the switch is on 144.
