Sources for my65816 FPGA computer
I am mainly working on this project because I want to fool around with FPGA The aim was to implement a 65816 machine which uses a OS like the one found in the Atari XL/XE. Apart from the basic (kernel)-OS, nothing is compatible or even like the original Atari XL/XE series.
