Incognito-Lite is a RAM module replacement board that adds Atari XL/XE compatibility mode to good old Atari 400 computer, providing up to 1MB of additional extended memory, 64k of base memory, USB flash-disk based mass-storage device and powerfull debugging options for real hardware debugging (you can set a trap on opcode, on adrress range or on access type) for quickly resolving issues you may have with your own written games or software that seems to work under emulation, but somehow fails when it comes to running on real hardware

This is second prototype of this board - previous was using SD/TF cards as a storage device, but since Atari 400 has very limited space to make such card removable i've decided to replace it with USB port you can easly make a hole for and buy front-panel mount cable adapters everywhere

This is still W.I.P. so please bear this in mind when ordering - this should not be considered final version, but it will provide basic functionality of older Incognito board for Atari 800 and mass-storage access as these parts are already tested while making other projects and code for hardware layer drivers was written

Having said this - enjoy.
