It looks like we have reached 50 carts been both forums. Recently I received a new book "Atari Basic" published by Duddie and his new XE keyboard mylars. Both of those products are top notch and I am sure that he will deliver.
I am not a creator of it, I only repeat what I have read on atari.area forum. We can call it DragonCart II. It should have the same features with some improvements. From what I understood, some of the work will be off loaded from Atari and taken over by cart chipset.
