Atarimax – Maxflash – 1mb Flash Cartridge

The flash cartridge is a professionally produced, in-system reprogrammable flash-memory based cartridge for the Atari 8-bit computers.

While the hardware itself can be programmed with anything, it is also supported by an open-source multi-cart/disk-cart/banked-cart development system which is already robust enough to produce large multicarts/disk conversions without any programming by the user.

Its the intention of the initial 1mb cartridge project to provide a easy to use platform for homebrewing of inexpensive, legal multi-carts and other software, while being small enough to allow it to be completely and quickly re-programmed in the Atari itself, using only a standard floppy disk drive.
