The ABBUC USB cartridge is a professionally produced USB host adapter for the Atari 8-bit computers.

The software for this cartridge is currently in very early beta development, but already understands keyboards, joysticks, steering wheels and other simple USB devices.

The USB cartridge chipset supports communication with both 'low speed' and 'high speed' USB 1.1 compatible devices.

The software for the USB Cartridge is completely open source and is part of the MicroUSB project. For up to date information on the state of the software support for this device, please visit the Atari XL/XE section of the web site.

As production hardware becomes available the available software and number of devices supported will certainly increase quickly.

The USB cartridge is designed by ABBUC e.V. and manufactured in co-operation with Atarimax.



Pre-orders for the first 100 USB Master cartridges will be accepted at the special price of only $39.99.

After the first 100 are sold, or 12/31/2023, the regular price will be $49.99 per cartridge.
