A8PicoCart (UnoCart on a Raspberry Pi Pico clone)
A multi-cart for the Atari 8-bit (XL/XE) family. Plug it into a PC via USB and it mounts as a USB Mass Storage device — drag and drop your ROM, CAR, XEX, and ATR files onto 16 MB of onboard flash, then plug it into your Atari.
What you get
One (1) A8PicoCart, assembled, programmed, and ready to use.
Designed by
Robin Edwards. The A8PicoCart is the Raspberry Pi Pico successor to Edwards' earlier UnoCart design — same idea, simpler hardware, lower cost. Open source. Source: https://github.com/robinhedwards/A8PicoCart
How to use
Connect to your computer via USB. The cart appears as a removable drive. Copy your CAR, ROM, XEX, and ATR files to it. Unplug from the computer, plug it into the cartridge slot of your Atari, and a file-selector menu appears on power-up. ROM and CAR files boot as if they were original cartridges; XEX files launch through a built-in loader. Limited ATR support is included — enough to do some BASIC programming and save work back to an ATR file.
Returning to the menu
After loading a file, press reset on the cartridge — the Atari will crash. Press reset on the Atari itself to return to the menu. (Normal behavior, by design.)
Important: Never connect the cartridge to a PC and the Atari at the same time. Doing so can damage the Atari and/or the PC.
