| AvailableChecked Jul 24, 2026 | AVGCART, SUBCART, and DUMBCARTby MiscRetro | A family of SD multicarts for Atari 8-bit computers, ranging from cartridge loading to disk, tape, memory, clock, and audio expansion. All three product pages showed In stock and Add to cart on 2026-07-24. Optional SIO, ECI, PBI, and DAC cables are separate. SUBCART's extra functions need ECI or PBI, and the maker does not recommend them on a machine with U1MB or another third-party internal memory expansion. |

| Build itChecked Jul 25, 2026 | SDrive-MAXby KBr | Emulates Atari SIO disk and cassette drives from microSD storage with an Arduino and touchscreen. The Brewing Academy kit was sold out on 2026-07-24, but the firmware and build files remain public. Its kit still requires assembly and part of an SIO cable. The official project strongly recommends external power because the approximately 150 mA load exceeds the Atari SIO specification; follow its wiring instructions carefully to avoid back-powering the computer or device. |
