Emulates Atari 8-bit disk drives from SD or MMC cards through the SIO port.

Lotharek offered the Biggus Dickus, metal-cased XL and XE, and color variants through login-to-buy paths on 2026-07-27. The metal-cased versions include an SIO cable, while the base Biggus Dickus listing includes neither cable nor SD card; other listings bundle those accessories with the same hardware. The official project also publishes Eagle schematics and boards plus firmware, making a DIY path possible. Upstream firmware reached 3.3 in 2023, while Lotharek says its assembled versions use customized 3.1 RC2 firmware, so do not assume identical features without checking the installed version.

Replaces an Atari ACSI hard disk with SD or microSD media in external, direct-plug, or internal Mega ST-family forms.

The internal, cased external, acrylic-case, and Mini pages exposed order paths on 2026-07-27. No form includes storage media. The current grey cased and internal revisions use USB-C, while the acrylic and Mini pages specify Micro-USB; a 5 V phone charger is not supplied. The cased units need a separately sold DB19-to-IDC20 ACSI cable, the Mini plugs directly into ACSI, and the internal unit needs a separately sold Mega ST or Mega STE adapter. The current cased page contains an older Micro-USB FAQ despite its revision notice saying USB-C. Older TOS versions can be slower or unsafe with DOS-compatible media, and some Atari DMA circuits or modern high-capacity card pairs need the documented troubleshooting or clock-capacitor fix. The optional DUCKBILL flasher requires a direct, bidirectional PC parallel port and Windows XP DOS console.
