AvailableChecked Jul 27, 2026Atarimax SIO2PC/ProSystem Interfaceby Atarimax

Connects Atari 8-bit SIO computers and disk drives to a modern host for peripheral emulation and disk transfer.

The official page showed USB and RS-232 ordering options on 2026-07-25. Select the interface and connector arrangement for the intended host software and SIO chain. An Atari SIO cable and the computer or disk-drive hardware needed by the chosen workflow are not included. The USB setup documentation is dated and lists Windows 95 through Windows 7, so confirm current host support rather than assuming modern Windows compatibility.

AvailableChecked Jul 27, 2026Lotharek SIO2PC / 10502PC Familyby Lotharek

Connects Atari SIO computers to a modern USB host, with 10502PC variants that can also image disks through a physical Atari drive.

The basic SIO2PC USB, 10502PC Revision 2, and USB-C Revision 3 pages all exposed login-or-register-to-buy paths on 2026-07-27. Host emulation requires a modern computer, FTDI serial drivers where needed, and software such as RespeQt or AspeQt. The basic interface's manual uses DSR handshaking, while the 10502PC pages specify CTS for SIO2PC mode. Physical-drive imaging requires a 10502PC variant, ALibPC, and the documented FTDI setup; launching ALibPC changes the adapter to 10502PC mode, and unplugging and reconnecting USB restores its default SIO2PC mode.

AvailableChecked Jul 27, 2026RAD Expansion Unitby Frenetic

Uses a Raspberry Pi cartridge to emulate up to 16 MB of REU memory or up to 4 MB of GeoRAM-compatible memory on a C64 or C128.

Retrobit listed five assembled cartridge boards with cases at PLN 93.50 on 2026-07-27. A Raspberry Pi Zero 2 W and microSD card are not included. The upstream project describes RAD as a playground for new features and documents machine-dependent timing and power limitations.

AvailableChecked Jul 27, 2026SIO2SDby Jakub Kruszona-Zawadzki and contributors

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.

Sold outChecked Jul 27, 2026TBA SIO2PCby The Brewing Academy

Connects an Atari 8-bit computer to a modern Mac or Windows computer for disk, cassette, modem, printer, and file-transfer emulation.

The Atari 8-bit collection marked all versions sold out on 2026-07-24. Dual-SIO versions can sit within an SIO chain; single-SIO versions must be at the end or on a splitter. All listed versions include a printed case and an 8 GB microSD card, but need a separate Micro-USB host cable and a Mac or Windows computer. Windows may also need a UART driver.

Build itChecked Jul 25, 2026XS1541by Nils Eilers and Andre Fachat

Bridges a modern computer over USB serial to Commodore IEEE-488 and IEC equipment, or supplies host-backed storage to a Commodore computer.

The maintainer explicitly calls XS1541 orphaned and reconstructed its documentation from an archived build guide. The surviving page provides a schematic, firmware, and detailed assembly and flashing steps, but not a turnkey current kit. The original board connector footprints are buggy: the narrow connector can short contacts unless the coding gap is physically corrected. A build also requires fine-pitch FT232RL soldering, ATmega programming, fuse setup, cables, and suitable host software.
