Build itChecked Jul 27, 2026A2USBby ThorstenBr

Repurposes supported Raspberry Pi Pico Apple II video cards as a USB HID mouse interface.

A complete setup needs a supported A2VGA Revision 1.6 or modified older A2VGA or A2analog card, a Micro-USB-to-USB-A adapter, and a driverless USB HID mouse. USB hubs are not supported. Installing A2USB removes the card's VGA function until different firmware is loaded. Remove the Pico or card from the Apple II before using BOOTSEL to update firmware, and choose the PAL or NTSC build with the appropriate 50 or 60 Hz interrupt default.

Connects a modern Mac to Apple and PC floppy drives for disk imaging, flux capture, analysis, and writing.

The official store marked Applesauce+ sold out on 2026-07-15. The client requires macOS 10.13 or later; Windows and Linux use requires macOS virtualization. Current boards use a 12V adapter, and the power adapter and PC-drive cables are sold separately. Flux imaging with Apple-compatible 5.25-inch drives requires a sync sensor, which is also strongly recommended for Apple 3.5-inch drives; PC drives do not need one.

Recreates a C64 as a complete FPGA-based keyboard computer with original peripheral interfaces plus HDMI, USB, microSD, Ethernet, and Wi-Fi.

On 2026-07-27, the breadbin BASIC Beige model exposed a Buy Now path and regional stock, while the slimline Commodore 64C Ultimate was a paid preorder scheduled for factory dispatch on September 15, 2026. The internal microSD card is sold separately. The externally accessible user port requires a separate adapter. Commodore warns that Ultimate64 and C64 Ultimate hardware and firmware are diverging; unsupported firmware can leave a machine nonfunctional and resulting damage is outside free support, warranty service, and replacement.

Build itChecked Jul 15, 2026FluxEngineby David Given

A DIY USB floppy interface and cross-platform toolkit for reading and writing unusual disk formats with a conventional PC floppy drive.

Building the original interface requires a compatible PSoC 5 development board, a floppy connector, soldering, a conventional PC floppy drive, cabling, and drive power. The project warns that not every listed format has been tested on physical disks; its dinosaur markers identify encoders or decoders based only on captured data. Copy-protection schemes are not a core focus.

Connects a modern computer over USB to a separate floppy drive for reading, analyzing, and writing disks at the raw flux level.

An assembled board still needs a compatible Shugart-interface floppy drive, ribbon cable, USB cable, and suitable drive power. Older 5.25-inch and 3-inch drives often need 12V or a separate supply. Remove the write-enable jumper while preserving originals. Apple II, Macintosh, and Commodore 64 GCR disks can require trial and error with drive choice.

Streams read-only floppy images from a modern USB host to compatible 34-pin drives or an Amiga external-floppy adapter.

The standalone unit, cable set, and Ami2PC bundle exposed current login-or-register-to-buy paths on 2026-07-27. The official HxC home page and release notes show that the software project remains active in 2026. The unit needs a modern computer running the HxC host software and emulates disks read-only. The standalone set includes a 40 cm floppy ribbon and USB A-to-B cable; Ami2PC instead adds the Amiga external-floppy adapter. Never connect or disconnect the 34-pin or Amiga-side cable while USB is attached; disconnect USB first. Ami2PC can use Amiga disk-copy software to write a real disk in DF0 from an emulated DF1. Its early-boot workflow needs Kickstart 2.0 or newer. The seller still does not identify which oldest Amigas need its unspecified modification, so do not rely on early-model boot support without separate instructions.

Build itChecked Jul 24, 2026ISASTMby Manawyrm

Implements an experimental STM32-based USB host for operating ISA cards on an external backplane.

Treat this as an unfinished development platform, not a turnkey USB-to-ISA product. The repositories provide Revision A fabrication files and early STM32 firmware but no documented host application, VM integration, release, or end-user procedure. A linked 2020 development thread demonstrates predecessor Arduino Mega experiments with serial ISA reads and writes, isapnptools, an Aztech sound card, and PCem, but does not establish that those workflows were implemented for ISASTM. Revision A has signal-integrity and reset-pull-up errata, and USB High-Speed is untested and may not work. The required ISA backplane supplies power.

Replaces a failed or missing Atari POKEY with an updateable FPGA module in the original DIP-40 socket.

The product exposed a login-or-register-to-buy path on 2026-07-27. Installation is solderless only when the computer already has a compatible DIP-40 POKEY socket. This is a functional FPGA replacement, not a transistor-level NMOS clone; the seller warns that software depending on undocumented analog behavior or exact electrical characteristics may behave differently. The built-in USB port allows future firmware updates.

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.

Open internal video-overlay module that displays expansion status and other configured messages over C64 composite or S-Video output.

The maker offered assembly kits by email for 25 EUR including regular worldwide mail on 2026-07-30, with a limit of two per person. Stock is kept when practical, but prepaid production batches can take several weeks. The kit includes the PCB, a preprogrammed ATmega, and board components, but not the computer-specific wiring. C64 installation is an advanced internal modification: use amplified luma from A/V pin 1 for S-Video or composite from pin 4, never the unamplified VIC-II luma signal. Driving both outputs requires an expert RF-modulator connection, and excessive overlay brightness can disrupt sync.
