Loads cartridge images and XEX files from USB-managed flash storage through an inexpensive RP2040-based Atari XL/XE cartridge.

A8Renegade's live Shopify product data and collection reported the assembled cartridge orderable on 2026-07-27, despite a contradictory sold-out label in the rendered product page. The complete open design also remains buildable.

Generates crisp 640 by 480 VGA from Apple II video memory using a Raspberry Pi Pico bus-snooping card.

JCM showed 36 assembled A2 VidGA cards in stock on 2026-07-24, with firmware choices for Apple II and II Plus or Apple IIe. RetroFletch's A2 Analog seller was taking a break on 2026-07-27; its published board has a critical VGA IDC footprint error, so the cable's red wire must face the motherboard. A2 Analog can also conflict with some accelerators, card autodetection, CFFA3000, and ROMX configurations. Infinity Products' SMC A][ VGA Mini was out of stock, and Laser's assembled Mark Aikens variant showed zero stock. Choose the exact hardware and firmware branch rather than treating every variant as interchangeable.

Packages a Raspberry Pi 3B+ and RP2040 keyboard interface into an original C64 or C64C case as a low-latency BMC64 system.

Current shortboard and longboard v4.0 files and an easier-to-assemble v4.0.1A variant were available on 2026-07-27. No assembled seller was verified. A complete build needs both PCBs, components, assembly, a Raspberry Pi 3B+, Waveshare RP2040-Zero, microSD card, original C64 or Mechboard64 keyboard, suitable case, and power. BMC64 itself is not compatible with Raspberry Pi 4B or 5.

Provides two switchable 8 MB flash banks that can be programmed over USB without a separate ROM programmer.

Replaces the RC2014 CompactFlash storage module with microSD for CP/M 2.2.

Current kits are offered for Standard or Enhanced Bus, with the surface-mount microSD socket loose or preinstalled. The Standard Bus version needs the supplied jumper lead to connect /WAIT to the CPU module. The vendor page says RomWBW support is forthcoming, so this record only claims CP/M 2.2 support.

Runs a purpose-built Macintosh 128K emulator on a Raspberry Pi Pico with monochrome VGA and USB keyboard and mouse input.

Juicy Crumb exposed an Add to cart path for the assembled v2 carrier and an optional in-stock Raspberry Pi Pico on 2026-07-27. Check whether the selected package includes the Pico. A working setup also needs 5 V power, a VGA display or converter, USB OTG cable, mouse, and usually a keyboard or hub. The default flash-backed disk is read-only; writable storage requires a separately built SPI SD-card path. Building firmware from source requires a legally obtained compatible Macintosh ROM and disk image. The community UF2 creator was temporarily offline during this check.

An 8-bit ISA card with switchable classic sound-card modes plus MIDI, USB game-controller, and CD-ROM emulation.

Joe's Computer Museum showed the assembled PicoGUS 2.0 in stock on 2026-07-24. The official site also listed stocked UK and EU sellers. Open design files and build guidance remain available for people who want a DIY board.

Connects modern USB HID keyboards and mice to Macintosh computers through Apple Desktop Bus.

HIDHopper Base, Base with USB Hub Hat, and Hub Hat-only selections could be added to the JCM cart on 2026-07-24. The assembled QuokkADB Rev. 2022g remained sold out, while its Raspberry Pi Pico Community Edition remained buildable. HIDHopper's Hub Hat requires external USB-C power, must be power-cycled between Macintosh starts, and can otherwise exceed the host's ADB power budget.

Adds an 80-column VGA serial terminal with USB keyboard input, a buzzer, and microSD support to an RC2014.

The optional SD backpack is only for the earlier Pi Pico VGA Terminal. It requires PicoTerm 1.6.0 or later, can be ordered with its surface-mount socket preinstalled, and does not include the Pi Pico itself.

DIY RP2040- or RP235x-based replacement for one or two 6581 or 8580 SID chips, with optional FM emulation and paddle or mouse input support.

Choose the hardware design and matching firmware together. The official project documents different DAC, PWM, connector, line-output, and host-interface arrangements plus a list of preassembled sellers. Multi-SID or FM modes need the documented address-signal wires. Never power the module from USB and the Commodore computer at the same time.

Replaces the ball mechanism in an original Apple ADB Mouse or ADB Mouse II with an adjustable optical sensor while retaining the ADB interface.

Both $72.99 variants were out of stock on 2026-07-27: the Mouse II board since May 25 and the original wedge board since July 18. Match the replacement to the exact shell and board shape before ordering. The original ADB cable is required, and installation may require moving its four wires or connector. The USB-C connector changes settings and firmware; it does not turn the mouse into a USB device.

Displays Macintosh Portable video on a VGA monitor at 640 by 480 with centered 640 by 400 content.

JCM showed 46 Hardware Version 1 adapters in stock on 2026-07-24. Connect or disconnect only while the Portable is off. Never use a VGA extender cable between the adapter and computer; it can short and damage the Portable. Keep conductive objects away from the exposed connector pin carrying battery voltage.
