| Build itChecked Jul 27, 2026 | Apple2-IO-RPiby TJ Boldt | Connects a Raspberry Pi Zero 2 W to an enhanced Apple IIe for virtual disks, networking, Linux commands, and file transfer. The upstream project describes Revision 7 as a prototype rather than a finished product. Most development and testing used an enhanced Apple IIe with the card in slot 7; the firmware assumes the slot 3 80-column card and lowercase support. A Pi Zero 2 W can consume roughly 170 to 250 mA from the Apple II's 500 mA total slot budget. Revision 6 and later can use external USB power after the documented jumper change, but the firmware will hang if the Pi is not powered. |

| Build itChecked Jul 27, 2026 | BMC64 PCBby Andy Minchin | 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. |

| AvailableChecked Jul 15, 2026 | Keyrah V3by Individual Computers | Turns supported classic-computer keyboards, digital joysticks, and analog paddles into USB HID input devices for a modern PC, Mac, or Raspberry Pi. The maker's store listed Keyrah V3 for immediate delivery on 2026-07-15. The box includes the circuit board and printed manual but no USB cable. Individual Computers has stopped ordinary shipments to the United States; its stated exception requires a forwarding service and wire-transfer payment, so US buyers should also check the official reseller list. |

| Build itChecked Jul 27, 2026 | MT32-Piby Dale Whinham and RetroDreams | Adds low-latency Roland MT-32 emulation and SoundFont synthesis to an ITX-Llama or MIDI-equipped vintage PC. The preconfigured RetroDreams package reported Sold out on 2026-07-27. The GPL-3.0 upstream project still provides source, releases, and setup documentation, although its maintainer says further releases are unlikely. Users must supply legally obtained MT-32 or CM-32L ROM images; they are not included in the retail package or upstream download. |

| AvailableChecked Jul 25, 2026 | Pi1541by Pi1541 project | Cycle-exact Commodore 1541 disk-drive emulation using a Raspberry Pi and SD-card disk images. Retro Electronics listed one assembled Option B Pi1541 Hat in stock on 2026-07-25. The Hat is the only supplied part; add a supported Raspberry Pi, SD card, serial cable, legal drive ROM, quality USB cable, and at least a 2.5 A power supply. The official project does not support Raspberry Pi 4 or 5. |

| AvailableChecked Jul 27, 2026 | RAD 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. |

| Build itChecked Jul 27, 2026 | Sidekick64by Frenetic | Uses a Raspberry Pi cartridge to emulate memory, sound, cartridges, ROMs, and file-loading functions across several Commodore 8-bit systems. The open project publishes Gerbers, BOMs, software, and case files for full-size and Zero boards. Retro-Updates' assembled Sidekick64 Zero was out of stock on 2026-07-27 and excludes the Raspberry Pi Zero 2. The maker calls the project a personal playground and warns that unsupported images, timing glitches, and unsafe cartridge combinations remain possible. |
