Restores spring-clip keyboard support while leaving clearance for internal Apple IIc expansion boards.

JCM showed 39 units in stock on 2026-07-24. It is intended for the Apple IIc spring-clip keyboard. Some case revisions require trimming plastic screw bosses, so inspect the exact case before installation.

Swaps a Commodore computer's two control ports while preserving both digital joystick and analog mouse or paddle signals.

The surviving AmiBay production runs are closed sales archives. COREi64's former product route is currently replaced by a store-wide notice saying the shop will return in Fall 2026, so no current C8D order path is verified. The original C8D maker site also failed Tavily extraction twice after the required retry and is recorded as WF-050.

Turns a spare compact-Mac logic board into a small desktop computer with modern power, display, and storage hardware.

On 2026-07-24 JCM showed 5 printed 128K/512K cases, 3 Plus cases, 2 SE/SE30 cases, and 5 Classic/Classic II cases in stock. This is an enclosure, not a complete computer: supply a working logic board, power and video electronics, storage, input devices, display, cabling, and other desired parts. GutBomb's printable design is CC BY-NC-SA and does not cover the separate electronics.

Convert the unusual HDI-45 video port on first-generation Power Macintosh systems to Macintosh DA-15 or VGA-style HD-15 output.

JCM showed five DA-15 adapters and seven HD-15 adapters in stock on 2026-07-24. The open designs remain buildable under a CC BY-NC 4.0 license. The HDI-45 pins are unusually thin and flexible, and the project strongly recommends its printed case for pin alignment and stability.

Provides a compact analog joystick for Apple II game ports, with kit and assembled configurations.

The product page explicitly said Out of Stock on 2026-07-24. The center may measure around 150 instead of 128, and kit builders may need to add or remove capacitors and adjust the trimmer.

Compact Apple II paddle controller offered as an assembled unit or a beginner-friendly through-hole kit.

The storefront listed economy, standard, and fully assembled configurations without an out-of-stock marker on 2026-07-24. Newer PCBs carry a correction sticker for a November 2025 silkscreen error.

Provides source files for a Cherry-compatible Commodore PET N-type keyboard with printable supports and keycaps.

The repository was actively updated in June 2026 and supplies PCB, firmware, support, test, and keycap files. It is an advanced source build rather than a complete retail kit. The maker built it principally for the Micro-PET and Ulti-PET family and explicitly says installation in an original PET is possible in principle but untested.

Open 90-degree cartridge adapter that brings a C64 cartridge upright and can include a reset button.

Sordan exposed an assembled C64 unit with a printed case and stand for dispatch in one to three working days on 2026-07-27. The open repository also provides fabrication files and a printable-enclosure link. A completed 2024-2025 seller run offered bare, kit, and assembled versions tested on C64 or C128 systems.

Adds firmware-controlled RGB lighting inside a C64 case fitted with an Ultimate64 mainboard.

Official construction and pinout documentation and multiple printable mounts remained downloadable on 2026-07-30. COREi64's assembled shop is closed for updates until Fall 2026, so no current prewired retail kit is claimed. Use firmware 1.10 or later and the exact 5 V wiring. The official guide warns that shorting 5 V to ground can burn a board component and applying 5 V to an FPGA pin can damage the FPGA.
