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.

Breaks out compact Macintosh power rails and video signals for custom logic-board projects.

JCM showed 17 SE/SE30 units and 6 Classic/Classic II units in stock on 2026-07-24. These are custom conversion and test-bench parts, not drop-in upgrades for intact computers. The two Macintosh groups use different J12 signal mappings, so use only the version intended for the installed logic board. JCM recommends 16 or 18 gauge leads with a modern ATX supply on the SE-family board.

Converts raw compact-Mac video to VGA, with optional power integration for bare logic-board projects.

On 2026-07-24 JCM showed 11 onboard-VGA and 41 Extended MacPicoVid boards, 56 MacPicoVid SE-COMBO boards, 2 IDC12 boards, 19 SE-TOPPER boards, 46 128K/512K/Plus adapters, and 32 Classic adapters in stock. Standalone boards require separate 5 V USB power and host wiring. The power-integrated products are for a removed logic board or custom chassis, not a drop-in external-video port for an intact computer.
