New replacement for the analog-board to logic-board signal cable in four compact Macintosh models.

The JCM page showed 17 units in stock on 2026-07-24. Never use the cable to combine an SE or SE/30 board with a Classic or Classic II board: the identical-looking connectors carry signals on different pins, and mixing the two groups will damage the computers.

Breaks out compact Macintosh internal TTL video for an RGBtoHDMI or another compatible digital scaler.

JCM showed 11 units in stock on 2026-07-24. This is not a standalone HDMI adapter: it requires a compatible digital-TTL scaler and installation wiring. The onboard buffer is intended to protect the scaler from analog-board high voltage.
