AvailableChecked Jul 24, 2026SCSI Adapter With Blinkenlightsby Tech By Androda

Adapts several common vintage SCSI connectors while eighteen LEDs expose signal activity for testing and troubleshooting.

JCM showed 34 units in stock on 2026-07-24. Connector orientation matters: align the PowerBook connector's marked missing pin, install the Centronics connector with its wider side toward DB-25, and expect the internal 50-pin female socket to be unusually tight.

Mac OS installations need suitable third-party formatting software. Hot swapping works only when the host operating system supports removable media and may require explicit unmount and mount operations.
