Colecovision Adam Controller Adapter 9 Pin Converter Accessory Vintage

This is a vintage hardware accessory for the ColecoVision / Coleco ADAM ecosystem.

Specifically, this is the ColecoVision Roller Controller Adapter for the ADAM Computer Module (often referred to as the ADAM Power Adapter block).

What it does:

• The Problem: The ColecoVision\'s official Roller Controller (trackball) required its own power pass-through connection. However, when owners upgraded their system with the ADAM Computer expansion (Expansion Module #3), the standard power routing configuration changed because the ADAM printer supplied power to the memory console.
• The Solution: This pass-through adapter block plugs into the ADAM memory console\'s power socket. It allows you to hook up the printer power cable (to the side marked POWER) while simultaneously plugging in the Roller Controller\'s power connector (to the side marked ACCESSORY) so you could use the trackball peripheral on an ADAM system.
