Coleco Telstar Arcade AC Power Adapter - Model 6041
(Coleco - 1977)
This is a replacement AC power adapter for the Telstar Arcade that supplied 9v DC to the unit. With vintage systems like this, it is always a good idea to have a spare, because when you need one, these vintage adapters are virtually impossible to find... and let's face it, hooking your Telstar Arcade up with a modern AC adapter is just, well icky.
The plain white box for this 9v DC unit contains the power adapter and paperwork.
