Vintage Commodore VIC 20 Power Supply 4 Pin Female Adapter (P/N 251052-02, Antenna Switcher, & Channel Selector ALL UNTESTED. I have no reason to believe they do not work; as far as I know they worked the last time they were hooked up to the VIC 20. However I can't test them as I already sold the untested computer unit a couple weeks ago because I couldn't find these anywhere in my house! Well of course I found them NOW. Anyway, if you have any other questions, just ask.
About me: I scout and re-sell interesting vintage items to raise money to help care for our daughter with autism. Your purchases are more appreciated than you'll ever know. Thanks for reading all the way down to here, and for peeking at this item. Have a wonderful day!
