I'm relatively new to this so forgive what I'm sure is a really simplistic question, but I haven't had any luck finding the answer. I'm really interested in restoring and modding game consoles, and I really want to do things right. When I look to obtain an ac adapter for some of the older devices I like to try and find an OEM adapter that was originally shipped with them, but even those can be challenging simply because of the age of the 'wall wart', so I also look to get a quality alternative that meets the requirements it was designed for. This has brought me to my question...
When looking at the details on the ac adapters I find some are labeled as having a 9V output (for example), while others have 9VDC or 9VAC. Older console adapters don't consistently have the best info, as you can imagine, but even new ones have information on them like this. I'm wondering why they wouldn't all use either VDC or VAC? Does the use of just "V" indicate VDC, or something else entirely?
I figure some of the older consoles were designed to run off batteries (like the original Magnavox Odyssey) so they would use a VDC adapter, but I'm not sure. I want to avoid toasting a device with old circuitry by making an error, so this is one of the things I'm looking to learn to help me make the best choices.
Apologies if this has been covered in previous posts... I looked but couldn't find anything.
Thanks!
