Has anyone ever worked with the obscure 3com Audrey device? I had never heard of it until finding one cheap at Goodwill. It’s missing the power cable, which I’ve been able to find only a little information on. The plug is an 8-pin DIN (I think lol), with 3 3.3v lines and 2 5v lines, and the rest are all grounds. I have a matching DIN plug on some other cable but cannot for the life of me find a pinout showing which voltage goes where…

Does anyone have a clue??

If you can get it open, it shouldn’t be too difficult to trace the pins on the connector to the VCC/VDD pins of some of the chips inside. Just look up the datasheets of some likely-looking ICs and set your DMM to its audible continuity setting.

On the other hand, if you just want to plug it in, I found this: http://www.ebay.com/itm/151977561033 (this page gave me the number to search for: 1.015.1494-00)

BTW, out of curiosity, how did you figure out the number and voltages of the pins, but not their actual assignments?

Out of curiosity, how did YOU find that listing?? Haha, thanks a lot for it- the seller lives within an hour of me so I’m hoping to get it fairly quickly. Any leads on some copies of Dragon Hopper in my area as well?

So I disassembled the whole thing, looked all around and couldn’t really figure it out. The attempt was a little bit half-assed because I had better things to be working on. The DIN plug was crowded by some other components I think, I’ve kind of forgotten exactly what problem I had. I did see some chip pinouts with 3.3/5v but it didn’t seem worth the bother to backwards-engineer it :p

The data I did find came from the Audrey hacking Wiki site or some random forum post- somebody listed the partial pinouts for those interested in modding the LCD screen or making a battery setup. Only one link to a real pinout existed, and it was as dead as the Audrey.

I sometimes forget that there are those whose search-fu is not as strong as mine… Continue your training and you will achieve mastery in due time, grasshopper 😉

What happened when you checked continuity/resistance from one of said power pins and pins on the DIN connector?

Did you try the URL in the Internet Wayback Machine?
