Matthew SparbyFor nearly 5 years, I've been trying to figure out what this adapter is supposed to connect to. It's still a mystery. Someday, the right person is going to see this post and they'll finally solve this puzzle.
MufasaSo matching up the ports with their names has me really focused on the mouse port.
Is the intent to use a mouse and serial connection simultaneously or is it that this one cable represents one mouse (serial mice for Mac/PC)? 🤔
That isn't your run of the mill PS/2 mouse port either. It's a bus mouse port. Perhaps this is from a 3rd party product that bundled with a Microsoft InPort ISA card and a Microsoft bus mouse?
All signs are that this is 3rd party, proprietary & uncommon.
@ne1for23 Once upon a time, this exact cable was for sale on ebay. I messaged the seller to see if they knew what it was for (there was nothing in the description) but they never responded.
What did they even call it in their listing?
