Does anyone know what type of expansion card/port this is?
How about a photo of what's inside?
Don’t have it; this is one I found at auction for sale.
It looks like the AC plug for an old waffle iron or skillet, so... yeah, no idea at all.
I believe it's a AE (applied Engineering) Ram Keeper.
Damn, son! Look at this guy! You sir, are ON POINT!
Darn good detective work!!
It is, I have one just like this and the dead battery to boot.
