Was your friend supposed to meet me to look at an m6805? Just curious. Honestly, I doubt you will find an m68xx series laptop that is in any kind of good condition for $700.
I am trying to sell mine, and have looked as many places as I could to get an accurate idea on price and haven't found one yet in good to excellent condition for less than $750, and that is before shipping.
If you are the guy who was coming along with your buddy, tell him he can have mine for $750. That's my last offer on it. If you are thinking, "who the hell is this guy?", then nevermind, you are the wrong person.
