For some reason, i believe in a really old issue of nintedo power, was a ad for "office boy".
If my memory is recalling the ad properly, it basically was like a word processor / calculator on a GB cart, and had a minuscule keyboard that hooked up to the gameboys ext. port.
....... Or am i just crazy? I found it in a old issue of NP laying around the public library. Please tell me someone else knows what i am talking about!
[And if you do know what i am talking about, and happen to have that issue of NP, would someone mind posting a shot of the ad?]
That sounds like the "Work Boy".
