I came into possession of a couple of TI-74 basicalcs a little while ago with a printer attachement and a couple of ROM cards with some kind of tax software on them.
They're pretty cool little devices. Kind of frustrating to program on though. I wouldn't have wanted to have to do that for a living. But still pretty cool to have something with that kind of power you can carry in a large pocket in 1985.

another chip from TMS 7000 family also reported)[2]
