Hacking a typewriter into a teletype

I think they did. I have a 'typewriter' somewhere that's a wide-carriage version of that little Alps 4-colour plotter (you know, the one that everybody used in the mid 1980s -- Tandy CGP115, Commodore 1520, etc). It has a Centronice posrt on the side and takes the same commands as said plotters. I also haev a little box in my pile of oddments that cotnains a microcontroller, has a Cntronics socket on one side and a ribbob cable ending in an adge connector coming out of it). On top is a swtich marked something like 'typewirter/computer' I assume it's an interface for some modle of electornic typewriter to turn it into a printer. I am not so sure. I would have thought you didn't want too much intellegence i nthe machine to get in the way. -tony
