I know it is a long shoot !
The IBM 6715 / Actionwriter was one of the last daizy wheel typewriter made by
( said to be made to last at least half century, German design ;-) )
It has "kind" of a RS232 port on the back,
I was unable to find any information on this port which was intended to support
two "extremely rare" !!! IBM options
one beeing a REAL RS232 port, the other some kind of display of the two last
I wonder if someone has even connected this typewriter to a computer.
It would be fun to use it like a "modern" TTY
but I think the problem is probably that this typewriter expect a "lot of" (??)
proprietary commands to set
type spacing, margins, baud rate etc ....
Any advice ?? Any help ??
