GeoCable Interface


The geoCable interface works with Geos printer drivers configured for geoCable, The Write Stuff with a patch (see elsewhere on this site), the ACE15 operating system, and some other programs. The advantage, beside a possible increase in sending data to the printer, is it's cost and ease of use. There are no chips to die and no DIP switches to fiddle with.

The interface is simply a cable between the printer and the User Port.

Either wiring will work for either program, but the geoCable wiring is preferred.
