This is one of two kits for converting your typewriter into a USB keyboard. This kit comes with all components and contacts soldered in place -- you need only attach it to your typewriter, following the instructions given at: www.usbtypewriter.com/category/installation-instructions
The only tools you should need to complete this modification are tweezers, pliers, a dremel tool or metal file, and hot glue. The job should take less than an afternoon.
Because the conversion kit I send you needs to fit your typewriter, I may ask you to send photos of your typewriter's undercarriage so that I can size it correctly.
