Sorry, this took a while to complete.

I as recently looking for a cassette adapter for a TI-95 Procalc. Alas, the CI-7 is very difficult to find. But, I had a old Commodore C2N Datasette (well more than one :) ) and set about to make an adapter so I could use it with my TI-95.

It then occurred to me that this same adapter could be used for many vintage platforms or homebrew computers where you want a tape interface for that 'real' vintage feel. If your tape interface is digital, i.e. 0-5V, it might just work. You know, the feeling of taking 20 minutes to load a program form tape.

Anyhow, I did a video on it, just an overview of the design and construction. In the description is the design files and BOM.
