USB interface for old Casio calculators ======================================= This is just a reminder that such thing do exist and is probably available for sale: [1]. If works with the Casio PB-100 so it also work with my FX-700P. Too bad that Soviet comrades did not copy the interface for their Elektronika MK-85 (actually, they planned to do something like that but finally did not include in in the final product due to problems with peripherals). The guy named Manfred Becker have designed the interface and even has some nice pictures on Flickr [2]. And it seems that it should has on Apple computers, too.
