Casio Collectors

Hi Christian! Welcome aboard this forum - and also the CasioSK group.
I've only recently started this group, so please bear with me while I "stock the larder" here with all sorts of goodies, and any tips, hints and advice that you bring here from your Tablehooters site are most welcome.

Cheers, Graham

Also the various Casio calculator emulators on the internet could be useful to understand what kinds of special CPUs Casio has
