new user python on hp prime g2, casio cg50

[Liamtoh Resu]

Editing text with the new 20210428 beta connectivity kit seems
to have solved the problem of sending extra characters
along with source code.

I had to install the 20210428 beta on top of the 2020 CK.
The beta software failed to run with an uninstall old software
and then installing the beta.

Clicking on the retro 3.5 disk icon saves the program onto the prime.

The 2020 CK would show a simpler text window with a prompt to save
the program.
