Saving Sharp PC-G850VS text file to tape?

[toml_12953]

I have a Sharp PC-G850VS and I'd like to save C text files to tape. Right now, the only way I can think of doing it is to convert the text file to a BASIC program and BSAVE it. When I want it back, I BLOAD it then convert the BASIC program back to a text file. The problem with this is that BASIC converts everything to upper case and the C interpreter needs lowercase keywords and function names. Is there a better way? I looked all through the English translation of the German translation of the Japanese manual but didn't find anything.

Do you have a USB to RS232C interface ?

Maybe easier to save different types of files than on a cassette ?

That kind of interface looks not too difficult to make DIY.
I am on the process to make one for a PC E500 (15 Pins 1.27mm pitch interface) and one for the PC G850 using a 11 pins 2.54mm pitch interface.
Once validated, i could share the PCB design.

Thanks to both of you for these references. I've built an 11-pin interface for the G850, so it's nice to see a detailed writeup on how to use. The SD gadget would be fun to replicate with some other board as controller.

The "Temporarily Out Of Stock" notice is fairly common these days, so I thought I would do a build from what I have on hand. The Teensy 3.5 has an SD connector on board and is 5V tolerant. Just need to find a display in the parts box!

Thanks for the GitHub link to a SD card gadget !

Found those "HowTo" too that might be interesting to some :
