Hi!
As long as I follow The Ben Heck Show on YT, I hoped for a project concerning the Commodore C64. I was so satisfied to see the Apple I replica and the ZX spectrum projects, but I always wanted to see the Commodore C64 to be benhecked 
My suggestion is a C64 replica (similar to the Apple I) with a 4:3 ratio TFT and a built in VC-1571 5,25" Floppy drive. It should also contain a solution to emulate the Datasette. As alternative an SD2IEC-Adapter is possible, but it would be cool to see a native Commodore Floppy drive in a portable case 
I hope you like my idea.
Bye bye from Germany!
Ingo
