Good evening and excuse me for a trivial question.
I wonder if there is a way to feed a real HP67 with a new program, without keystroke, I mean, a program available in TXT or raw format edited via PC
Other than a mag card, no. A genuine '67 has no interface ports, so no way to get the program into the device other than the keyboard and the card reader.

Get a replacement board from Teenix, then you can use Bluetooth! ;)
I recommend those, BTW.

Build a robot to do it. 
Oh, I like this solution, Ian, it can be useful for other heavy work as well
Someone with better 41c experience should chime in on whether this works or not (I have a 41c but none of the needed peripherals):
1. From the PC print a barcode version of the program
2. Read the barcode into the 41c via the optical wand
3. Use the card reader to write a card for the 67
4. Read the card on the -67.
My guesses as to what might not work:
1. Card reader on -41c only reads; doesn’t write
2. Bar code only readable in -41ese; nothing translate back into-67 op codes

While the HP-41C card reader can certainly write to cards, I don't believe it can write instructions that a HP-67 could understand.
From
https://www.hpmuseum.org/hp41.htm, "The HP-41C was obviously not code compatible HP-67, however, a sophisticated translator was built into the card reader which translated programs to HP-41C code on the fly.".
@Steve Simpkin @ [kby]
Thanks for your comments.
I also thought I could solve through the HP41, actually instead of the optical wand through HP-IL, (the result does not change), but it's not possible for the reasons Steve explained, infact if you can read with a -41' reader -67's cards you can't play the same game vice versa ...
I read , after a try
this old post
I wrote two very simple programs on the -41, which on the -67, are not recognized, the card reader requires additional cards (Crd).....
Doing viceversa, I've noticed that the -41 imports the -67's program adding two extra (prefix?) lines: LBL67 and LBL10

Hi Massimo, it seems that these boards solve a lot of problems, a well done job, once more congrat to the authors
