Thanks, but it's not a great accomplishment. I've used the document I posted here.
I used an FTDI board instead of a cable. As you can see in the picture, my solution is certainly not the most elegant, but it cost me almost nothing.

At first, I was even more confused!
HMMHEX.TXT is not uuencoded! It's an ASCII file containing a list of hex codes, and written in a special format.
The loader just reads the hex codes, converts them to numeric values, and POKEs these values into memory at the desired addresses.
But that could be a solution. I guess it would not be very difficult to write a program that converts the binary file to a similar ASCII file, in order to use this kind of loader.
I'll have to think about that.

There are still some things I don't understand very well.
What's the meaning of OPEN "1200"AS #1 ? I don't understand the "1200". Does it mean port COM?
And I didn't know the LOADM instruction. Even if I guess what it does, it is not in the manual…
