FORTH for the SHARP PC-E500 (S)

RE: FORTH for the SHARP PC-E500 (S)
Now Forth500 is installed on my E500S Smile
I've used the DOS program attached to this post. It's very simple.
In DOSBOX, entering bintoasc forth500.bin creates the ASCII file forth500.txt.
Then forth500.txt can be transferred via serial cable, and loaded with this small BASIC program (here for the expanded version):

10 OPEN "9600,N,8,1,A,C,&1A,N,N" AS #1
20 A=&B0000: INPUT #1,N
30 FOR I=A TO A+N-1

The transfer takes about 7 minutes. I've tried other formats for the ASCII file, but they are slower than this one.

A note on the FT232RL boards: I had two of these boards, but I could invert the signals for only one of the two. The other is certainly a fake.
Since I wanted to make another cable for my PC-G850VS, I bought a third board to the vendor who sold me the good board last year. Unfortunately, this time it was a fake!
The market seems flooded by these fake FTDI chips. They work correctly, but their parameters cannot be changed…
