RE: Technical problem (OT)

Well, the LED can't work. I was thinking that the pin may be miss-labeled
but no... Pin 5 is signal Ground.

Even if the shield had power isn't the polarity wrong?

Hallo allemaal,


I think I found the reason for my email problems. A bit further you 
see "bit......" and that was "bit baCC ngBB MMed". I think there is 
a porno filter active :)


I had to buy a TI-84 for my son for school. Quite interesting, it 
has a Z80 on board. It has a bit...... USB interface and another 
bit....... 2-line interface. This particular interface can be 
connected to the RS-232, please se:
http://www.ticalc.org/hardware/cables/serial.html
http://www.linkkabel.nl/tutorials/linkkabelmaken/schema.htm
The second site is Dutch but the schematic is more clear IMHO.

Why this email? I'm puzzled, I have no idea how this can work well 
with the LED between the two Grounds. 

If anybody can explain this, please! Thank you!
