How to build an extra Midi Port

Article from: citizen smith <mbdk98@dial.pipex.com>

Here it is the description to build an extra Midi port
It's dead simple and it won't even invalidate your waranty ;-/
You'll be able to get the parts at tandys or somewhere. I haven't done this yet but aparently the bloke from the magasine got it working (danny mcaleer of "the mix")

Pinout for midi plug:

3     1
 5   4
   2

Pinout for modem port:

1  2  3  4  5  6  7  8  9 10 11 12 13
 14 15 16 17 18 19 20 21 22 23 24 25

(both external port veiw)

You'll need a female 25pin modem conector and a female midi plug as seen above (badly done i know) and 2 220 ohm resistors (this seems to be an arbitary value however..) and some wire....

Connect one resistor between Pin 2 on the modem and Pin 4 on the Midi and another between Pin 7 on the modem and Pin 5 on midi, finally concet a bit of wire between Pin 7 modem and Pin 2 midi.

Thats it !( for the hardware anyway)
Now you need to get the export.drv file from one of steinbergs websites or from the place that makes the noboxe expander who strangely have a more recent version at:

• Expander
   

Toasted your atari?
Your problem..you knew the risks. Don't sue me. $-[
