Hi!

Here is the circuit!

(http://www.borg.com/~jglatt/hardware/pc_intfc.htm)

The 6N138 and the PC-900 are possible substitutes for the CNY17.

You can find such circuits by searching at google.

The circuit is so simple you can put it inside the plastic cover of the D-15 connector. I suggest using breadboard to avoid short-circuits!

shouldn’t it be a cny172 optocoupler? :-/

You can find another one here:

They are pretty much the same, this one has added an extra midi-out and midi-thru. I´ve used this one for quite a while now, and it works great!
