[1000mp] LPT CW Interface

[Alex NE7L]

Hi guys !

I am looking for some computer interface with CW for my radio.

My current setup has simple COM cable for CAT interface. I was pretty 
satisfied with it till I realized that I need CW too.
In my understanding the options we have are:
 - LPT cable (with transistors) to push the PTT and key the radio
 - some fancy boxes like "CW Keyer" or "USB Interface" made by microHAM.
Did I miss anything?

I can buy the microHAM's box and relax, but I am just wandering - is there 
any place where I can get the properly built LPT cable?

What else... radio is plain 1000MP, loggers - TR-LOG and N1MM, computer has 
one LPT port and one COM which is already taken by CAT.

Thanks,
