[CQ-Contest] Ic 706 Mark 11 and Writelog for NAQP CW

[N7MAL]

I have a fairly modern day computer, 3.1ghz w/1024 ram running XP. I have 
absolutely no cw keying problems. I still have the original serial adapter I 
built in the late 80's and it works just fine but I don't use it anymore. I 
use CT for contesting and it keys through the LPT1 port. For day-to-day 
DX'ing I use CW Type for CW operation though LPT1.  I bought the LPT port 
adapter years ago from some W1(I think).  Over the years I've had 2 Icom 
rigs and now the MKV. I use the serial port for rig control. I do have beads 
on every cable in/out of my computer(It makes me feel warm/fuzzie).

  I still have an old  486 with windows 3.1 and it does just fine with 
keying
  NA and the LPT port.

  I'm using for everyday and current use N1MM . a Compaq  3400+ AMD  with 
512
  ram and strait out of Lpt with single transistor ckt that I can take out 
and
  use on the  old 486 box and can't hear any differance in the keyed CW,
  however I am not an probably never will be one of the 50 WPMers.
