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.
