My post at http://www.tomshardware.com/forum/50383-28-pressing-mul... got deleted, probably because it was an old thread. Yes, I realize all those contributors from 2004 have likely moved on or don't care anymore or are dead, but guess what? As new people with similar problems are visiting the Internet every day, even as we speak, THEY may care, so I'm reposting my solution, which is:
the MS Sidewinder keyboard for $50 that supports NKRO.
Of course, the old thread, which has been closed, is still a result that comes up in today's Google searches for "pressing multiple keys on keyboard problem" but without my solution, it is now more or less a useless thread. Better if the entire thread were deleted.
So kudos to the moderator who deleted my solution and made this site just a little bit more useless.
