Re: Permanently broken sdcard

"I broke a card reader a week or so ago, but that was through the medium of coffee (Splash pop fzz) rather than anything else." I seem to remember in the 80's TI or Tandy claiming there was nothing you could put into the keyboard that would permanently damage there computers. I begged to differ poin...
