mr_me, when I start Altirra and have a blue screen, everything types fine. I add the Questron disk, cold reset, questron starts, I click a key to get to the "Enter 1 2 or 3" screen, but then no matter what key I press, it just flashes "press 1 2 or 3" ... but it only flashes when I HIT a key so the input is registering, it's just not doing anything
