yeah, that would be great. i wear my dot matrix mkI/II almost daily, but it wasn't me in mesa altho' i do visit starbucks around scottsdale. have never seen another in the wild, either mkI/II or IV. right now i am in maui, hi. with my trusty mk I/II. i really like this one since the digits are larger for my old eyes. also that was one of the ones that gave me the biggest challenge to get operating. be back in scotts in sept. peter
