Pratt Tribune Home computers, tablets and other electronic devices are immune to corona virus, but they can have other issues that affect their performance and that’s where Curt Oller says he and staff at Pratt CDS/Radio Shack, 620 North Main Street, are able to come to the rescue. “We can help retrieve data, do repairs and install updates,” said Oller, whose background in electronics dates back to the late 90s when his home-built computer was hacked--an event that set Oller on the path of self-learning about computers from the inside out and to his opening PC Unlimited in the 200 block of Main almost two decades ago, at the current location of N’Cahoots Coffee & Shoppe, where he specialized in both sales and service as he does now through CDS/Radio Shack.
