Dear Mr. Feldman, I ran across the classic computer dialog searching for what became of Otrona Advanced Systems. Tony, who wrote the message, appears sure that Otrona had gone out of business. Can we ask him when Otrona went out of business? I study private companies and their histories and this is an important early one. I would be most grateful for even an approximate shut down date.
