I have a Tascam SX that has OS 1.52 installed. The machine has the Antares and TC stuff SX-1s are known for. I don’t have the OS CD. I called Tascam parts in California. The girl in parts argued with me and said they don’t have 1.52 version OS for SX-1. I gave her my credit card number hoping she would find the 1.52 I’m calling for. She emailed me saying she’s sending me OS 1.50. Does anyone know where I can get version 1.52 OS for SX-1? Thank you. Hubert
