Narrative:
We had a basic 757 (unable RNAV SID; stars; and approaches). Flight plan filed non RNAV SID. Cpdlc said revised segment SID X. Accepted it and called clearance on taxi out and said no RNAV. He said ok and gave us SID Y. Tower said line up and wait and I asked first officer to confirm SID Y with tower. She said no; SID X. I said no; can't do it. Taxied off runway and got SID Y and took off. I do not remember if we were ever cleared for takeoff and it is now considered an aborted takeoff.for months; basic 757s have not been allowed to do RNAV. We file correctly; they change it. We then told them we can't do it; they change it back. Tower then tells us to fly something we told them twice we cannot do. How many times am I expected to change other people's mistakes? This event occurs because computers do what humans used to do. Dispatch files a non RNAV SID and some ATC computer says no one else is doing that; you're not going to either. Why have a navaid strip on the flight plan if no one looks at it? On the way to ZZZ1 we were filed the non RNAV STAR. Twice; we were told to intercept the RNAV STAR. Again; why have a flight plan if no one is going to keep us on it? I suggest a note; email; or heads up from dispatch to ATC to not change routing of these aircraft when they file a flight plan.

Title: B757 Captain reported that ATC assigns RNAV routes to basic B757s that are not allowed to do RNAV.
Narrative: We had a basic 757 (unable RNAV SID; STARs; and approaches). Flight Plan filed non RNAV SID. CPDLC said revised segment SID X. Accepted it and called clearance on taxi out and said NO RNAV. He said OK and gave us SID Y. Tower said Line up and wait and I asked FO to confirm SID Y with Tower. She said no; SID X. I said no; can't do it. Taxied off Runway and got SID Y and took off. I do not remember if we were ever cleared for takeoff and it is now considered an aborted takeoff.For months; basic 757s have not been allowed to do RNAV. We file correctly; they change it.
