If it has loose bearings in the bottom bracket I'd rather not end up with a big mess to try to get back together before I'm ready to replace it. It's a 500 and the serial number is S675033....
Welcome to the forums. I doubt that anything is original to the frame. Based on the serial number in conjuction with the Tange 900 tubuing decal, this is a would appear to be a circa 1986 model. The RSX crankset dates to the late 1990s, so it's clearly a replacement and the bottom bracket may be too. Get us a pic of it.
Even the fork appears to be a replacement. Full chrome is usually indicative of a replacement. On top of that Unicrown forks were pretty rare in the mid-1980s. Finally, it appears to be a 700C fork while the rear wheel is 27". Given the high proabability of a replacement fork, there's also a good possibility of a crashed and bent frame. I'd be closely inspecting the top in doewn tubes, in the area immediately behind the lugs, for wrinkles in the underside of the tubes and fine cracks in the paint. However, the front wheel does not look abnormally close to the frame, so you may be OK and maybe only the OEM fork was bent.
