My very first station was a tiny 500-watt daytimer, playing country and gospel music. Even when I worked there (1990-91), they STILL did not have a CD player yet. Not really that big of a deal for the late afternoon hours when we were dayparted gospel, but almost every day, we were receiving new CDs that we obviously couldn't play. Add to that, it was in March 1991 when the CDXs first started coming out. Record companies discontinued sending out 45s. I left that station that month, so I don't know how they handled it. But a couple of years later when I passed through there, I tuned them in, and they were STILL playing the same handful of songs that they had been playing when I was there a couple of years earlier! So that told me that they STILL did not have a CD player yet, and by this time, it was about 1992 or 1993. So I am guessing that they did not switch over until a few years after that, by which time they were under new ownership.
