Hah. I still have a Panasonic RX-DS20, purchased around 1990. This is a late-era device, with a CD player in addition to the tape cassette, and digital tuning for radio. It uses 10 D-cell batteries, plus another four AA to store the radio station presets. I didn't carry it around though, it was my home stereo until I was able to afford something bigger. Since it has an aux input, I've continued to use it over the years as computer speakers and such. Rock on!
