Old ATW-1235 Wireless Microphone System

I have an old Audio Technica Wireless system that has been in the closet for years and I was wondering if it still has any use and/or value. It was great when I bought it, but I haven't used a wireless mic for a long time and I'm sure the technology has long moved on.

The system is an ATW-1235 (ATW-R12 Diversity Receiver with an ATM35 High Instensity Cardioid clip on microphone). The box says the frequency is 208.600 mhz, but the the transmitter and receiver say 207.000 mhz.

I found this ad on Reverb.com, but this doesn't doesn't have the clip-on sax mic. (which I guess is the wireless version of this https://www.audio-technica.com/cms/resource_library/literature/ded23fbdf0487654/pro35_submit.pdf)

Any thoughts? I don't know very much about this stuff and just trying to figure out if it I might be able to repurpose it.
