Theta Data Transport and Gen 2 dac

I have the above components packed away since the early to mid 90's. Are they worth anything at all, or should I recycle the electronics?
Looks like the pair would sell for $600-800 on eBay judging by recent completed sales. List each separately and see how it goes. Probably not AudioGon material, I see a number of listings via HiFi Shark but not sure how many sold
