Saucey’s Thoughts

Came across one of these at when I had an electronic recycling job in San Diego (2015-18). Someone dropped it off and I don’t think it came with a hard drive or but I think it turned on. Think we sold it for $100 plus shipping, so $50 on top of that. Didn’t archive those photos… sorry.
