I found a solution this week. Because I use my Amazon Reward Points for FUN purchases, I checked on Diamond VC500 One Touch Video Capture. I read the reviews because the device was exactly what I need as an amateur...and it would be free with points. All was easy despite the sparse directions; however by trial and error, I got results. [Do not ask how I did it. As I said - trial and error...]
The images show the fuzzy damage of years of playing these tapes, but so does memory.
