Hi. Nicely done ! Interesting video and beautiful collection you got there. I bought the MZ-N10 and the MZ-E900 back in the days (23 years ago more or less). Both are awesome pieces of tech. I also bought a Minidisc deck : MDS-JE480 and still enjoy it in my living room. I recently had to replace both the batteries on the portable units and, now they just work like they're brand new ! I still enjoy my collection of MD on an every day basis. Did you replace the battery of your MZ-N10 while you were at it ? Anyway thanks for the upload.
