I came across a 1955 advert for one. I cannot find technical details , only
museum exhibits on the web for this early German "Walkman"
Size 1 9/16 x 3 15/16 x 6 11/16 inches , 2 lbs
An amazing 5 hour record time possible with it.
Can anyone direct me to technical details ? I would have thought the LT and
HT batteries and motor of the time would have filled the available space,
and how did the wrist watch microphone work ?
