The GPO WO162B is a portable tape recorder / player that features a 3,5mm headphone and mic connector. This adds the possibility to use with computers like the Schneider CPC or the Spectrum ZX81 (or similar).
Of course, you can also use it to listen your old tapes - or record to them. It also has a built-in microphone.
It's not pre-owned or used, it is brand new!
It can be powered either with the included power supply or with 4x 1,5V C/LR14 batteries (not included).
