Platform - Computer » ZX Spectrum (Beeper)
ZX Spectrum 16k, ZX Spectrum 48k and ZX Spectrum+
The first ZX Spectrum model was released in 1982.
These early ZX Spectrum models used just primitive bleeper sound which created very noisy output.
"Is there something wrong with this file?" is a typical reaction of casual listener who hears ZX Spectrum beeper music for the first time.
Another cheap feature of early Spectrums were their rubber keyboards
