UVW-1200

Em 12/SET/2020 eu comprei no Mercado Livre um tocador de videocassete Betamax da SONY, modelo UVW-1200, com o objetivo de estudá-lo e talvez fazer a emulaćão no MAME, em conjunto com o painel de controle SONE PVE-500

Descricao do hardware

A parte eletrônica consiste em 3 PCBs principais e mais algumas PCBs menores:

painel frontal

Possui um display VFD e diversos botoes.
