In Bad English ( tranlate By Sofware from Portuguese- Brazilian )

See how I solved the problem of Hardware (Tape recorder)

As I detected that the problem was the bus A15 of Eprom 27c801, that it represented the address exactly (08000 Hexa).
Then I followed the pin A15 in the Tape recorder's circuit and I arrived to the transistor Q7P, then with multimeter I saw that it was totally altered in relation to the other ones, then as rarely use some chip of 48 pins removed a trasnsitor of the first pin of the connector, and I put in the place of Q7P that was burned, and RESOLVED;:):):)

Em Razoável portugues ( Brasil ) hehehehe!

Veja como resolvi o problema de Hardware ( Gravador )

Como detectei que o defeito era o barramento A15 do Eprom 27c801, que representava justamente o endereço ( 08000 Hexa ).
Então segui o pino A15 no circuito do Gravador e cheguei ao transistor Q7P, então com multimetro vi que estava totalmente alterado em relação aos outros, então como raramento uso algum chip de 48 pinos retirei um trasnsitor do primeiro pino do conector, e coloquei no lugar do Q7P que estava queimado, e RESOLVIDO ;:):):)

Veja a foto da placa dele abaixo.
