Edição das 20h53min de 26 de setembro de 2012

O Garoa recebeu como doação o Painel de operação de uma classificadora de cheques, marca Banctec modelo 91690, que foi aposentada em 2011.

Pretendemos reutilizar o Painel no Garoa e para isso vamos fazer engenharia reversa no equipamento.

O Painel

É composto por um display de 7 linhas por 40 colunas, com dois botões (FEED, STOP) e um teclado numérico com algumas teclas adicionais (A,B,C,D,E,F,DO,CHG,CLR,EX).

Documentação

Temos também boa parte da documentação de manutenção da máquina na qual o painel era utilizado. Documentação do Painel Banctec 91690

Quando

A idéia é trabalhar no painel durante o evento Eletrônica com Carinho que acontece às segundas-feiras, às 19h 30min.

Documentação

Documentação do equipamento: Arquivo:PAINEL BANCTEC 91690.PDF

Fotos (ToDo)

O painel foi desmontado e tiramos fotos de todas as placas.

Revisamos a documentação e localizamos o esquemático das placas que compõem o painel.

Próximo passo: Fazer dump da EPROM para tentar entender como o painel processa e exibe os dados.

06/Set/2012

Tentando descobrir qual o modelo de EPROM usado.

Documentação menciona TTL PROM 2048 x8. Etiqueta do que parece ser a EPROM tem escrito o código 0111-004.

No esquemático o chip está identificado como dm87s191

Dump da EPROM efetuado

Foram utilizados dois CI SN74393N - Dual 4-bit counter para passar os endereços para a EPROM (11 bits) e um arduino para ler os dados (8 bits por endereço).
