Edição das 20h36min 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.
Arquivo:PAINEL BANCTEC 91690.PDF
Quando
A idéia é trabalhar no painel durante o evento Eletrônica com Carinho que acontece às segundas-feiras, às 19h 30min.
Histórico de Atividades
Esta página será utilizada para registrar o progresso das atividades.
27/08/2012
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).
