Buena idea!

Yo empecé en septiembre. Ya consegui casi todos los materiales (despues pongo la lista!) y calculo que todo el proyecto (placa madre, componentes, placa del bus con 8 slots) no puede salir mas de unos 500 mangos.

Es un monton de billetes, sobre todo por que podes comprar una hecha por la tercera parte, pero.....tiene otro gustito.

Saludos!

Saludos!

Hola Ariel, seguramente ya lo sabes esto... pero hay un manual de IBM de la XT que tiene el esquema del mother. Seguro te va a ayudar para tu proyecto. El manual se llama "IBM 5160 Technical Reference". Saludos!

dejo el link por si las moscas

LINK

Gracias a ambos!
Temgo impresa incluso la parte de los circuitos de ese libro. Es excelente. Explica TODO lo que hace falta saber

Impresionante laburo Ariel! Aca tenes uno mas que la va a armar...

Hola!
Lista la cara top!   

Así quedó:





Y así está en este momento la cara bottom:





Así se ven ambas:





La "hoja de ruta" que me he propuesto es la siguiente:

1) Terminar y revisar el diseño (Marzo/2013)
2) Hacer un PCB (Abril/2013)
3) Montarlo, cruzar los dedos y ver que ande (Mayo/Junio)

Cuando haya otro avance lo posteo.

Saludos!

Esta quedando imprecionante!

Va zafando,no?
Hable con el de los PCB. "HOY" no puede hacer la placa, por que el sistema que tiene montado para dos caras con agujeros metalizados no le da el tamaño. Pero en un mes o asi lo soluciona, y estima que cada placa puede costar (haciendo 10) unos 200 mangos.

La placa mide mas o menos 30x12 cm.

Se ve muy bien!
