Flat ribbon cable for powerbook 160 (Interconnect)

[ther3d0ne]

Hello,

I would like to replace the interconnect ribbon cable between the daughterboard and the logic board in my PowerBook 160, but I don't know what ribbon cable pitch I should use.

The repair method I would like to follow is described in this post: https://68kmla.org/bb/threads/how-to-repair-a-powerbook-140-180-interconnect-cable.46387/



Does anyone know the specifications of the original ribbon cable, particularly the pitch and thickness? Any link to buy it from ?

Thank you.

The correct pitch and thickness is 0.025".
Try this, it's an 80 pin cable but you can peel off 8 to get 72. It is stranded which is what you want.

Thanks @luRaichu for your reply. Another question please : I broke the connector that maintain the ribbon cable in place. is there any hack that can keep it in place ?

I did too. In my case I left it attached by one clip. I don't know what to tell you if you've broken both.
