Dear all,

I have received this HP71 which I knew was for spare only

so I'm not complaining because it doesn't work.


However, I have just opened it, and based on the service manual

I was expecting to find a flex cable joining the two halves.





A closer look :





The flex is obviously missing, and looks like it was soldered

What do you suggest ?

Does anyone has an actual photo of how it should look ?


Thanks everybody in advance !

Take care Alberto

Ciao Alberto,

I think Etienne Victoria can answer this better than me:

Why not take a section of ribbon cable such as PC's used for the IDE or floppy drives, cut a short section 17 conductors wide, separate the wires slightly at each end, then solder this similar to how Etienne did. I little neater, perhaps.

Hello all,

I agree, it would be much neater.

However, for this particular Hp-71B, I wanted to be able to route the wires separately inside the case.

Also, a folded 17 conductors-wide section would have had an excessive overall thickness IMHO.

I have replaced the flex connector in an HP71 using a bunch of wire-wrap wire in a similar way to Etienne. If the wire is kept together with a few small ties (also wire-wrap wire) it can be very tidy.
