Hi all,
An updated version of the Flex-PCB replacement guide (ver.2) for the HP-41 I/O block is available.
Follow the link in the corresponding page here.
Some hints from a friendly user (thanks Dan) regarding the initial positioning a long with a detailed reference to the "pre-bending" piercing process have been included.
Text font and pics quality have also been improved.
Hope you find it useful.
All the best.
Diego.
