Bernhart...I'll dig up the pics on the ribbon cable and post it.
As far as the clamshell construction....it was a poor choice IMHO, for HP to use this construction. Before you reassemble the IC's into the clamshell use DEOXIT GOLD to coat the pads of the pc board where the ICs leads contact. One of the challenges is the coplanarity of the IC leads. If one lead gets "lifted" or isn't coplanar with the rest of the leads, you'll have a lead that isn't in contact with the pc board and then your HP-34 won't be electrically functional.
