Image of inside of HP71B HP-IL module

I can't believe that the contacts have been accidentally damaged. It seems to me that they have been deliberately removed. For what purpose? Not to wire the module inside the HP-71B case, as can be done with RAM or ROM, because it would not fit due to the HP-IL connector.
Maybe have they been reused to repair another module.
In the same way, you may try to find a cheap module like a low-value 4K RAM to get replacement contacts. Soldering them in the right position may be tricky.
