HP-41CX - Time Module?

[anetzer]

Hi there,

So I bought a HP-41CX (Srl 2514S40570) with two broken posts.

I had the vague notion, I would find a time module somewhere in the machine. Possibly, because a hack from the eighties still lurked in some dusty attic of my skull:

Installing modules inside HP-41

When I opened it I found out that clearly the Time Module is integrated into the logic board. There's a quartz crystal soldered directly to the main logic board. Diego, on his Clonix page, refers to the motherboard which I found:



I was not sure what to expect when I bought the CX, but I have seen at least one reference to a separate timer board in another thread here:

[HP-41CL] Time Module Implant

Should I be able to salvage another CX, is there any way to know beforehand, whether I'll find a separate timer board or is it necessary to open the calculator?

Thanks,
