A PLC5 chassis has a dedicated slot for the CPU and there is only one of those slots.
I had a go at putting a ControlLogix processor in a PLC5 chassis, and, rather surprisingly, it went in a treat.
Only problem was it wouldn't stand upright to "look the part", as there was a huge distance discrepancy between the card and the guide rails in the chassis. And there was nowhere suitable to plug it into on the backplane, either.
I tried it lying on its side, but that didn't look right either.
I finally settled for it perched at a rather pleasant angle of about 50 deg. from the vertical, gently leaning against an I/O card.
Now I just need some wire and a soldering iron to connect all the controller's pins to the backplane.....

Hmmm... your method seems rather odd to me. But then one does whatever one needs in order to just keep em running. I tried the same my self, but couldn't manage enough room to make all the solder connections. So, I found that several jumper shorting pins across all the backplane pinouts made it such that it wasn't so critical how the processor pins lined up. I actually have ours standing straight up. So far no fault or LEDs have come on! We are good to go.

I wouldn't bother with the soldering iron. Some wet string and gaffer tape works just as well!
