B&W G3 (Rev.1) RAM Slot Mystery - J23?

[Wild Hare]

Received these images (now combined here) of RAM in a Rev.1 B&W G3.


J23 but no J19 or J20? All four slots appear occupied.


Now I have checked a Rev.1 mobo AND a Rev.2 here, for the following:


It’s J19 through J22 RAM slots on both Rev.1 and Rev.2 boards here.

But, one stick not reporting in the first image - AND adding a “J23” slot?

Some “thing” is not quite right. Simple explanation?

The immediate thought that comes to mind is that it could be either the RAM or the slot.

well first things first are you positive the top computer etc is indeed a G3 blue and white, because thats showing a 512MB stick and those dont work with G3 blue and white's at all like that, they will only ever show up as 256MB sticks, so that has me thinking thats gotta be an AGP based G4 of some kind
