I was trying to work out what displays are interchangable and a part of that is what interposers are interchangable.
This is a good picture - essentially showing how similar the 755c and 370c interposers are and how different the 755CE/CX/CD interposers are:
370C at the top
755 CX in the middle
755C at the bottom
Here you can see the 755C and 370C interposers along the top. Despite one connector (for the trackpoint) having a different colour's friction lock, I tried the 370c interposer in a 755c machine and it worked fine.

I decided to see what this weird machine is all about. The HDD had failed so I switched it out to a 2.5" SATA drive and reinstalled Windows XP.
I also installed the video and touchscreen drivers.
I tried to recap the PSU but it was a bit of a mess and decided to leave it alone.
Here are the drivers for the video card and the touchscreen controller.
The machine will take 2 x 1Gb 184-pin 1GB PC2100 266MHz DDR Non-ECC CL2.5 PC RAM for 2Gb total.

I've managed to get a G41 and G50 side-by side. The two main external differences is simply that the G50 has a 'regular' Thinkpad power connector (the larger one) and the LCD is much brighter. The G41 is entirely IBM-branded, whereas the G50 is lid-branded IBM Thinkpad whilst the LCD bezel and base is branded Lenovo. The G50 BIOS has also list the 'IBM' name as well as a few less options...
The biggest difference is that the G41 has a Pentium 4 CPU rated at 3.06Ghz, whilst the G50 has a Celeron M running at 1.6Ghz. Is this the performance hit that it seems like on the surface? I mean maybe a Core 2 Duo at 1.6Mhz, with the right OS might somehow compare to a P4, but a Celeron!? Seems like a massive downgrade. But I don't really know much about comparing the two.. Any comments? I do wonder if I could upgrade the CPU to a Core 2....
I think perhaps both of these machines were actually manufactured by Acer or something like that? Funny how that worked with the transition of IBM IP to Lenovo.
Ideally, I'd like to replace both keyboards with less -shiny ones but they're not exactly common now. The keyboards are the same on the G40, 41 and 50 so you can easily do so.
