Very little is known about the origins of the IBM Thinkpad 130. Someone familiar with Thinkpads can smell a rat a mile off. The cheap plastic, the inferior keyboard, the 'multimedia' styling.... Oh my god, you turn it on and you're greated with "BIOS Utility".... aaaarrggghhh it's an Acer!
Yes, for some reason IBM re-badged one of their subbed out iSeries models for Japan - those with plastic that now snaps like a fortune cookie and famed for low reliability and sub-par displays.
IBM referred to it as the ThinkPad i Series 1200/1300.
This tablet is actually some sort of industrial control computer from Japan. Instead of just being a screen to a computer build-in to some kind of machinary, this is an entire 486 computer with it's own hard drive and ports. Originally the screen was vinegarised but impossible to replace - so I de-vinegared it with IPA and managed to find polarisers which were suitable to get a good colour image.
Also doing it without damaging it or the touch controls was no easy feat!
This funny little beast is, as far as I know a Japan-only unit made for sale directly to large corporate customers, possibly as a point of sale device. Mine is a 2435-A01
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
