That is really nice, were you able to get your GFX9000 back in working condition?

Not yet but I'm waiting for some circuits from Spain, we'll know in the coming days.

My GFX9000 has been repaired by changing the whole VRAM and the PEEL chip.

It is a small programmable circuit that responds to I / O requests. In the case of GFX9000 it acts as an interface between MSX and V9990. Here is a generic description:
