Inverted IBM KB-7953
Another old keyboard, this one is the mirror pattern of the last one. For the curious I swapped some of the keycaps around, so this keyboard is white with black details and the other one is black with white details. I've a third one, which is all white. They used to be connected to the IBM pSeries servers at work, and when everything went virtual, rather than just throw them in the bin I took all three. The black one developed a fault and I had to repair it, but otherwise I used them at home for years.
They aren't the best keyboards in the world, but they are a lot better than most, and after I installed some insulating foam in them, they still clunk, but not in as annoying way as previously.
