Wow, thanks Homer J, that was amazing watching the cracks propagate, the spalling from the top rounded edge and the way handle broke up. The spalling would generate very small razor sharp glass particles and everything else broke up into reasonably large chunks. I think it comes down to annealing out the built up stresses in the manufacturing process, probably injection molded these days. It's good material science, how does your product behave under extreme stress conditions, now you can see it on camera. Same applies to ceramics, my dad had a friend renovating an old house, he didn't want to take a ceramic toilet bowl out in one piece because it was too heavy so he hit with a sledge hammer. Big mistake, razor sharp schrapnell everywhere, he was lucky.

One hell of an image sensor, 28um pixel size, 25,600 fps at 1280x800 so thats 26Gpixels/s or 314Gbits/s at 12 bit resolution, RGB444 maybe ?. The camera would make an interesting teardown, how do you get that much data out of a chip ? Apparently been replaced by the v2512 with a lot more memory.

Lots of parallelism. Mike has (had?) this early unit which uses 16 channels of serial data:

A lot of the CPU interconnect buses are now around that bitrate too:
