Most likely no one DID connect a computer that controls industrial machinery to the internet.

They probably connected a DIFFERENT computer on the same network to the internet.

Apple already "innovated" that size in the Newton back in 1993: https://www.msu.edu/~luckie/gallery/mp100.htm

But I can't figure out the exact size of the screen - all the old articles just show pixel counts.

I haven't tried the OpenRISC cpu but apparently it takes more gates than the MicroBlaze soft-cpu that Xilinx provides. BTW you can already run linux on the Microblaze in many Xilinx devices; see my github repo: https://github.com/jdkoftinoff/mb-linux-msli

Where can I get an OpenRISC CPU and a motherboard that will support it, and how much do they cost compared to Intel/AMD CPUs of similar performance?

OpenRisc is a soft-cpu, defined in the Verilog language, suitable for implementing in many different types of FPGA's of varying price/performance/power.
Here is one source for boards of all types:

• Xilinx Boards and Kits

How much power does the 1.7 Ghz P4 system require vs the Kal-El Quad Core ARM at 1.0 Ghz?

Everything they may replace it with is worse...

Also relevant photos showing the airplane was damaged before impact: missing elevator

Another photo series: impact

Here are some interesting photos which may show that there was mechanical failure: Elevator trim tab missing

You know, all the device needs to do is LOOK like how a dangerous device might look like to an untrained individual. Then the person would wave it around and threaten things. Also, why does it need to be looking like an improvised explosive device? it could be looking like an improvised GPS/Radar/Radio/Cockpit jammer.

Rule #1 in first year engineering courses should be "Don't take your prototype on an airplane"
