Hi,
Yup. Still work. But prior to 1950, there were differences in how they worked so one needs to stick a modifying circuit inside or risk the ire of the phone company.
Pencil and paper crash all the time. Rebooting is called sharpening it. I was trying to make a small sketch yesterday and had three pencils bust, and no sharpener in the shop. Ran out of pencils at that point (Ha! Get It?) and had to go to the house for my 'reboots'....
Back in 2010, I was with BlackBerry. Lots of ex-Ericsson folks went there in 2009. Anyway, BB was a Smartphone only outfit. But, we wanted to appeal to the flipphone users. The bosses gave the job to the Ericsson folks as we made more flipphone models than anyone.
So, we made a great one. A tad oversized as we had to incorporate the larger BB keyboard and screen. It sold better than any other model. For six months. Then, zippo sales. Turns out it was a smaller market than we thought. Same thing would happen to anyone who comes out with a 420 or 350 sized crawler today. Thing is, all the crawler makers know this. We didn't.
