That's a real shame. I first heard of Zuse when I spent a week in class in the Zuse conference room at DEC Spit Brook Road, Nashua aka ZKO1. (there were many rooms in that facility named after computing pioneers...) There were picture

It's important in the historical context of the Alpha AXP to also remember the DEC PRISM architecture. Canceled in 1988. One of many architectures killed off by DEC. https://en.wikipedia.org/wiki/DEC_PRISM Killi

That page does not include VMS DECwindows Motif, so here is a link: https://www.xanthos.se/~joachim/OpenVMS.html VMS DECwindows Motif 1.0 was released in August 1991; it is difficult for me to comprehend that was 35(!)

Only Boulder servers lost sync. To say NIST was off is clickbait hyperbole. This page: https://tf.nist.gov/tf-cgi/servers.cgi shows that NIST has > 16 NTP servers on IPv4, of those, 5 are in Boulder and were affecte

IMHO, "tech optimism" reached its peak in 1969 when Armstrong and Aldrin landed on the Moon. We watched them walk on the Moon on live TV. After seeing them perform that impossible feat, it seemed like we could use technology to do

I still have a PDP-11 Programming Card I bought at that Digital retail store. That was an interesting place. As I recall, there also was a AT&T store in that mall where you could buy... telephones.

This book: https://en.wikipedia.org/wiki/BASIC_Computer_Games I was exposed to this book in about 1975 when I was in detention in the math teacher's room. It set me on a path to programming.

Some businesses are still using DEC PDP-11s, first released in the 1970s. Those are even more "ancient." Many of these are used for industrial controls, among other applications. see: https://news.ycombinator.com&#x2F

Thanks. I'll stick to a walkie-talkie. FRS radios are cheap, easily obtainable, and will work as far or farther than this 915 MHz stuff. If you get into deep shit, some amateur FM handy-talkies are IMHO more likely to be able to get
