Transporting a portable operating system: UNIX to an IBM minicomputer (1983) [pdf] (sci-hub.se)

The term "transporting" was new to me. I hadn't realized that 'porting was just a shortened version of that, which apparently took over and fully replaced the long version.


Apparently there was a Series/1 in 2016 still running to support US nuclear weapons.

"According to this document, there is still a Series/1 that "Coordinates the operational functions of the United States' nuclear forces, such as intercontinental ballistic missiles, nuclear bombers, and tanker support aircraft." This system still uses 8-inch floppy disks, however the agency plans to update some of the technology by the end of the 2017 fiscal year."

Score another for Sci-hub.

This article is more interesting for the glimpse into the world of the nascent personal computer movement (hijacked for three decades by MS) than for its conclusions about Unix's "trans"-portability.

The deft accommodation of endianness mismatch was eye opening. The world has settled firmly on little-endianess, but there are other similar incompatibilities always lurking, and always needing similar pragmatism.

Perhaps most surprising to me was that they did not lease access to a PDP-11 for long enough to do the port, instead of buying one. I have to guess that they actually really wanted one, anyway.


Is zero.sci-hub.se not loading for anyone else? It's timed out twice for me.

edit: going through Tor I can access it fine. Weird.
