This. An old netbook cam emulate a PDP10 with ITS, Maclisp and some DECNET-TCP/IP clients and barely suffer any lag...

Also the Amiga's have AmiSSL and it will run on a 68040 or some FPGA with same constraints. IRC over TLS, Gemini, JS-less web, Usenet, EMail... not requiring tons of GB.

Nowadays even the Artemis crew can't properly launch Outlook. If I were the IT manager I'd just set Claws-mail/thunderbird with file attachments, MSMTP+ISYNC as backends (caching and batch sending/receiving emails, you know, high end technology inspired by the 80's) and NNCP to relay packets where cuts in space are granted and thus NNCP can just push packets on demand.

The cost? my Atom n270 junk can run NNCP and it's written in damn Golang. Any user can understand Thunderbird/Claws Mail. They don't need to setup anything, the IT manager would set it all and the mail client would run seamlessly, you know, with a fancy GUI for everything.

Yet we are suffering the 'wonders' of vibe coding and Electron programmers pushing fancy tecnology where the old one would just work as it's tested like crazy.
