I notice that they stopped capitalizing POWER with Power10. I preferred the capitalization since it stands for "Performance Optimization With Enhanced RISC". I wonder whose idea it was to change it.
Capitalisation looks a bit old-fashioned. Memories of LISP, FORTRAN, ALGOL, COBOL, DOS, CICS, IMS, MVS, VM/CMS... Even FORTRAN and LISP are normally Fortran and Lisp nowadays.
2 years ago someone made a GNU/Linux-based Power9 system: https://www.reddit.com/r/linuxmasterrace/comments/x88sdf/my_... Here is a page on making your own: https://www.powerpc-notebook.org/en/
It seems the Power CPUs are still in use.
