“Short summary: MS/DOS overtakes Unix after a few months, and then after leading for a few years, it’s Windows Whatever for the rest of time.”
Because MS made deals with all the computer manufacturers to lock all the other Operating Systems out of the industry. And it is STILL like this or Linux would have put them in the dirt long ago if it was a factory option. If it wasn’t locked out, Linux would have screamed past MS when the garbage Win 10 came out.
started out with cp/m, then msdos, all the windows flavors till win-11, Ibm Risc-6000 Unix, now Linux Mint. Been at this since the mid 70’s. Hardware wise old IBM System-3’s then midrange mini’s both DEC & IBM, all PC flavors. Now decades later using an old bastardized PC with intel motherboard running linux and happy as a clam with it. Regression at its best lol.
