Blake PattersonDid you know that the 'NT' in Windows NT stood for "Nine Ten"? The intended core platform for the OS was the then-expected Intel i910 RISC processor, which was to be the rebranded moniker for the i860 that can be found in the wild. *It never came to be due to the i860s terrible handling of context switching -- a capability that a CPU for a multitasking, multiuser workstation OS must be able to do _very_efficiently_. The i860 wasn't. <a href="https://www.youtube.com/watch?v=WTkFGZqVCM8&t=459s" rel="nofollow noopener" translate="no" target="_blank">https://www.youtube.com/watch?v=WTkFGZqVCM8&t=459s</a>*** EDIT: Several have pointed to sources indicating differently that NT stood for N10, which was the codename for the i860, so -- N10, N-Ten > NT. <a href="https://oldbytes.space/tags/TIL" class="mention hashtag" rel="nofollow noopener" target="_blank">#TIL</a> <a href="https://oldbytes.space/tags/WindowsNT" class="mention hashtag" rel="nofollow noopener" target="_blank">#WindowsNT</a> <a href="https://oldbytes.space/tags/Windows" class="mention hashtag" rel="nofollow noopener" target="_blank">#Windows</a> <a href="https://oldbytes.space/tags/Intel" class="mention hashtag" rel="nofollow noopener" target="_blank">#Intel</a> <a href="https://oldbytes.space/tags/i860" class="mention hashtag" rel="nofollow noopener" target="_blank">#i860</a> <a href="https://oldbytes.space/tags/i910" class="mention hashtag" rel="nofollow noopener" target="_blank">#i910</a> <a href="https://oldbytes.space/tags/vintagecomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#vintagecomputing</a> <a href="https://oldbytes.space/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://oldbytes.space/tags/OS" class="mention hashtag" rel="nofollow noopener" target="_blank">#OS</a> <a href="https://oldbytes.space/tags/techhistory" class="mention hashtag" rel="nofollow noopener" target="_blank">#techhistory</a> <a href="https://oldbytes.space/tags/RISC" class="mention hashtag" rel="nofollow noopener" target="_blank">#RISC</a> <a href="https://oldbytes.space/tags/x86" class="mention hashtag" rel="nofollow noopener" target="_blank">#x86</a> <a href="https://oldbytes.space/tags/processors" class="mention hashtag" rel="nofollow noopener" target="_blank">#processors</a> <a href="https://oldbytes.space/tags/computers" class="mention hashtag" rel="nofollow noopener" target="_blank">#computers</a> <a href="https://oldbytes.space/tags/computinghistory" class="mention hashtag" rel="nofollow noopener" target="_blank">#computinghistory</a> <a href="https://oldbytes.space/tags/Microsoft" class="mention hashtag" rel="nofollow noopener" target="_blank">#Microsoft</a>
