Microsoft LISP

I've still got a copy of the DOS version of Microsoft MuMath on 5.25" floppies and the manual at my parent's house. Dunno if it's readable. I had a relative at Microsoft who sent me a few things I was interested in back in the 80's, including their C compiler.

You can download the 5.10version here:<p><a href="https:&#x2F;&#x2F;winworldpc.com&#x2F;product&#x2F;microsoft-lisp&#x2F;5x" rel="nofollow">https:&#x2F;&#x2F;winworldpc.com&#x2F;product&#x2F;microsoft-lisp&#x2F;5x</a>

&gt; A LISP interpreter for DOS marketed by the Microsoft Corporation in the 1980&#x27;s<p>I&#x27;m disappointed that it was for DOS. I&#x27;d have excepted a Lisp for Xenix ; )<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Xenix" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Xenix</a>

tl,dr: an interpreter for MS-DOS and CP&#x2F;M from the 1980s, no longer sold.
