I'm sure many (most?) K programs fit in 75 KB, even if the runtime 
itself is another 200.

Tiny wikis seem to be around 8-10K.  (could TiddlyWiki be stripped down 
to 75?)

On Mac OS/X, not known for being svelte, as is 24K, dc 40K, ed 56K, and 
mpeg and zip 72K.

http://www.tinyapps.org/ puts the "tiny" line at 1.44 MB, but lists 
several sub-75K programs -- most notably the original VisiCalc, 
weighing in at 27K.

It seems there really was a Mel, The Programmer:
   http://www.wps.com/projects/LGP-21/mel-the-programmer.html

and maybe the reason that 'dc' is capable of general computations is 
that, for those who were around at the time, a "desk calculator" was 
not a $2 10-key job that sits on one's desk, but instead an 800-pound 
device that one sat at, like a desk.
