A while ago, I found a website dealing with MK14 things at
http://members.aol.com/mk14emu/

It includes a copy of of the PE review.

  I have a working example of the inexpensive board
national sold with that
 chip, 256bytes of ram and a monitor.

 I'd doubt there is a site with a data sheet unless someone got permission
 form National Semi to scan one. 
The Introkit and the MK14 are very similar.  The site I mentioned above has
part of the SC/MP data sheet, the MK14 circuit diagram and parts lists, and
programing information.  Now all I need is the SC/MP chip.

Related topic: has anyone here come across a small micro called a Scrumpi,
based ob the SC/MP?
