I'm not not Mark, but you can download the Cardo font from the following site: http://www.scholarsfonts.net/cardofnt.html
Thanks for all the answers. I should have looked in BHS, but as I am used in using Bible Works, I don't look much in the print-version anymore ;-) I am not familiair to working with unicode fonts (I use the bibleworks font most of the time). Can I just install cardo (or the like), type the ID516 code en press ALT+X?
If you only need an occasional Greek character, then that works fine. (But it's 1D516 not ID516.) If you need to do more typing in Greek/Hebrew, then you really need to install Unicode keyboards or get Tavultesoft's Keyman or use an online "Greek inputter" or Logos' Shibboleth or check here.
