I found the Rev B schematics on the web. It lacks the EPCS drawing
on page 8.

According to
http://forums.parallax.com/showthread.php/132578-Getting-started-with-FPGAs/page7
there are also versions with a 64 Mbit Altera EPCS64.

So my guess is:
  Rev A: EPCS16
  Rev B: Altera EPCS64
  Rev C: Spansian EPCS64

Unless Andrew and I have Rev Fs, as there's no "C" on our boards.

when I'm talking to journalists I just say "programmer" or something like that.
