Not sure what you mean by 'too small'. The boards have the same number of
header pins ((2x20)x2). You do need to wire up RS232 serial and SDcard to the
DE0-NANO (burning about 8 or so pins) since they are not on the baseboard.
And of course on the smaller board you don't get all the LEDs and switches.
The CycloneII part on the DE1 board has fewer logic elements than does the
CycloneIV part on the DE0-NANO, and has less embedded RAM blocks as well.
His source has configuration files for the DE0-NANO so it is probably just a matter
of recompiling.
For PDP2011 direct compatibility then the path of
least resistance is
probably
the DE0-NANO with CycloneIV for $79. I have several; nice little boards
for experimentation.
You can get it from Adafruit ($99) or Digikey as well. Direct from
Terasic has high shipping cost.
A quick look at the PDP2011 site says that is it is too small
for the optional PDP 11 features.
