No, both of them have 16 Mhz ceramic resonators.


Here's a schematic for the second one.


what are you using to draw those traces on the protoboard?


I used a CircuitWriter. It's a pen that writes with a conductive polymer. It's great for turning perfboard into a psuedo-pcb.


Once you've written a trace with that pen, can you solder onto it (better than soldering onto the bare fiberglass of the protoboard)?  I don't think I'd trust an ink trace, but it might be a handy soldering aid if that works.
