I've plugged the VM2 in such a white
testboard where you can build
small electronics simply by putting wires in holes. (Don't know how
they are called in english, sorry).
In my experience, "solderless breadboard" is the usual term, at least
if you're talking about the things I suspect you are. Occasionally a
brand name gets used to refer to them.
'Eurobreadboard' being one that was commnly used over here. i have no
idea if they're still being made.
The other common term is 'plugblock'.
Those who've had problems due to poor contacts or stray capacitance in
these things have various other names for them which can't be repeated on
a familiy list ;-)
