Quoted from Waxon:
The card that has the relay only lacks things like capacitors and transistors, the one with the two blue capacitors, is perfect, because it has never been modified, it is still in very good condition apart, With the voltmeter I tried and everything is correct
Just because a board looks clean, doesn't mean that it works or that it's plug & play ready.
A voltmeter won't test the operational status of a board. Especially a board that is missing components, like the driver board. You can only call a board "tested" if it has been properly tested on the bench (ie, in a test fixture), or in a game. As it stands, those boards are what most would consider "untested".
As for the driver board, if care wasn't taken in removing the components, there could have been damage done to the traces. Additionally, the fact that components were removed may indicate that there was an as yet undiagnosed problem with the board.
Untested boards, scavenged boards, and boards in unknown states usually fetch less than a fully working and tested board would.
