    Anybody have any manuals/tips for this prototype board?:

    It appears to have:

    - regulated 5v/1A output
    - V1/V2 = 110VAC?

    On the left side, there's three more connectors and two turn knobs.

    Any help is greatly appreciated! I bought this thing at a flea market for

    Sorry. I also wanted to ask for details on the layout of the breadboard ....

  3. I think it is highly unlikely that the V1/V2 binding posts are 120VAC.
    They are much more likely to be something like +/-15 V DC.

    The knobs and connectors on the side are likely variable positive and
    negative supplies.

    All this can be easily checked with a voltmeter, which you will need
    if you intend to do any work with electronics.

    The long narrow plastic blocks will have two busses running the full
    length - you would use those busses to distribute power and ground
    around the board.

    The horizontal groups of five holes each side of the wide groove will
    be connected together (that is, the five holes to the left of the
    groove are connected, and the five to the right are connected, but
    there is no connection across the groove.)

    You insert an IC so it straddles the groove, with the pins inserted in
    the columns of holes each side of the groove. Then you have four free
    holes connected to each IC pin, where you can insert wire jumpers or
    component leads to build your circuit.

    You should use #22 or 24 solid wire for your jumpers - scrap
    multiconductor telephone or data wire is a good source of suitable
