    Quoted from Freeplay40:

    If you plan on crimping a new connector to the wire, there is no need to be gentle with removing the old connector from the housing. I'm not suggesting a hammer, but all I use is a small screwdriver and press hard on the securing tab....hard enough to simply push it out of the way... then connector comes right out.

    Exactly.

    If you are replacing the contact, just press the locking tab in with an Awl and it slides out with no resistance at all.

    Do this with the connector pulled off of the board/male pins.

    Quoted from westofrome:

    I'm trying to press and slide with the same motion with the tool.

    I only use the tool if I'm keeping the crimped connector end (like someone installed them in the incorrect order).

    Scratch Awl is much faster.

    Poke all the tabs down at once, and slide all the connectors smoothly out.

    Take a pic before you begin just for a sanity check. You can chew up a lot of time having to go back to the schematics.

    Quoted from cody_chunn:

    Which brings up the question: what do you use for a keying pin if you don't have any in your pocket?

    Order a bag of keys whenever you order the housings, because some brands don't fit other brands.

    But if you are totally stuck on location, use your mini diags to cut the old housing down each side, and reuse the old key.

    Quoted from cody_chunn:

    Use 2. Cut one so that put together they have the right number of circuits. Lightly sand the uncut edge and the matching edge of the other connector. Mix a little epoxy and apply a thin coat on both the sanded faces. Stick them together and line them up straight. Let it cure overnight on some cardboard or something. Light pressure on either end is preferred. Wipe off any squeezed-out epoxy with a water damp paper towel. The next day trim off the excess with a box blade.

    I've always had terrible luck getting epoxy to stick to Nylon anything.

    If the old nylon housing is still dimensionally good (it can have a scorch mark, but not deformed), I'll reuse it and simply put the date of rebuilding on the face. Color is a better match than new bright white anyway.

    Quoted from westofrome:

    Do you know specifically which molex connectors are unobtanium?

    The longer ones (like the 20s).

    Sometimes a hoard of them will pop up, but it's iffy.

    Reusing the old nylon housing is sometimes the only solution.

    Remember to date it after you rebuild it, so the next owner does not assume it's 40 years old.....

    Quoted from CNKay:

    Yeah the tool did not seem to work / fit at all. If i am remembering correctly?

    You have to sometimes "do a little circle" with the tool to get it to release.

    Quoted from barakandl:

    they made a lot of early bally ss games

    No doubt, lol.

    =

    But remember, you can simply reuse the old housing.

    No need to throw out a bunch of rare housings when only the contacts need replacing.....
