Tired of bent pins, I'm considering adding ZIF piggyback sockets to my game and reel chip sockets on my S+ board.  Anyone have any recommendations on whether I should or shouldn't do this?  I've found 28 pin Standard ZIF sockets for $4.50 at futurelec here: http://www.futurlec.com/SockZIF.shtml
Is that what I want?  JR

JR,
There's another thread that's been going that'll give you all the answers you're looking for on ZIF's.
Type in ZIF on the search box on top of the page....you'll see the latest stuff....

JR -  I was going to do the exact same thing.  There were a few issues that I came across:  The futurlec model you were looking at is longer than the current socket and will interfere with the jumper that's in front of it.   If you can stomach bending the jumper down there is a second issue:   It makes the socket much higher and you run the risk of hitting the back of the cabinet.  The third:  the pins on the ZIF are not that long and the socket sometimes falls out so other members crazy glue it in.

Those three things are pointing me in the direction of a proper IC extractor for easy "in and out"

Think I'll get an extractor, the one without the big red X.  Anyone have a used one for sale?

yeah the one in radio shack is no good too.   The item that "looks" like it just puts the chip in.  It doesn't take it out.

I have one of my S+ boards using the low profile zifs. They work great. My only gripe is the cost.
I have 3 S+'s and 6 boards. The boards I picked up on Flea bay for $19.99each and I think the two zifs were 26.00 with shipping (within the US).
I was not too concerned about ruining a board since I paid so little for it.

I used a dot of model Airplane glue at the end of a toothpick at each end. My rationalle is that if I needed to remove the zif socket I would still be able to get a jewlers screwdriver between the two sockets and pry.
The model plane glue doesn't have the strength of the superglue. I have not had any problems with it falling off nor interfering.

I would like to get zifs for all of my boards but its on my want-2-dos rather than my need-2-dos. I keep thinking someone is going to find a super deal on these and I can get the cheap some day.

Just to be clear My Need-2-dos fall somewhere lower than my Honey-dos and higher than my should-dos and want-2-dos.

Don't be scared guys!
There's differences between boards...you just gotta check and see what you have is all!
Check out these photos...you'll see the differences between the 10MHz and the 16MHz boards and where the ZIF sockets will go into.
You'll see the jumpers are on the very corners of where the ZIF would be placed.
The board with the big green ZIF socket is on a 10MHz board which had the jumpers soldered toegether with a small wire>>

Finally, the 10MHz board with the big green ZIF socket installed and the jumpers soldered together underneath the ZIF>>

Looks like I have a 10 MHZ board.  Guess I'll just keep using my trusty old steak knife and forget the Zif $$$ocket$.  Should I upgrade to a 16MHZ board?  Pros/cons?

Pros - Faster especially in counting credits.
       - Sound adjustment within the self test (no wheel)

Cons - Limited number of game chips available (Ie no tournament chips, no older 731, some special game chips for themes I dont have).
        - Irritating buzzing noise

         *** The 731 supports the alternate songs for games like 4th of Jully and Bulls eye.

Question: Could you not just put the ziff in backwards...... and mark it with a sharpie indicating which way the chip goes ?

Finally, if you have a board WITH the jumpers, no problem...
there's plenty of room...look carefully and you'll the jumper covers are actually thinner
than the board sockets.
Any ZIF socket (Green, blue,black,white with pink polka dots?) will defintely clear the bent down jumpers! yes
The jumpers are nothing more than 3 wires sticking straight up from outta da board...there's absolutely no harm if you bend them down with the jumper cover flat against the board.
Look closely, on the reel prom , one unused jumper pin is sticking straight up! (no need to bend that one)
On the game prom, bend all three pins down flat...
 Sometimes there's a little yellow resistor like one one in front of that game socket in the second pic.
Again, no harm if you bend it flat down...

Okay, I'm getting the nerve to actually switch games, as soon as I get a kit. Here's my questions: I have one of the green block looking ZIF sockets. If your board is a 10MHz, can a 16MHz chip be used and vise versa?  I just checked mine and it's a 10MHz. I see from the photos that the reel chip says 16MHz. Thanks!!

Duhhh?? If I'm right, your board is a 10MHz with a 16MHz reel chip. I may have answered that question myself, but nonetheless, is that what I'm seeing??

Also, does the board actually need to be compleatly taken out of the machine for a chip change?

Yes, a faster chip can be used in a slower board, but not visa versa.
The 10mhz board is prefered by most, if not all.


Does the board actually need to be compleatly taken out of the machine for a chip change?

Um,,,,,, how else do you plan to change chips? Scratch Head Scratch Head Scratch Head Scratch Head Scratch Head

Yes,
There's absolutely no other way possible....
unless you cut a hole thru 3/16" thick steel and install a door on the back of your machine.... Tongue Out
If your machine is against the wall, you'd have to cut a hole in the wall too and
install the chip from the backyard of your house...I could go on and on but,
 my fingers are missing the keys from laughing as I'm typing... rotflmao bust gut laughing 
(sorry, I'm just kidding)
Pull out the hopper a couple of inches, reach in and grab the black knob and wiggle the knob upwards, guide the whole silver tray over the hopper and out of the machine....if you're strong, take the hopper out first and try not to spill all the quarters on the floor.

Hey guys, everyone started somewhere.  As stated the main board just lifts out, takes no time at all.  see pic.

You're right a69mopar,
I lost my britches there for a moment...
remember, please 5Aces, don't remove or insert the board while the power is on...
Once you have the board out, place it on a good bench and carefully study it it...you'll be amazed what all that stuff does esp. when you have a board schematics laid out in front of you...if you really want to get into it, try to learn what each component does. You'll soon have a super understanding of how a slot machine works!

The low profile from Jameco might be a better way to go.  Appears that it may clear the select pins ???

Mount it backwards so it clears the small yellow cap.

Not cheap though, $7.65 each or 5.44 in quanty greater than 10.

Ok, I've seen this subjet being bandied about several times, and it's prompted me to get off my butt and pull the board out of the S+ to show you all how it's done. Tongue Out Tongue Out Tongue Out rotflmao rotflmao

This is with the Jameco Low-pro ZIF sockets. You'll notice how one has to be rotated 180 degrees from the other one to clear the jumper. Other than that, it's a slam-dunk addition.

LOL!! I should have asked that question a little bit different! What I ment was after the board is out, do you have to diconnect any wires/harness after it's lifted out of the back, or does it connect through PCI type plugs? After I read my own question I split my britches too! bust gut laughing

Okay, I now see how it's done!! I finally got the guts and pulled out the hopper and then the board. I always thought that big metal cover just came off and then the chips and board were just sitting behind it. But everyting is one big piece, board, cover and all. That's cool!! Now I see why you can take everything out and change the chip on your kitchen table. Whew!! I thought I was going to have to do the hole cut in the back of the machine like stayouttadabunker suggested!! bust gut laughing

True, very true!! As you tinker with these things, you start to see how everything is built to be fixed on the spot. It's amazing how everything just comes out and very little is needed to actually change or fix something inside the machine. It makes sense though, being that a broke machine won't make money for the casino and fixing it on the spot get's it back up in no time. If it were only as easy to do this with every other electronic device!! WOW!!

Now you need to bend a small flat screwdriver to use to take out the eproms.
