ICT printer installed in a S+

[stayouttadabunker]

I totally agree with you guys about the extra coin ...I'm presently shopping for some "Montana" chips

[uniman]

Now , here's the printer in action and I'm showing you an example of what can be printed on thrmal paper!

"Stat's famous Pig in a Bun hotel & casino" 

Thanks for taking the time to document all the work that you did Mark. That is quite an inventive solution. The optical switch continues to talk to the S+ CPU so no other modifications to the slot are needed, and your physical switch sends the pulses to the printer so no electronic ties between the slot and the printer are necessary. It was also clever of you to increase the number of tangs (slots) on the plastic wheel to increase the payout speed.

...
Shouldn't the forth coin count towards the next game?

Only with Montana credits (that would solve your problem stayouttadabunker).
With a normal SP chip any extra coins inserted are returned to the player via the hopper after the spin is concluded. Since his system doesn't change the machine's behavior in any way, he's going to get a ticket for the extra coins. I tested the tolerance once, and I remember that the S Plus will spit out at least five extra coins, but not eight -- I don't recall the exact outcome. If too many extra coins are inserted the machine will produce a coin-in tilt instead of returning the coins. The only time there is enough CPU lag to get that many coins inserted before the reject circuit trips is on that one-in-a-hundred pull when the computer writes to the motherboard.

Stat, I was wondering how you got that many coins (5+) in the machine without the comparitor rejecting them. So if I have it right, you waited until that hundredth spin and then fed them as fast as you could?
Universals both older and newer will take one coin over the max bet and it will be credited to the next game. No way you're going to get that back! LOL 
If by chance two more over make it through the optics the machine tilts. There is no writing to the motherboard (backplane) and so, never a pause.
But there is no montana style credit chips that I know of for the Uni's. Too bad.

I have timed that "writing to motherboard chip" PAUSE...It took a little more than 4-1/2 seconds.
Tommorow I'm gonna see how many coins I can drop in that time frame and report back to ya's!

That's right. I counted the spins so I knew when it was coming. I would have a stack of quarters on their edge ready to go on the coin insert shelf and a few more stacked in my left hand. I have rarely, if ever, experienced a pause of 4¹/₂ seconds. It is usually about 2 - 2¹/₂ seconds and in that time I've managed to get in about 12 extra coins (15 total) before the game came back up and started deflecting them. It might be that every tenth long pause (1000 spins) is longer than normal due to extra data being written. I seem to recall reading something on the old forum about that, but don't quote me.

For regular spins the most I can get in is three coins more than the game takes (six coins for a three-coin game). What's cool about all these tests is that I've never had a coin-in tilt or physical jam no matter how fast I dropped in the coins unless I exceeded the maximum number that the processor could handle during a 1:100 pause: the optics and coin-in sensor are flawless.

With the machine running on "Auto-play", I waited for "The Pause"
Saw it and counted a hundred pulls\plays.
It "paused" lol
I dropped in 10 coins exceptionally quick and they all went in.
Only thing though, I got an error "Code 23".
"Code 23" is transalated to Excessisive Extra Coins In"
"open and close door to clear tilt"...

I took a picture of the reed relay that I bought from Radio Shack used to make this auto-switch.

[stayouttadabunker]

I was looking in the manual and found this molex connector....I'm trying to figure out a couple of things.
Does anyone know what  pin 21 do? I don't know what "(21)PNL DET" means.
Come to think I dont know what "RXD PRINTER(39)", "(87) HP1", "HP2(82)", or "(93)TVD PRINTER" means either.
If anyone might know what these pinouts put out or anything, I may be able to hook up my ICT printer to it instead of the modified hopper.

[Abe Frohman]

Any verdict here? All those pins marked "printer" must be that pulse signal, no?

[stayouttadabunker]

There was never any answer to this...I haven't tried for fear of burning out my ICT printer...
I will be trying more pulse readings from the pins to see what they're outputting...

[stayouttadabunker]

I know this has been a long time Knagl but yes - if the hopper
moves one notch, it prints out a ticket equal to a quarter.
The printer comes with software and all you do is program the
printer to print out whatever denomination you want plus messages.
I know it does graphics as well but they are very
simple and must fit within certain byte parameters.
The printer is fabulous I think and just needs to
be modified to fit a card reader slot really.

Thanks for reviving the post SB

Have not seen these before so did a bit of digging. They have quite a range of products - http://www.ictgroup.com.tw/.
Manuals and software are available on the site. Page 6 describes the pulse interface. Basically it counts the numbers of low pulses. If it stays high for more than 1.5 second it prints the pulse count as a value. Nice and simple interface - good printer to play around with.
