Title: New owner of a IGT Gameking 3902 V4.0? Questions about swapping games and denom
Post by: Danger86 on January 16, 2023, 11:26:09 PM
Hey all,

I just picked up a Gameking Slant 3902 v4.0 I believe. It's got 27 games on it. Has a 19 inch LCD monitor and MEI Bill acceptor.

I will get a list of all the games tomorrow after work. But it has about 11 poker games, Blackjack, 8 slots, and probably like 7 keno games.
Games that it has for sure:
Black Rhino
Super 8 Line
Diamond Mine
Double Bucks
On the Prowl
Wild Flower
Lion Fish
Super 8 Race
Super keno
Triple Diamond Keno
3, 6, 9 Keno
2, 4, 6 Keno
4 Card Keno
Keno
Top Bottom Keno

Plus a bunch of poker that I will check tomorrow evening and list.

My question would be is it possible to easily remove certain games from the list and add different ones? I don't really care for Keno that much so I wouldn't mind removing a few of them and possibly a couple of the slot games I don't care for to add additional slot games like enchanted unicorn, Used Cars, Tabasco, South Park, Price Check, Munsters, and Double Diamond?

What would I need to do in order to make the swap while keeping the rest of the games that I have? The other thing I would like to do is swap some of the games around to different denominations. From what I've read I believe I'd need a 22 key set to perform that?

Thanks in advance.

No, unfortunately you can't.  You have to change the entire game set out.  3902 I-game software such as you mentioned (used cars, tabasco, etc) are single game software sets.  So if you want to play Tabasco you'd have to remove the Game King 4.0 software set you have and install the Tabasco software set in its place.

Assuming you have a multi-denomination Game King software set yes, you can change the game selection and denominations however you'd like.  You can only have 12 games enabled per denomination though.  You have to key the machine to do it and most Game King 4.0 sets use Key 17.  If you post the numbers from your Base and GME EPROMS we can tell you for sure.

Yes it is a multi denomination unit.

I've heard people mention upgrading to an 044 board. What advantage would that have? Would it allow me to add more games like I had mentioned before?

If not I read something about people buying additional boards to swap in and out?

I will get the chip numbers when I get home tonight

Welcome to the world of Game Kings!

You could swap out all the chips, but the easier way is to buy additional CPU (sometimes called MPU) trays, as you mentioned, for different games and a supply of EEPROMs (they're cheap!) to store the data for all your games.

But be warned: once you start down the multi-game path, forever will it dominate your destiny, consume you it will!

I started with a humble Game King like you — and now I'm up to 16 games!  :rotfl:

Actually, here's a question that I've been wondering about: is the 3902 tray for a slant top the same as for an upright machine?

Here are the pictures of the board etc.
Also two additional questions. Is it ok to just unplug the machine to turn it off? Secondly, after it's been off for a day when I plug it in everything powers on. The monitor stays black though. It responds to touch so you could play a game but the screen is black. If I unplug the machine and plug it back in it powers on and I get the initializing system screen and then it works perfectly. After that if I turn the machine off and back on the screen comes on right away.


Pictures are too big. I'll have to resize them.

Photos have to be under 1MB to post here.

Something is failing in your monitor.  Could be bad caps, or a thermal intermittent semiconductor, or cold (cracked) solder joints..  Often (but not always) caps will show visible signs of failure such as bulging tops or leaking electrolyte.

And some more

Also in regards to something starting to fail on the monitor. Is that repairable or will I just use it until it fails all together and be stuck buying a new monitor? It is a Kortek KT L190A-22(DT)

Believe it is a 19 pin if that matters at all. There are 25 spaces but only 19 have a contact in them.

That's an 044 MPU with a legacy adapter board installed that allows it to run 3902 game software.  Native 044 software is loaded on a flash card.  You can read about the differences here:

https://newlifegames.com/nlg/index.php?topic=880.msg3985#msg3985

You have a 25 pin monitor, it's determined by the number of pin holes, not the actual number that are populated with pins.  Gets confusing sometimes because IGT had 19 and 25 pin monitors, but the 25 pin has 19 pins installed and sometimes people count those and say they have a 19 pin monitor when it's really a 25 pin.

Edit. I just noticed you said it does have a LCD monitor, I was thinking it was a CRT for some reason.  You may have an inverter going bad or the CCFLs may be failing.  The inverter is a fairly common failure item, easy to replace and fairly cheap, I'd try that first.

Your monitor is a 25 pin, it goes by the number of pin holes, not the number of them that are populated.

Thank you for the info. So given that this has an 044 are there any advantages to that vs a standard 3902 mpu or not really being it's got the legacy board on it?

Do you sell the inverter I'd need?

I've had a number of the kortek and tovis monitors that the power supply went out on.  The other things that were mentioned also. Is the led on when the screen is black?.

Thanks,
Wayne

Yes when the screen is black during the initial attempt to power on the little led is green.

They made some improvements to the sound, video resolution, processor, memory etc.  Nothing you'd probably notice playing a regular I-game.  The flash cards have more memory than SIMM cards so they were able to make some better Game King multi-game packages for it.  A favorite of many is Super Star Poker,  It has single hand poker games, multihand poker games (3/5/10play), spin poker, ultimate X poker, super times pay poker, blackjack, keno games, and some I-games including full versions of Coyote Moon and Wolf Run. 

The downside of the 044 is the MPU is expensive compared to a 3902 board and the flash cards are a bit pricey too.  The flash cards are also static sensitive so always ground yourself before handling one and hold it by the edges.

I may have an inverter board for it.  I'd need to see a picture of yours and a part number to know for sure.

I will pull the monitor out tomorrow and get some pictures. I'm assuming I just need to take the back metal cover off to get you what you need to see?

Also looking at some of the 044 topics I think you may have posted this picture of an 044 conversion. If I got rid of the legacy board and put a flashboard could I have this same look with the tabs and those same games?

Sorry to be asking a million questions. Just trying to figure things out. I would have liked to have bought a lot newer machine but this was what I could afford.

Correct on both accounts.  The inverter board is normally a small rectangular board about and inch wide and 5-6 inches long. 

Yes, if you swap the legacy adapter for a flashboard (programmed with the appropriate software) you will have tabbed menus like the one shown (which is a Game King 6.X).  If you go that route make sure to get a developer's bootchip to go with it.  It has built in keychip functions and allows you to skip power up memory tests which will have your machine booting in seconds rather than minutes.

Contact member Sixcardmark, he may still have some flashcards available if you're interested in going that route.

I will try to get the back of the monitor apart this weekend and snap a picture of the inverter board.

Thank you, I will reach out to him. I definitely think I want to go the 6.x route. Looks like more poker games, plus more slots so a win win going that route. Thank you for all the help so far and I'll get the inverter pic posted this weekend.

OK.  Here's PSRs for GK6.4 and Super Star Poker so you can see what each one has game wise.

Here are pictures of the monitor. So originally it would turn on after the second try. Now it's taking 3 tries. Every time the touch works regardless of if the screen is black or not.

This is the inverter board it powers the CCFLs that illuminate the screen.  It looks like someone already replaced the caps and did some other soldering on it as well.  Not the worst soldering job I've seen, but certainly not the best either.  The one connection looks like it could be bridged over to the other pin or close to it.  Someone had display problems to have worked on the board.  I think I have one, but I'll have to look tomorrow to be sure. 

The touchscreen, except being attached to the frame of the monitor and sharing the same 25 pin plug is completely separate from the rest of the monitor.  That's why it works even when the monitor doesn't.

Any luck finding a power inverter to replace this one?

Not yet.  I think they're in my detached garage and it snowed all day, so I hid indoors where it's warm and dry.  I'll venture out there tomorrow and dig around.

Found one!  How about if we do this.  Shoot me a PM with your shipping address and I'll send it to you.  If it fixes your problem then make a small contribution of your choosing to NLG and keep it.  If it doesn't fix it, just box it back up and send it back to me?

Here is the wire with plugs on the end that partially broke when I was swapping out inverter boards.
