I am looking for a manual or help with a problem that has started with my joker poker machine. When you deal the cards they come up, but they dont stay there and start dealing themselves. Its like the game is playing and chooses what to discard and won't stop so you can choose. Not sure I there is a wire crossed or a board problem. Any help would be appreciated. It is a 1982 hi-lo joker poker I believe made by greyhound
 
maybe disconnect the wires from the buttons...if they're not wired right it would act like you're pushing the buttons, even if you weren't...
 
I fixed one of these Greyhound Electronics games for a guy last year. It looked like this: http://flyers.arcade-museum.com/?page=flyer&db=videodb&id=4271&image=4

If yours is similar, you might find...

There's a 22/44 edge connector on the PCB. Remove it. It's only used for inputs (buttons, button lights, coin, lockout, and test mode, IIRC). Power and video are on seperate connectors, so it should boot up and show attract mode (but not start a game).

You might try playing it like this... jumper lines to GND (A & 1 on the edge connector). For example, coin is 10 (solder side), the top row of 5 buttons are 15-19 (also solder side), deal cancel & stand are 20, 21 & 22. The last button (Play / Raise?) is C, on the parts side.

If you determine it is a board problem, first take a good close for broken traces, esp on the end of the PCB near the edge connector. There are two 8255 interface-I/O chips on there that go between the buttons and the CPU.

Hopefully you'll determine that the board is fine, and instead you've got connector issues (either the split pins in the edge conn., or one of the molex connectors between it and the housing, or at the quick-disconnects to the buttons).
 
That is different then mine, here is a pic of mine. I have disconnected some of the switch wires and it stills redraws on its own. Is it possible a chip is bad? I mioght have connected a wrong wire to something when i was trying to get the lights to work.

Yeah, the cards look similar. It's likely another Greyhound game, with the same hardware, just running different ROMS than the one I worked on... but I can't be sure.

Does it look like this?: http://softwarethis.com/arcade/boards/reel/pics/reel.jpg (except that board has had one of its chips snipped off...)

It's absolutely possible that an IC is toast; esp if it was hooked up to the 12V (I think) supply for the button lamps. But I'd do a fair amount of checking before going this route; those 8255s aren't very easy to find (for me).

I had several non-working button lights too... fixed them by replacing dead lamps, replacing bad QD connectors, and replacing old split pins in the edge connector.
 
Thanks Darren and Mudhens1,

When I got home I took the board out of my draw poker machine and hooked it up to this machine and it worked fine. I swapped the 8255 and the joker board worked. I put the others in the draw poker and tried it and it worked also. not sure what happened, but i am leaving it alone, they are both working. Thanks for the help from you and Mudhens1 and the quick responses.
 
Mine was doing the same type of thing when I got it. I ended up pushing on the chips on the board, and wiggling stuff around, and it fixed itself.
 
Just did a little searching, based on the title on the bezel of your pic. There's a game emulated in MAME with this exact title, but it's by "SMS Manufacturing," not Greyhound.

There's a sweet ASCII-art drawing of an SMS Mfg. PCB in the MAME source, but it doesn't paste into a forum message for crap. Go to line 2929 here: http://mamedev.org/source/src/mame/drivers/norautp.c.html
It's 8080-based (vice Z80 on Greyhound boards).

Hi-lo joker poker board nuts

Anyone know what I can do to get help with the board. It comes up scrambled, than it come up fine. Lately always scrambled. Anything on the board I can check? Another board works fine. Thanks Ron
