Title: 62-0 Code Comes On Sporadically. Power cycle fixes it -- but why does it show?
Post by: jasonmichael on October 03, 2013, 01:31:56 AM
Anyone ever get this error code -- "Bad Game Prom?"  It comes on about half of the time when I fire up this Triple Diamond machine.  I just power it down and back up and it works fine - and I've been treating it like that for a few months now.  But I'm considering trading/selling the machine and don't want someone to get it and think I screwed them when they power it up and get the 62-0.  Of course, if I can't fix it, I'll tell them about it - but, you know how that can be in the 'negotiations' phase...so...  I checked the repair logs and nothing quite like this existed.  Any thoughts?  Here's a picture of what I'm seeing.

Have you tried re-seating the proms to make sure they are snug with no bent legs. Might just be a bad connection in the socket that way

I have.  I've pulled the chip, cleaned the board with can air duster and re-inserted a couple of times.  The strange thing is the intermittency of the issue.  And to elaborate on that, when I power up and down from a surge protector, the problem arises far less often--maybe 1 in 10 cycles.  When I power up from inside the machine it's a good half the time.

Have you tried chaging the eprom?  It's cheap enough to worth a shot.  Just post what SP chip you have.

Looks like this machine uses an RS style chip, as it is an old S model machine, evidenced by the coin return button to the left of the coin entry.  I would try a replacement RS chip.  Maybe a checksum error in your existing chip.

On the S Model very seldom did changing the Eprom help in a sometimes throws code, usually it was a low battery, they were 3v not 3.6, but more than likely a bad light starter, tube or even light transformer was the culprit, we fought this issue 15 years ago with board traces wrinkled up on the CPU's and they haven't got better I am sure. But if you clean eprom legs, sockets and checked battery then I would first change 3 starters/tubes

Thanks for that info, Jim.  I also have an S Triple Diamond that throws up that same error, but only 1 out of 20 start ups or so.  I was going to change the RS chip, but will try your ideas first.  :-)

Rickhunter:  I have SP0731.  How can I find a replacement?  I'd like to try it.
MVCO:  RS chip?  Sorry, I'm a noob - not sure what that is.  Also, thanks for identifying this machine as an S machine - and not an S Plus.  I always wondered that because it's quite different (set up wise) than the other two machines I have which are S plus machines. 
Blueridgeslots:  You stated that the S machines were 3 volt, not 3.6.  When I bought this machine, it was on a 12 error.  I pulled out the battery which was a 3.6 and put in a replacement 3.6.  I then did a chip reset and it worked fine - except for the occasional 62-0 error I'm posting about here.  Should I change out the battery or will this be OK?  Also, you're talking above my head referencing light starters, tubes or light transformers -- any chance you can elaborate? 
Thanks to you all for your input and help!

Does your processor board attach to the machine like your other S+ machines (that is, it's on a tray with a knob on it, and you lift it out by the knob to disconnect it from the fixed motherboard in the bottom of the machine), or do you have to detach a couple of wire harnesses/molex plugs to disconnect the processor board?

If the processor board is inserted and removed like your other S+ machines, you likely have a very early S+ on your hands.  If it uses molex connectors to connect the wires to the processor board, you have an "S" machine.  S machines typically use a "RSxxxxx" chip, rather than a set of SPxxxx and SSxxxx chips for the game software.

He has an S+ not an S, since he has an SP chip.  You could just post a WTB and any of the dealers who frequent here will offer you one.  I would recommend you get like an SP1271, just so you have the newer one.

Yes - the board is removed just like the S+ board - no special wires or anything. 

Rickhunter:  What's the difference between the chip I have and the SP1271 -- you say "a newer one," but is there any gaming difference?  And what should I reasonably expect to pay for this chip?

Thanks again guys for everything.

Should be able to pick one up for less than $10 I would imagine.  The newer one has separated credit and hopper limits.  That is you can accumulate credits up to 9999 but have your hopper pay out only say 300 coins, and the rest to handpay.  It also counts up the credits faster.  Those are the two big ones, the rest are basically casino back-end.

OK So - with the (continued) generous help of CVslots, I changed out my starters and switched to an SP1271 chip.  And all works well - except, damnit, that 62-0 showed up again last night after a week of being MIA.  Again, just power cycled and it was gone -- but WTH???!

At this point I would consider an mpu board change.  You might have a flakey game prom socket on your board.

OK I'll give that a try today!  Just picked up a new MPU board a few days ago.
