Trying to find age of manufacture on this Sigma.
Cabinet is 46 high 21 wide.
Any help appreciated
:thank_you:
-
Are there any large or medium sized circuit boards inside? If so post a photo (with good resolution) showing the top of the chips on the circuit board. Can get a ballpark idea of when the machine was built by looking at date codes of the various chips.

does this work excuse the dust
-
From the angle of the photo I can only see a few of the chips clearly that are in the front. But I'd say it was built around 1994. Does that match up with what you were thinking? Are there any stickers or labels anywhere inside, like stuck to some of the sub-assemblies or on the inside cabinet walls of the machine? Sometimes they have dates written on them.
Is knowing the date of mfr critical? (like one of those 25 year old legal concerns)
-
Yes it is a 25 year concern. No other labels etc.
That is the only large board if i disconnected cables and pulled out would that help more?
took a full picture?

The only SG-50 manual we have in the NLG download area has a cover page date of May 1995. I guess it could have been printed after the machines were already being produced, it doesn't have a revision number so it may be the original printing. They would have printed the manual about the same time as the first machines were made, casino techs need the manuals.
I can't see many of the chips on that board but saw some I think with dates of 1994, so the machine wouldn't be older than that, those '94 chips weren't available in 1993 or sooner.
If you can reach in there and wipe some of the dust off and get a higher angle on the photo I could see better. But really, with the 1994 dates I already saw that probably means the machine was made in 1994 or 1995. just my opinion, others where might have more to add about this.
In general we don't worry too much about this 25 year old rule when the machine is this old anyway. Enforcement is pretty lax, you'd have to make someone mad and them raise enough fuss to get the attention of the DA office. Is there a specific worry, like you are going to resell it and need compliance?

was going to list on Craigs list in Maryland

I looked thru the SG-50 manual, toward the back it has a couple of wiring diagrams for the machine. The diagrams are from the Sigma engineering department and have official dates on them. The drawings have dates of late 1994 and early 1995. So I think the machine was made in 1994, possibly 1995.
I'd say it is 25 years old. If it was made in 1994, and you count that as year 1, 2018 is the 25th year.
-
I guess i will wait 2 years. this thing is in great shape everything works
thanks for you r time you have been very helpful and your dates are roughly around what i thought. I got machine in 97-98
-
Hold on-
I'd say it is 25 years old. If it was made in 1994, and you count that as year 1, 2018 is the 25th year.
1994...'95...'96..........2018
..1........2.....3..............25 years existence

Your Math would be hard to argue with what is it on the chips that enabled you to date them?
An actual date or a code?

Most semiconductor companies put a 4 (or 3) digit code on the part that lets you know the year and week (or batch#) the part was made. That helps them to track down bad batches of parts to do recalls. So when you look at the top of a chip you will see its part number and also a date code printed on it. Sometimes they don't do that but on a circuit board with several chips you can usually find enough with date codes to get an idea. The board also has older chips, IGT buys them in large qty so sometimes you will see older date codes, that's normal. What you look for is the newest date codes, that tells you the machine's approx year of being made. Of course someone could swap in a different circuit board so this isn't exact. But lacking stickers with dates or an idplate with the date it's about all we have to use.
That's a good-looking machine - what's it going to sell for there in Maryland?
-
I was thinking $600. Everything works all glass is good I have the keys Thoughts?
BTW thanks again for your time .... these site specific forums never let me down they are a treasure trove of info.

You're welcome! :cool_thumb_up:
Your question about the date of mfr was an interesting one.
We see that machines often do sell for higher prices on the East Coast than in the Midwest. California and Nevada often have good deals for buyers. But final selling price always comes down to how much the buyer wants it and how badly the seller wants to sell. Your price seems fair to me, and you can always accept a counter-offer, which most buyers will try anyway.
Just to make sure you know, we have a Classified Ads section here, but you'd need to become contributing member to list it for sale.
