How to use IGT S+ game kits in an IGT S2000

(Information gathered from this thread, with kudos to Brianzz, Buzz, coorslight115, Foster, Ohio Gaming, r273, StatFreak, and stayouttadabunker for providing valuable information and pictures to make this post possible.)

Most any typical S+ game kit and chips can be used in an S2000 (except for tournament chips). In order to use your S+ kit in an S2000 game, you'll need:

- S2000 base chip SB001000

- Your S+ glass, reel strips, and SS chip

Note: there may be a speed limitation in that SS EPROMs that are not fast enough may cause problems with proper operation in an S2000 machine. No permanent damage will occur, but the game may not behave correctly or could potentially lock up if too slow of a chip is used.

A 27C64 at 120ns (or faster) will work with older S2000 GMEs that are 4 meg.

A 27C64 at 100ns (or faster) will work with newer S2000 GMEs that are 8 meg.

For the older 4MB GMEs, that means the number must be 120 or less (since 1 nanosecond is faster than 2 nanoseconds. 90 nanoseconds is faster than 120 nanoseconds). To determine the chip speed, look at the markings on the chip (under the paper label) -- the last part of the number is the speed. For example, 27c64 120 would be 120ns. 27c64 100 would be 100ns. 27c64 200 would be 200ns (and likely too slow to use, although some members have reported success using 200ns SS chips).

Warning: ALWAYS ensure that the machine power is OFF when removing or inserting the MPU board.

Install the SB001000 chip in the U21 socket, and the SS chip in U17 (see pictures below).

Note: The SS chip has fewer pins than the U17 socket. Install the chip ensuring that the notch in the chip is in the same direction as the notch in the socket, but leave a gap between the notches (the chip should be up against the un-notched end of the socket). See the diagram below for a visual look at how the chip should be installed in the socket.

You cannot change the payback percentage through the S2000 menus for S+ games used in an S2000 -- the payback is determined by the data on the SS chip (just as it is with a S+ machine).

You may have to do a clear and/or keychip to change key menu settings including the accounting denomination. Use Keychip 17 to access keychip functions.

The S2000 will take advantage of the backlit reels (if equipped), however S+ reel strips are slightly wider than S2000 backlit strips. You may wish to consider using S2000 non-backlit reels with your S+ strips to avoid having to cut the strips down to fit in the backlit reel baskets (S2000 non-backlit reel baskets are slightly wider than their backlit cousins, and are the same width as S+ reel baskets).

The S2000 will also give you more advanced sound than the S+, however specialty games with respin sounds (Spin 'Til You Win, Coral Reef, Bullseye, etc.) will not have different song selections available like they would on a S+ machine with an older SP chip -- it will just play "We're in the Money" during a respin.

Foster:
About using S+ reel chips in the S2000, if they are a 27C512 with an offset so they work in S+, will fail to work in the S2000.
The S2000 does not hold the additional address pins at a logic 1.

So if you have to make a S2000 compatible SS chip with a 27__512 (C or SF) no offset is used.

I would test a chip that was made for the S+ in the S+ (SST 27SF512) worked fine is S+ move to S2000. machine would show SS chip invalid.
When redid the chip without any offsets it worked.

Also the S2000 does not seem to damage the chips that you normally replace to do game change if you accidentally reverse them, but the S+ will every time.

Great post everybody and to Kevin for tying it all together. I vote sticky.

OhioGaming:
I am not 100% sure of this but think it is true.

A 27C64 at 120ns will work with older S2000 GMEs that are 4 meg.

A 27C64 at 100ns will work with newer S2000 GMEs that are 8 meg.

If someone else knows this is not correct .. correct me.

Will the "legacy sounds" be as "smooth" as in the S+ or will they have that "waveformy squareness" to them??
