Here's some pictures of IGT Black Jack s plus, from 1990. It must be one of the first s plus mashines?
It's an intermediate model. Sp1168.

The S+ began prior to 1990, I think it was 1987? Someone will no more of an exact date.
-
The oldest S-Plus I have seen was made in mid 1989. I have often wondered when IGT officially rolled out the S-Plus line. I have some old model S games, some made as late as 10-1988. I wonder if 1989 was the year of release?

I found this note from 1989 inside tre mashine

My first machine was a Jackpot Jungle that looked exactly like that. The crew out here years ago told me that it was an S. If you put up a video of it playing, I could tell you if it was an S or S+ based on the spin sounds. S was a little more lethargic sounding compared to the S+ spin sounds. I'm betting yours is an S as well.
Thanks,

Here's what I mean about the spin sound comparison between an S and an S+:
Look at the button style and listen to the lethargic reel spin sounds of the S...also the "Insert Coin" style to the right of the denom legend is different:

Here is an S+...notice the different buttons and traditional sounding S+ reel spin sounds:

Maybe others can chime in with their experience, but this was what I was told back in the day...
Thanks,

The bottom one you posted, Jason, is a newer style S+ cabinet (notice the "Good Luck!") in the 4th reel window, which would typically have the "insert bills below" arrow if there was an embedded bill validator). There were indeed early S+ machines that used the older style buttons like in the top video and also like ersk3's machine.
From my understanding, the main difference between an "S" and an S+ is in the MPU board. The MPU board on an S used wire harnesses that had to be plugged and unplugged by hand to remove the board, while the S+ design used the fixed motherboard in the bottom of the machine with the connector that the S+ MPU board would just plug directly into. No need to plug in wire harnesses by hand -- just remove and insert the board, with the power off of course, and it would be disconnected or connected.
ersk3, can you post a picture of the inside of your machine where the MPU (processor) board is?

Here's some more pictures from the machine. The mpu board is plugged directly into the motherboard.

It looks just the same as my 1992 intermediate double diamond machine. The game sycle and sound is the same as in the first video posted on both machines.

That's an early S+, the mpu board is a give away, plus the fact that it uses an SP chip. The "S" had the reel and sp chip into one.
