16 mhz or 10 mhz

[therockinelvis]

Just read on Ebay that the 16 mhz board is an upgrade for S+. Does the motherboard have to be changed also? It said that game and reel chips would not interchange from 10 to 16 and that the volume control is not on board but in programming. What other Pro's are with the 16 mhz board? I have not come across a 16 mhz in any the the machines I have bought.

I have a 16 MHz board in one of my S+ and the only difference I
see is the machine will coin up faster from credits and on a win,
the win will transfer to credits faster.

I'm no slot tech or guru by any means, but I do have a 16mhz board in one of my S+ machines. The 'hissing' , 'feedback' , 'static' noise that comes from the speakers regardless of volume setting is pretty annoying. I'm actually making that machine into a 'Haywire' just so it seems somewhat normal to other people.

I know that doesn't answer your question(s) but just thought I'd mention what I DISLIKE about my 16mhz board. - I've read that it's notorious for making those noises. -

the mother board does not have to be changed .. the credit speed is faster .. it does require certain diff chips in order to work .programing on sound is done on board set up . if you use it on a HAYWIRE GAME OR CHAOS OR GO BANNANA'S ETC ANY RE SPIN TYPE GAME ..THE SOUND THAT COMES OUT -IS NOT TYPICAL ..>>>>YOU WILL HATE IT << IT SOUNDS LIKE A CAT IN A BLENDER WHEN ON HAYWIRE MODE ..
other than speed of credits and a few other options its a great board but most folks end up putting back in the standard board .
just going by memory .. you cant use a # 731 game chip -you need a #1271 game chip . in order for it to work ..

THAT ANNOYING  "HUM" NOISE !! THAT THEY PRODUCE OUT OF THE SPEAKERS IS ANNOYING AS HELL .UNLESS YOU ADD A FEW THINGS INLINE WITH THE SPEAKER WIRES TO SUPPRESS THE NOISE .

plus in the past they cost more .. but the last time i purchased 5 on ebay ..i won them for .99 cents each .. SIGNS OF THE POOR ECONOMY ..

Joey is selling 10 on Ebay brand new never used $40.00 ea. inc. shipping.

The reel chip can be the same - you just need to ensure the eprom is faster. I think the 150s are too slow, I think the 120s are ok.

The game chip is different as it carries different programming to support the software controlled volume.

I concur that the high frequency sound is annoying.
I have heard you can use a 10k resistor from the speaker to ground to eliminate this but I have not tried.
In a casino the hum was never an issue.

This is often what is used in car audio systems to eliminate spark plug noise.

For the typical home user, the 16mhz board is really more of a downgrade than an upgrade.  If your machine operates with a 10mhz board (most S+ machines do -- the only exception would be the S+ Barcrest games and other specialty games), there is zero reason to change to a 16mhz board, and a few good reasons not to (static sound issues, inconvenient to adjust volume, limited number of SP chips that support 16mhz).

Well this has been educational for me. Now I know about the volume control and speaker noise when I come across a 16. And know there is no good reason to change any boards unless changing a game to a barcrest or haywire types. For all the info. I say "Thank-Ya-Thank-Ya-Very-Much"

you may of done a typo ..YOU DONT WANT TO USE THE 16MG BOARD ON THE HAYWIRE TYPE GAMES .. IT SOUNDS LIKE A CAT IN THE BLENDER .. NOT A BAD IDEA .. sorry Jay .

Agreed, only a very few S+ machines (like the Barcrest S+ machines that have a special top box bonus module) require the 16mhz board.  You can have Haywire games on a 10mhz board.
