Title: U24 ON BALLY 6000 Post by: FORDSBS on March 16, 2012, 05:42:46 PM I have a MPU board for a Bally 6000. On the MPU board the chip in U24 is missing.
Next to dip switch #1. Does anyone know what that chip is for? Thanks Ford Title: Re: U24 ON BALLY 6000 Post by: dhellis on March 16, 2012, 06:40:13 PM I am curious, is this a 16 pin chip? if so then it may be a 75ALS195

Does anyone know what that chip is for? Thanks Ford I dont know what the chip does but I do know you dont need it for progressive machines....Basically non progressives have them and progressive machines don’t. Title: Re: U24 ON BALLY 6000 Post by: dhellis on March 16, 2012, 07:05:02 PM yep, 16 pin. I was wondering what it was for. I think that this chip is only used if the machine is set up for progressive slots and it is not needed for normal operation.Title: Re: U24 ON BALLY 6000 Post by: b5srt on March 16, 2012, 07:27:24 PM [/quote] I think that this chip is only used if the machine is set up for progressive slots and it is not needed for normal operation. [/quote] It is actually the oposite....Progressive machines dont have them. It must have something to do with the Jackpot Title: Re: U24 ON BALLY 6000 Post by: dhellis on March 16, 2012, 07:30:56 PM [/quote] It is actually the oposite....Progressive machines dont have them.

So for non progressive I'll need chip.
Thanks Ford Title: Re: U24 ON BALLY 6000 Post by: dhellis on March 16, 2012, 07:46:25 PM It came out of a machine that had progressive. So for non progressive I'll need chip. Thanks Ford apparently so, you can order the chip from Mouser Electronics http://www.mouser.com/ProductDetail/Texas-Instruments/SN75ALS195N/?qs=sGAEpiMZZMutXGli8Ay4kHSEdT7wJpx2hxDV92B%252byzY%3d (http://www.mouser.com/ProductDetail/Texas-Instruments/SN75ALS195N/?qs=sGAEpiMZZMutXGli8Ay4kHSEdT7wJpx2hxDV92B%252byzY%3d) The chips is $2.04 but with shipping, you might be looking at $9 to $12, depending the method of shipping you choose. Title: Re: U24 ON BALLY 6000 Post by: gwizit on March 19, 2012, 06:04:14 PM I also have a Bally 6000. and on the MPU board the chip in U24 is missing.
It's not a progressive machine, but I just got it so not sure if it may have been. So from what I have read so far it needs the U24 chip if it's not going to be progressive? If So - Just getting a chip from above link and plugging it in will be OK? OR does the chip need to be programmed? Could this U24 chip being missing cause ERROR 88, since the MPU not picking up the progressive info? Thanks in Advance Title: Re: U24 ON BALLY 6000 Post by: dhellis on March 19, 2012, 06:32:39 PM U24 (75ALS195) is a logic chip and not programmable. It is a buffer which is why I initially
thought would be used only for progressive until someone corrected me. Hey I am no expert so I willingly accept the notes of those wiser than I. Unfortunately for you an Error code 88 is a catastrophic error :8- of unknown origin on the MPU Board The manual suggests that you send the board in for repair.

We're all placed on this earth to learn new things - Not to claim we know everything. Thanks for the information about the U24 - Guess I'll need to get one of those also. Take Care |
