I have two questions:  I'm going to change the name in the mastercom  -
1.  Does anyone know what what type chip that's in it?  Whenever I try the ID function on my programmer it doesn't work.  :60-

2. Has anyone played with the SlotLine jack to communicate with this thing?   I did some searching but came up blank.

Thanks

AMD Am29F040B

Thank you!

jdkmunch, did you happen to see these posts?

Some of these are also using a 29F010 too.

I did - I just found out what chip it is AMD Am29F040B or 29F010.

So I'll change the name on the display tonight.  I would like to communicate with the box - maybe set up a database and have valid cards.  Track points etc.  

Hmm, here comes the brain picking!  :88- :97-

Seems kind of odd that they would use either a 1Mbit or 4Mbit in the same application, but the manual does state that it supports "up to" 512k memory. Is there less functionality with the units that use the 1Mbit eprom? Is there a reason to want to upgrade the eprom if it's 1Mbit for home use? Yes, I'm nerding out again! :5-

Stat, we need a nerd smiley, please do the needful:

Which eprom do you have?

I don't know yet - I have to scrape off the bally sticker to reveal the window and numbers.

If it has a window it wont work, well unless someone jumped pins.  It should be a flash chip that erases in your programmer.  These work wit 1meg, 2meg or 4 meg chips, the 4 meg file can be used on a 1 meg chip and it will work.

ohhhhh I didn't know that - Thanks It saves me scraping the label off it.

Just burned chip and it worked great! It's the Am29F010 chip.  I sure would love to talk to this thing though. 

I lied... I used AM29F010 because it was printed on the circuit board but in fact the chip is AM29F040.   I ruined the bin and now it's useless  :37-


The thing just says booting... because I didn't get the complete image of the chip.  :30-

try again with your programmer set for the correct chip.  What casino was it from?

I tried.. I erased the chip and burned the image that I made back on with no luck.   The casino was Pearl River Resort.  When go down past address 001f550 the chip is blank.


*** - The original image that was on the chip ***   - I think because I had the wrong chip size I only copied 25% of the chip.

I may be able to help you out, I have some pearl river chips, I'll look for them.  I doubt that's why it wont work though. I bet you went outside of the editable area.

Thanks,
Wayne

But even the unmodified version doesn't work.

Would it matter from one casino to another?

I'm sure you have the notch to the edge of the board.  Isn't your chip an amd am29f040B??

Thanks,
Wayne

The Pearl river is an easy one to mod.  I have seen some that are encrypted.

Thanks,
Wayne

didn't you have more than 1, just try the chip from your other mastercom.

Thanks,
Wayne

That did it! -


So the moral of the story is don't backup 25% of your chip.  It won't work!
 

The name change worked fine to.  Amazing what those extra bits will do!

Has anyone read the article "Unlocking the Mysteries of the Mastercom 250" from Slot Tech Magazine?   

Got a link???

I don't because only subscribers can get to it.  The issue that has info on the 250 is June 2006

Well, THAT'S no fun! :30- :30-

You will find it in the smiley popup window amongst the other smileys, so nerd away whenever you please! :186-

Thanks! I nerd away every chance I get... :186-

I'm playing with a couple of Bally Mastercom 250's right now.
I wanted to get into the Test mode...would anyone have a old GMU or "SKEY" card?
With this card I would be able to run tests for the "events" such as "Door Open", "Drop", "Cash Box"
so on and so on...
This seems to have a really neat 2x20 LCD display and I want to see if
I can get it to display other messages such as "Winner!", "Jackpot!", etc etc...by using relay triggers and stuff...

Got some mail for you

Hi SB

You can find the manual on Randy Fromm's excellent FTP site - http://slot-tech.com/interesting_stuff/bally/mastercom%20250/
