Need Old Player Cards for Bally Mastercom - Need Track 1 Format

[Eddiie]

Hi,

I am working with the Mastercom Card reader.  Every card I put in, the device just spits out an ack.    I assume this is because the onboard controller is looking at the data and rejects it because it is not in a certain format.   What is this format?   It is on Track 1.

Anyone out there have an old player card that would have been used on a Mastercom system?
How about an old school / outdated employee card?

I really hate answering my own posts.

Did a search on ebay and found tons of old player card lots up for bids.   
Meanwhile, I tried a different card reader and evidently was using an old dirty one, and found what I was looking for.
The card reader is looking for a string of 6 hex values.  There is a 7th one, low ordered bits, 0-f only.
It was an amazing feeling after hundreds of 0x30,  to suddenly getting a bunch of data back.

This sounds like a cool project - have you been able to find a card writer ... so you can create your own.

Yeah any Track 1 programmer will work.


So here's something interesting, I think......

I got one of the Mastercoms from the Trump Taj Mahl, ROM file attached.
I acquired a couple of Trump Taj cards from ebay.
I plug it in, insert the card...

It says ACCEPTED!!!    The LEDs around the card reader turn green.

Cool.

I experiment some more,  push button 1.     The display changes to  "Change Request"  or something, the LEDs around the card reader start to chase Green.
Cool.

I hit 1 again, it cancels the Change Request..      Hit button 2,  Service Request, same thing happens, LEDs turn green and run in a circle around the card reader.
Cool.

2 cancels.    3,  same thing, another Request, I forgot the exact one. 
Cool.

3 cancels.

Button 4,  screen clears and says  Enter Service Code  >   (or something similar to that).   I enter some numbers..  Doesn't matter how many..

Screen says  "Sending..........."
pause
Screen says "Accepted"   or Sent..     

Cool.

I'll make a video and post it.


Does anyone out there maybe know anyone that might have been a slot tech at the old Taj in Atlantic City that might still have their  Employee card? heh heh
There has got to be a configuration menu of some sort or diagnostic menu somewhere, I see it in the bin file.

Hello
  What happens when your leave it in ?  Does it stay green or does it go red  after a while ?
Thanks

Yeah, eventually it flashes Red and the displays says REINSERT, not sure how long maybe 5 - 10 minutes.
