Just sell or trade it to me and I will get it going. It will help me relive my days at our local roller rink!

The chips shouldnt be game specific. Try arcadechips.com

Try re-seating the connectors between the vidiot board and the mpu.

What are the numbers for the chips U9 and U4?

Yes, actual numbers off the chips. If the numbers are the same, they will probably interchange. If the numbers are not the same, you can find the pin-out to see if they will interchange.

if the numbers arent the same then go to arcadechips.com and get some and replace them! Hes a great guy to buy from and is reasonable with his pricing.

See if this helps:

Do a CTRL+F for the "Baby Pacman Vidiot Board LED Flashes" section.

Since it doesn't make it to the third flash, there may be something that doesn't pass the third test.

3rd Flash.
After a pause, the 6809 CPU chip at U8 attempts to test the program EPROM at U12. This is done using a chksum routine. If the chksum is correct, the third LED flash is shown. If there is no third LED flash, the EPROM at U12 is bad (or its socket or a trace is broken going to U12).

A common problem with this design is the battery from the MPU board leaking and taking out the ROMs on the Vidiot board. You likely have battery damage and need to clean/change ROM/socket/board.

Because of the additional TMS9928 chip and added RAM/ROM on the Vidiot Deluxe, the LED boot up sequence is different. Note the LED flashes come very quickly are are not easy to count. Here's the codes. (A flash means that "check" is completely.)

I *think* the only difference between baby pac and gators is the vidiot board is a deluxe version in gators.

I've working on a vidiot deluxe board for Granny and the Gators for at least 2 months now and have three VD boards plus a second Working granny to test in. Here is what I've found with having experienced what you are going through. First off most Granny game ROMs are corrupted and need to be Re Dumped so do that first from U4 to U9, you can get a complete set from K's arcade for 65.00. The next thing I recommend is replacing and socketing U11 and U12 as these are the communication chips for that initial seek procedure for U9 once you do all that cross your fingers and you may get boot up if not where I am now is bad processor chips U3,U28 and U18 on all 3 of my vidiot deluxe boards these chips have corroded or broken legs, I'm up to 15 flashes and almost booting. Make sure you also check the legs of all the sockets for game ROMs as well as any other sockets I have plenty of cold solder joints on my sockets and corrosion under the sockets on one of my boards. Good luck it's frustrating but it will be rewarding bringing another Granny and the Gators back to life.

No idea man but don't give up!
