Quoted from PinballManiac40:BTTF is the easy plug and play. https://www.pinitech.com/products/6264_nvram.php
A word of advice on Data East- Leave the batteries in, swap the chip, boot the machine, shut down the machine and then pull the batteries.
On my Time Machine it would not work correct till I took the step of leaving the batteries in for the first boot. After that it was fine.
Quoted from barakandl:Data East games have memory protection on the coin door. Normally you just need to remove batteries, install the nvram module, open the coin door, and then power cycle twice. Then it should revert to factory default settings then you can setup the audits/adjustments to your liking.
Nope, mine was a bear. Tried several times.
Left the batteries in for first boot and bam, worked like a champ ever since.
Just figured I'd throw that out there in case someone else had the same odd issue.
Quoted from barakandl:Odd issue I have never heard of. Really should not matter batteries in or out because there is a low v drop diode powering the ram off of the +5v.
You would think but the machine would not even boot up correct with the NVRAM in place and no batteries. Had a flashing PIA LED light, displays were doing all sorts of strange stuff.
Guys were telling me "it takes 2 or 3 tries to catch" and it never did. Almost returned the NVRAM (which was from another vendor) and decided to try it with the batteries in. Glad I did!
