Sheesh, I'm finally back at this one! I've got the boards spread out again and I hope this time I can find the problem(s).
A friend verified/burned all of the eproms, so I feel good about it not being one of those.
I've checked the reset pin, and it is pulsing about every 0.5 sec.
4.94v across the ram @ 5G. I swapped it out with Cmndr Brain's 6116 Nvram adapter, just in case the original ram was bad. No change.

dont forget reset. Reset comes from the power supply and is often damaged when the original battery out gasses.

so whats the voltage rating on across the RAM chip (5G) in question (pin 24 to ground). also I see in previous posts you've replaced the 6116 at 5G did you replace it with a low power 6116?
you need a low power 6116 in that spot when using the battery.
(and definitely you do need to make sure the reset is also working as gamefixer mentioned)
