+acadiel Posted September 16, 2021 Share Posted September 16, 2021 Some interesting things I’ve found with my Grand RAM…. 1) U13, 74LS05 has a purposely bent out pin (10?) 2) Jumper wire between the 9901 pin 2 to U22, pin 10 3) Jumper wire between U9, 74Ls242N pin 12 and Q3 4) Jumper between what’s supposed to be D4 and R11, along with a cut trace between Q3 and R11. 5) A resistor across U17, pins 26 and 28. 4 Quote Link to comment Share on other sites More sharing options...

+dhe Posted November 29, 2022 Share Posted November 29, 2022 my battery is a bit different, and not sure how to desolder: I'm thinking I start with the 3 big globs of solder? Quote Link to comment Share on other sites More sharing options...

DSADA00289.pdf 8.3 MB · 9 downloads I haven't replaced mine yet, and thankfully there wasn't much battery leakage at all, but I eventually do want to replace it. However, I don't want a potential leak candidate again, so I've been looking at supercaps. I just need to figure out how much amperage draw these things have and get some help doing the math to see how long it lasts when the PEB is off. 1 Quote Link to comment Share on other sites More sharing options...
