I have had a check of all my 1.6 except my still inbox never opened clear, all the 1.6's look good just my earlier 1.0/1/2/4 that look like they may need to be removed some sooner than others.
IIRC I already have an error 16 fixed bios. one way to find out would be to pull one and see what happens. As far as the 1.6's are concerned I may just look for a cap that will do the job and swap out, we all know how much a PITA 1.6 can be modding anyhow, so I don't to increase my chances of getting a new Xbox door stop.
In the old days Amiga computers used rechargable nicad packs for the RTC, they are now 20+ years old and my A2000's one has started to leak in the same way as the Xbox, although not as destructive providing you dont power up before cleaning.
The modern replacement is to fit a CR2032 battery and a diode to stop the Amiga trying to charge the CR2032 bat, thus making it like a modern IBM clone PC. Once the bat runs out chuck it and replace, may be something similar would work on the Xbox.
I have a digital clock that works on a CR2025 which is similar to a CR2032 and I retrofitted it with two 1.5 AA bats to make the 3V, as it only lasted a year on the CR2025 three and a half years later and it is still going. Plenty enough room in the Xbox for that kinda thing.
