That will superglue nicely on top of the NVRAM module. It's a bother reprogramming the NVRAM contents (you lose the MAC address, etc.) and I want a quasi-permanent solution, which the bigger AAA batteries represents. But it gets expensive putting a $5 pair of AAA lithium batteries in each machine when you have a lot of Sparcs. (the NVRAM FAQ says "it's best just to spend the $20 on a new NVRAM," but that's from an era when these Sun boxes were Big Bux and people didn't have a pile of them to maintain. $20 multipies out to a big number here, and just buying another 48c02 module sets me up for another $20 sooner than I'd want) Backup batteries in general is a topic worth pondering with 'vintage' computer hardware. -- http://sasteven.multics.org/MacSE30/MacSE30.html
