In regards to the possible battery in a NeXTstation. Also, this post is appropriate to the discussion on "inventory".
Check the large Panasonic lithium battery on the [NeXT] motherboard, like a Mac II, it will not boot with a dead battery. They are still produced and available from Mouser, the Mac cubes and the slabs use the same type of battery.
Caution: the lithium batteries used in various computers to keep time-of-day running, and to retain other information (as in "Mac PRAM battery"), have good odds of *leaking* and emitting hydrogen or other gasses. The results are very, very damaging, and often not repairable. Details: Any vintage Mac collector, and some owners, have had the horror of opening their Mac and seeing several square inches of circuit-board covered in goo. And, adjacent metal surfaces covered in red rust - not just discoloration, but deep rust. Components in the vicinity, have rusted leads and through-holes on the PC boards. These are not repairable. I'm sure there's pictures on the Web of such damage. I myself, checked out several Macs recently, and found one so rusted by leakage, neither case nor motherboard was salvageable. The Mac Plus/128K/512K, has a large 4.5v battery, in a holder accessed without disassembling the case. Leaving the battery in those units, almost guarantees the battery-holder will green-rust and corrode. No battery is needed to operate these oldest Macs. Bottom line Suggestion: While the VCF Museum is doing their inventory and cataloging, it may be a good idea to inspect computers for these batteries *and remove those batteries* if not wired in. I suppose a note can be added inside the computer, to specify the kind of battery removed and where it was connected if not obvious. If it's known the computer won't start without a working battery, add that info to the note. Comment to "this is too complicated, too much work, etc." This is the cost of long-term ownership. The space and time taken by a computer, will be lost if it it self-destructs and that's not discovered until that computer is needed or accessed. Herb Johnson retrotechnology.com -- Herbert R.
