Storage Hazards

Your copies get a little sticky at warmer days, and the pressure inside the binder is doing the rest. I guess that you are right when you say that *any* batteries cause corrosion over time. I never saw batteries made of *one* piece of metal enclosure. There must be some opening in that case to get the two poles (as wires) to the outside world. Et voil?: there you have the weak spot that eventually will cause a leak! BTW an other place toi check for leaky batteries are DECstations and VAXstations (or ...servers). They also have a NiCad (!!!!) "on board". - Henk, PA8PDP ; Be careful with laser-printed documentation in ring binders too; the ; text has a habit of sticking to the underside of the binder's cover for ; some reason - stick a blank sheet of paper in there to protect it. ; ; > * Leaky nicad batteries that will "eat" the circuit board traces ; > The early computers that come quickly to mind are the TRS-100, Lobo ; > Drives Max 80, NEC 8201A, 286 and later motherboards, and S-100 ; > CompuWatch Clock/Calendar boards.
