DEC quad board rack

Noel, I recently I picked up a dozen or so spare boards for my PDP8E. I was wondering about how to store them. Some guys recommend some poly bags, others say it is important to protect against humidity. You sure have a boat load of cards, have you had any failures while in storage?

It's much better than the dual rack next to it, which holds them horizontally, which has the issue that the distance between the sides needs to be absolutely perfect, otherwise the boards tend to drop out of their slots. With the boards held vertically, it's much less sensitive. If anyone's interested in building one, I can whip up a drawing. (Note that the slots are offset slightly to the left because one needs different clearances for the solder and component sides.) The one shown uses 3 pieces of 1"x8"x6' (not sure what that translates to in that new-fangled French stuff :-). It would be tricky to make without a radial-arm saw, though - although I suppose a router with a small bit could be used, albeit tedious. ??? Noel
