Discussion about foamed boxes to move S-100 chassis, caught my eye. ONe consideration for hobbyists is to acquire th epacking from local resources - say the big box hardware stores, found boxes. Hardware stores have best prices on heavyduty moving boxes of size, and packing materials. Taking time to make your own moving boxes gives you good storage boxes too. Make sure the boxes you use have heavy cardboard - not thin boxes to ship paper towels! Myself, I have used sheet styrofoam insulation, cut-to-fit whatever box, assembled around the S-100 chassis. The pink insulation is firmer and good for outside layers. The white insulating is yielding and good for the inside nearest the chassis. Not a bad idea, to have a layer of big-bubblewrap as a cushion on the bottom of the chassis, for a little bounce. Or some semisoft foamy carpetpadding (not the chunky composite stuff). Fabric stores sometimes have foam padding on sale. Or find some yoga floormat that's too soft at a thrift store. By big bubble bubblewrap, I mean like one-two square inches. Not air bags, if one of them breaks you got nuttin. Bag the chassis, to keep the dust and styro bits out; what used to be called "recycling trash bags" are transparent (you can't put recycles in plastic bags anymore), but get bags with some thickness if you can. YOu can cut-out areas in foam, where you have extensions from the chassis, like front-panel toggles. Fill in empty space not full of toggles, with large-bubble bubblewrap. Small bubble bubblewrap is OK for light flat objects, not heavy items. Where to get boxes other than hardware stores? Dunkin Donuts, small retailers, some groceries and dollar stores (some have policies against). Shop your local dumpsters. Knowing the sizes you need, gives you opportunities in-the-field to find such things when you see them. With luck you'll find styrofoam too, bubble wrap. PS: For Apple II owners: I found 25-pound mozzarella boxes really good for Apple IIs! Fit is good and the sides overlap, very sturdy. Don't tell Grandpa it's icky to pull stuff from dumpsters. Save the planet from throwing out things still useful and filling up your local landfill - your trash taxes pay those landfill fees. Dumpster reclamation is how you ended up with your IMSAIs and Altairs, you know. ho ho ho Herb Johnson still not a bot -- Herbert R.
