Almost everything with a computer connects wirelessly today. The network, mouse, keyboard, printer, etc. That wasn’t always the case, though. Cables were used to connect everything, including this handy 30-inch parallel port printer cable. RadioShack also had a wealth of equipment to make your own cables. I hated short cables, so I was always making my own RJ 11 (phone) and RJ 45 (computer) cables, and I got all the parts – spools of able, ends, and crimping tools – at RadioShack.
