Not the straps of your boots, but “bootstrap”. It’s the way a computer gets itself going when you turn it on. Collectors can grow their collection more quickly with the Bootstrap Pack. This pack guarantees TWO upgrade cards, which otherwise would be a 29% (Common Upgrade) or 7% (Rare Upgrade) chance per slot purchased from the Standard Pack. This pack is competitively priced at exactly 1/10th of the IBM PC’s original purchase price on August 12, 1981. Only 64 Bootstrap Packs will ever be available.
