Your memory is faulty. No Hewlett-Packard 20-series calculator ever cost
half that much. The hp 65 cost $800 in 1974 (maybe 75). The hp 67 and 97
also cost over $500 a few years later. The subsequent top-of-the-line hp
calculators cost significantly less than $500. The current top-of-the-line
hp calculator is the hp48G, which is often discounted to less than $100, and
worth every penny.
