This guide is compiled from several other rarity guides, interpolated with our own observations. In general, the list is bookended by the most available handheld calculators on the common end, and the early 2100 and 3000 minicomputers on the rare end.
Please take this list with a grain of salt. The rarity of any given model can change greatly from year to year, but this table should give collectors some idea of what is rare and what is not.
