Sharp's primary product in consumer calculators is its ELSIMate line of digital calculators. The first item in the line, the EL-8 was released in 1970, and the latest version of the ELSIMate can be purchased at Target or Circuit City today. The 819 is one of only a few calculators in the line with a nifty "chime" function -- turn it on and the calculator delivers a melodic note with every press of a button. This item is in excellent condition, tested and working. It has been velcroed into a faux leather Ampad note-pad holder which provides excellent protection and portability.

An early instance of dual solar power in the ELSI line; this would become the standard for pocket calculators. This item is in excellent condition and comes with its original box, which is in very rough shape. 

If you are from the Saved by the Bell generation, this is probably the calculator you bought when you first took trigonometry. This item is in good working condition but does not have its slide-on cover.

This item is actually pretty hard to find -- the 323 was only manufactured briefly before the release of the updated 325. This Sharp pocket calculator is in good working order and includes, intact and in good condition, it plastic pocket sleeve. This sleeve holds the calculator in place with plastic strap holders that were replaced on some later models with strips of adhesive. 

The SL line is pretty close in form and function to the ELSIMate calculators from Sharp. This item is in good working condition and comes with its intact original sleeve, and also, for kicks, includes the original warrantee slip in the sleeve's card holder. I don't imagine the warrantee is good any more, but that's okay, because these things never break.

This is the modern update to the SL-300, with a nearly identical design to the classic original. Also in good working order.

This is the stand-out item in the collection. A basic and very early pocket-size electronic calculator with a blue fluorescent readout (the rest of the items in this list have LCD displays, and most of the earlier calculators have red LED displays; this Lloyd's item is a rarity.) The Accumatic 30 was manufactured for only one year so it's pretty hard to find. It features a physical on/off switch and a port for AC power. Important Condition Note: Due to age, the plastic battery cover on this calculator had shattered into several pieces. It has been repaired but not in a "beautiful" way -- the pieces were first reconstructed with cyanoacrylate adhesive (Super Glue). Several holes were then drilled into each piece and a layer of common 2-part epoxy was applied. The result is a stable and functional battery cover that is not at all attractive; it definitely detracts from the aesthetic presentation of the machine when it's turned over. 

Another modern update to the classic Casio pocket calculator line, in this case a new version of the SL-310 that was originally released in 1984. Other than aesthetics, nothing has changed -- not even the dimensions.

RealTone is a less-well-known brand that had entries in all of the major pocket calculator lanes early on, including a very functional scientific calculator, the SC-60. This item is a circa-1980s standard 4 function desk-top style calculator with dual solar power. Works great.
