Extra features/remarks:  

From a technical brochure: (Thanks to Professor Elliot Tanis for this info)
The lME86 is an all new second generation, solid-state electronic calculator.
It has the exclusive ability to offer up to seven random access working/accumulating registers allowing the user for the first time to solve mathematical problems, both commercial and scientific, just as they are normally written on paper without re-sequencing or rearranging them to "fit" the machine.
Answers are virtually instantaneous.
Additionally. the new machine offers fully automatic re-entry from all registers and comes equipped with an exclusive input-output capability permitting direct connection to satellite keyboards, programmers and other input-output accessories.
Additional unique features include:
REGISTERS: Three operational and four accumulating registers,
CAPACITY: 16 digits and sign in all registers,
DECIMAL SYSTEM: Fixed decimal point position in both opera tional and accumulating registers, with unique facility that this position can be changed at will at any time, CLEARANCE: Automatic clear ing of the operational registers. The accumulating registers are cleared by individual keys,
CHECKS: Overflow signal in all operations. lndication of negative sign in all registers. Visual check of all factors in a calculation without reference to a printed tape.
Other characteristics include:
Visual check of numbers being entered and of decimal point position.
Addition, subtraction. multiplication or division in the operational registers or directly into the accumulating registers, without a transfer operation.
Multiplication with automatic round-off.
Division with visual check of the remainder,
Raising to power of whole or decimal numbers with continuous visual check of the power
index,
Instantaneous square root of whole and decimal numbers with visual check of the remainder,
Automatic accumulation of multiplicands,
Operation item count and arithmetical average,
Chain operations with or without reading of immediate results.

Multiple versions do exist, (see: below).
