Additionally there were eight storage registers and specialized scientific and statistical functions.
2.
Introduced by Hewlett-Packard in 1975, it featured twenty storage registers and room for 49 keystroke instructions.
3.
DSZ ( Decrement and Skip on Zero ) : Decrements storage register zero, and skips the next instruction if the result is zero.
4.
In 1965 Victor Comptometer Corporation produced the Victor 3900, a fully electronic calculator with multiple functions, three storage registers, and a small CRT display.
5.
Motorola's latest G4 chips, used in Apple's new line of computers, contain 32 storage registers for their MMX-like hardware, which is known as AltiVec.
6.
The " Series 50 " models were low cost versions that ran at a slower speed, with half as many program steps, and fewer storage registers and counters.
7.
The successor "'HP 10bII "'( F1902A ), which was introduced in 2001, is essentially a cosmetic upgrade offering the same overall functionality, but actually reduces the available numbered-storage registers from 15 to 10.
8.
Two later versions named TI-57 LCD and TI-57 LCD-II have a LCD display, but were less powerful ( ran much slower ) and had much less memory : 48 bytes to be allocated between program'steps'and storage registers.
9.
The HP-65 had a " feature " whereby storage register R9 was corrupted whenever the user ( or program ) executed trigonometric functions or performed comparison tests; this kind of issue was common in many early calculators, caused by a lack of memory due to cost, power, and / or size considerations.
