C26H54
(gcide) | Hexeikosane \Hex*ei"ko*sane\, n. [Hex- + eikosane.] (chem.)
A hydrocarbon, C26H54, resembling paraffine; -- so called
because each molecule has twenty-six atoms of carbon.
[Written also hexacosane.]

COC2H54
(gcide) | Orthocarbonic \Or`tho*car*bon"ic\, a. [Ortho- + carbonic.]
(Chem.)
Designating a complex ether, C.(OC2H5)4, which is obtained
as a liquid of a pleasant ethereal odor by means of
chlorpicrin, and is believed to be a derivative of the
hypothetical normal carbonic acid, C.(OH)4.

1541
(foldoc) | Commodore 1541
1541
The best known floppy disk drive for the
Commodore 64. The 1541 was a single-sided 160 Kb drive but
converting to flippy disks would give another 160 Kb.
The disk drive used Group Code Recording and contained a
6502 processor as a disk controller. Some people wrote
code for it to vibrate the head at different frequencies to
play tunes.
The transfer rate was about 300 bytes per second. The 1541
used a bit-serial version of the IEEE 488 parallel
protocol. Some third-party speed-ups could transfer about 4
kilobytes per second over the interface, and some "fast
loaders" managed up to 10 kbps.
The Commodore 1570 was an upgraded 1541 for use with the
Commodore 128.

754
(foldoc) | IEEE Floating Point Standard
754
IEC 559
IEEE 754
(IEEE 754) "IEEE Standard for Binary
Floating-Point Arithmetic (ANSI/IEEE Std 754-1985)" or IEC
559: "Binary floating-point arithmetic for microprocessor
systems". A standard, used by many CPUs and FPUs, which
defines formats for representing floating-point numbers;
representations of special values (e.g. infinity, very small
values, NaN); five exceptions, when they occur, and what
happens when they do occur; four rounding modes; and a set
of floating-point operations that will work identically on any
conforming system.
IEEE 754 specifies formats for representing floating-point
values: single-precision (32-bit) is required,
double-precision (64-bit) is optional. The standard also
mentions that some implementations may include single-extended
precision (80-bit) and double-extended precision (128-bit)
formats.

p1754
(foldoc) | P1754
IEEE Std 1754-1994 "A 32-Bit
Microprocessor Architecture". The IEEE standard defining a
version of the SPARC microprocessor architecture.
The P1754 standard (the first microprocessor standard) was
approved after four years on 1994-03-17. It is compatible
with, but distinct from, SPARC International's 32 bit
version of the SPARC Architecture, SPARC V8, from which it is
largely derived. It is possible for a processor to comply
with neither, one, or both specifications.
