Although GCOS has a basic architecture similar to that of the IBM 360 and subsequent operating systems with which it competed, it was also heavily influenced by projects such as MEDINET, Multics, and WWMCCS, and has inherited a strong security structure in consequence.

Although revenue from the initial OS / 2 release was never paid by the bankrupt publisher, popular support encouraged Stardock to release Shipyards, an add-on pack that allowed users to design their own starships, and this provided enough revenue to support further development, with a simplified version being sold to IBM in 1995 as Star Emperor.

Although not consistently in any manner, IBM preferred term at that moment was monitor.

Although they once did, IBM no longer manufactures printers.

Although the IBM PC Enhanced Graphics Adapter ( EGA ) standard offers a fixed 64 color space, it only allows 16 simultaneous colors ( 16 out of 64 ), and then only in the relatively slow and barely accelerated high-res ( 640x350 ) mode.

Although never documented by IBM, an alternative planar 256 color mode is available by " unchaining " the video ram ; video modes created using this technique are collectively called Mode X.

Although there is no legal entity that owns the OpenAFS source code, copyright on many files is attributed to IBM.

Although the design of the original Courier typeface was commissioned by IBM, the company deliberately chose not to secure legal exclusivity to the typeface and it soon became a standard font used throughout the typewriter industry.

Although ports for the Amiga, Atari ST, Macintosh and PC-9801 platforms exist, the primary development was for the IBM PC platform.

Although " android " is used almost universally to refer to both sexes, and those of no particular sex, " android " technically refers to the male form, while " gynoid " is the feminine form.

Although digital setting circles can be used to display a telescope's RA and Dec coordinates, they are not simply a digital read-out of what can be seen on the telescope's analog setting circles.

Although the name actually applies to a group of snakes, it is often used to refer only to one species in particular, the common or green anaconda, Eunectes murinus, which is one of the largest snakes in the world.

Although originally controversial, the axiom of choice is now used without reservation by most mathematicians, and it is included in ZFC, the standard form of axiomatic set theory.

Although the axiom of countable choice in particular is commonly used in constructive mathematics, its use has also been questioned.

Although an explanation for the phenomenon was not provided until 1919, duralumin was one of the first " age hardening " alloys to be used, and was soon followed by many others.

Although hydrogen-like orbitals are still used as pedagogical tools, the advent of computers has made STOs preferable for atoms and diatomic molecules since combinations of STOs can replace the nodes in hydrogen-like atomic orbital.

Although Collins used it as a catharsis for her opposition to the Vietnam War, two years after her rendition, the Royal Scots Dragoon Guards, senior Scottish regiment of the British Army, recorded an instrumental version featuring a bagpipe soloist accompanied by a pipe and drum band.

Although Dio is the earliest writer to mention them, Ammianus Marcellinus used the name to refer to Germans on the Limes Germanicus in the time of Trajan's governorship of the province shortly after it was formed, circa 98 / 99.

Although the 1987 decision settled the question of the scientific name of the genus, the common name " amaryllis " continues to be used differently.

Although the term aeon may be used in reference to a period of a billion years ( especially in geology, cosmology or astronomy ), its more common usage is for any long, indefinite, period.

Although most dialects of English used in the former British Empire outside of North America and Australasia are, to various extents, based on British English, most of the countries concerned have developed their own unique dialects, particularly with respect to pronunciation, idioms and vocabulary.

Although used for similar purposes, transparent colors and image masks do not permit the smooth blending of the superimposed image pixels with those of the background ( only whole image pixels or whole background pixels allowed ).

Although cheap and effective in enabling use of some software that only used official ROM entry points for text output, this solution proved very slow because the Electron had to be placed into an 80-byte-pitch display to be able to get anywhere near to reproducing mode 7 and the CPU spent a lot of time drawing approximations of mode 7 characters and graphics that in a hardware solution would be achieved without any CPU processing.

Although this produced a mode 7 that barely impacted upon CPU performance and gave the same visual quality as the BBC Micro, it remained compatible only with software that used the ROM routines for outputting text and graphics and still used 10 kB of memory for the display.

Although used during the Normandy landings, by that point German aircraft were contained by the Allies own air forces and they were largely unneeded.

Although modern analytical chemistry is dominated by sophisticated instrumentation, the roots of analytical chemistry and some of the principles used in modern instruments are from traditional techniques many of which are still used today.

Although he used the usual French terms " avant J .- C ." ( before Jesus Christ ) and " après J .- C ." ( after Jesus Christ ) to label years elsewhere in his book, the Byzantine historian Venance Grumel used negative years ( identified by a minus sign, −) to label BC years and unsigned positive years to label AD years in a table, possibly to save space, without a year 0 between them.

Although a wide variety of graphite tube designs have been used over the years, the dimensions nowadays are typically 20 – 25 mm in length and 5 – 6 mm inner diameter.

Although these instruments have slow response time and low accuracy, they were sometimes used in measuring radio-frequency current.

Although his paper was widely cited, a random selection of 60 of these citations revealed that 29 of the papers were direct rebuttals or criticisms of Jensen's arguments, 8 cited the paper as an " example of controversy ," 8 used it as a background reference.

Although this document was subsequently adopted by International Organization for Standardization ( ISO ) and subsequent revisions published by ISO have been adopted by ANSI, the name ANSI C ( rather than ISO C ) is still more widely used.
