The keyboard, mouse, display, disk drives and network were all controlled by a microkernel.

Among the kits sold there were also alternative floppy disk drives for TRS-80 computers.

In the early 1990s a small number of BBSes were also running on the Commodore Amiga models 500, 1000 and 1200 ( using external hard drives ), and the Amiga 2000, Amiga 3000 and Amiga 4000 ( which had built-in hard drives ).

B205 tape drives were often seen in series such as The Time Tunnel and Voyage to the Bottom of the Sea.

Failure rates on the 1541 initially were very high, and the drives were virtually impossible to find.

Well-known clones were the Oceanic OC-118 aka Excelerator +, the MSD Super Disk single and dual drives, the Enhancer 2000, the Indus GT, and CMD's FD-2000 and FD-4000.

Disk drives and other peripherals such as printers were connected to the computer via a daisy chain scheme, necessitating only a single connector on the computer itself.

Even though each 1541 had its own on board disk controller and disk operating system, it was not possible for a user to command two 1541 drives to copy a disk ( one drive reading and the other writing ) as with older dual drives like the 4040 and 8050 that were often found with the PET computer, and which the 1541 was backward compatible to ( it could read 4040 disks but not write to them since its internal Operating System was essentially the same ).

This controller chip, however, was the seat of some early problems with 1581 drives when the first production runs were recalled due to a high failure rate ; the problem was quickly corrected.

For example, the IBM 350 disk drives were called " disk files ".

For compatibility and ease of implementation, the 1571's double-sided format of one logical disk side with 70 tracks was created by putting together the lower 35 physical tracks on each of the physical sides of the disk rather than using two times 40 tracks, even though there were no more quality problems with the mechanisms of the 1571 drives.

Although superior to paper tape, DECtapes were relatively slow, and were supplanted as reliable disk drives became affordable.

In the early days of computers, there were no disk drives, floppies or modern flash storage devices.

Most home computer DOS ' es were stored on a floppy disk always to be booted at start-up, with the notable exception of Commodore, whose DOS resided on ROM chips in the disk drives themselves ( the computer itself had no DOS, just a form of a BIOS for communicating with peripherals ).

Hard disk drives were introduced in 1956 as data storage for an IBM real-time transaction processing computer and were developed for use with general purpose mainframe and minicomputers.

As the 1980s began, hard disk drives were a rare and very expensive additional feature on personal computers ( PCs ); however by the late ' 80s, their cost had been reduced to the point where they were standard on all but the cheapest PC.

Most hard disk drives in the early 1980s were sold to PC end users as an external, add-on subsystem.

While the SSDD drives initially were the only floppy drives available for the model 5150 PC, IBM later switched to DSDD drives, and the majority of 5150 PCs sold eventually shipped with one or two DSDD drives.

Encryption can be used to protect data " at rest ", such as files on computers and storage devices ( e. g. USB flash drives ).

:# Jet-Disc Disc Drive System ( 1983 ) by MPE ( control up to four 3 ", 5 ", or 8 " drives ).

Most CD-ROM drives dependably return an error for the unsupported CD-RW command, but the faulty drives interpreted it as " Update Firmware ", causing them to be bricked.

Most interplanetary communication is handled by courier ships, most commonly " X-boats ", which are small Imperial vessels with long-distance jump drives that travel between systems transmitting and receiving vital data.

For example, in the " Indictment of Madduwatta ", Attarissiya, the " man of Ahhiya " ( i. e. ruler ), attacks Madduwatta and drives him from his land.

Kenneth Turan of the Los Angeles Times said the actors coped " faultlessly " with what were difficult roles ; he called Spacey's performance " the energy that drives the film ", saying the actor commanded audience involvement despite Lester's not always being sympathetic.

" It is commonly stated as: " Bad money drives out good ", but is more accurately stated: " Bad money drives out good if their exchange rate is set by law.

In this volume he attacks the " repressive hypothesis ", the widespread belief that we have " repressed " our natural sexual drives, particularly since the 19th century.

It can refer to the technical aspect of storage and transmission ( e. g. hard disk drives or computer networking ) of information or to the " end product ", such as digital video, augmented reality, digital signage, or digital art.

IBM's line of Deskstar hard drives ( and to a lesser extent Hitachi's ) are colloquially referred to as " Deathstars ", especially the very unreliable 60GXP and 75GXP models.

Data is distributed across the drives in one of several ways called " RAID levels ", depending on what level of redundancy and performance ( via parallel communication ) is required.

The physical drives are said to be " in a RAID ", however the more common, incorrect parlance is to say that they are " in a RAID array ".

* A: — Floppy disk drives, 3. 5 " or 5. 25 ", and possibly other types of disk drives, if present.

The mind of a newborn child is regarded as completely " id-ridden ", in the sense that it is a mass of instinctive drives and impulses, and needs immediate satisfaction, a view which equates a newborn child with an id-ridden individual — often humorously — with this analogy: an alimentary tract with no sense of responsibility at either end, paraphrasing a quip made by former U. S. President Ronald Reagan during his 1965 campaign for Governor of California in which he compared government to a baby.

Fantasia is also referenced in the animated series South Park in the episode " Chef's Chocolate Salty Balls ", where Mr. Hankey dons a wizard outfit and drives out an independent film festival by summoning a wave of sewage, similar to Mickey's dream of summoning a storm in The Sorcerer's Apprentice.

* Antigonus drives out Cassander's Macedonian forces of occupation from the Greek islands and forms the island cities in the Aegean into the " League of the Islanders ", preparatory to his invasion of Greece.

He possesses a mix of courageous altruism and a gigantic arrogance and ego, two drives that constantly clash during his adventures-in " Just Us Justice Ducks ", he was initially mortified that he'd be getting help against the Fearsome Five.

Thus while defenders argue that the three-prong test embodies the maxim that " opportunity drives interest ", critics argue that the three-prong test goes beyond Title IX original purpose of preventing discrimination, and instead amounts to an exercise in which athletic opportunities are taken away from male students and given to female students, despite the comparatively lower interest levels of those female students.

* Patrick McGoohan drives an SM in a 1975 episode of the American television series Columbo (" Identity Crisis ", Season 5, Episode 3 ), while Gerry Anderson's 1971 television series The Protectors featured a platinum blue SM.

* Big Ole Badass Bob The Cattle Rustler – an American Westerner / Texan who drives a semi-truck ; has appeared on " Lawnmower Sale " and " Bad Ass Massage ", both from The Jerky Boys 3 album, " Flower Lady # 4 " from The Jerky Tapes album, and is a featured character on Sol's Rusty Trombone ( voiced by Johnny Brennan ).

Overpopulation also drives export of manpower to India, the Middle East, Europe, Australia and North America in search of employment, the so-called Nepalese Diaspora.

* " 5. 25 inch " drive: ( 5. 75 in × 8 in × 1. 63 in = 146. 1 mm × 203 mm × 41. 4 mm ) Most desktop models of drives for optical 120-mm disks ( DVD-ROM or CD-ROM drives, CD or DVD burners ), are designed to be mounted into a so-called " 5. 25-inch slot ", which obtained its nickname because this slot size was initially used by drives for floppy disks in the IBM PC AT.

A similar sensibility drives the so-called power cruiser motorcycles, based on cruiser class machines but with horsepower numbers in league with superbikes.
