The Acorn Plus 3 was a hardware module that connected independently of the Plus 1 and provided a double-density 3½ ” disc drive connected through a WD1770 drive controller and an ADFS ROM.

Per a News article on Page # 9 of the October 1984 issue of Acorn User, the Plus 3 was originally destined to have used the Intel 8272 disk controller, ( and not 8271, which were in short supply at the time ).

As Steve Wozniak, the creator of Integer BASIC and the only person who understood it well enough to add floating point features, was busy with the Disk II drive and controller and with Apple DOS, Apple turned to Microsoft, who was the BASIC vendor of choice after their success with Altair BASIC, and licensed a 10 KB assembly language version of BASIC dubbed " Applesoft.

But these needed the infamous TRS-80 expansion interface, which was very expensive, and had a very unreliable floppy disk controller because it used the WD1771 floppy disc controller chip without an external " data separator ".

Because the original designer had left the company another employee completely redesigned most of the system, ( adding a display snow remover circuit, true 80 / 64 column text mode support, ( with different size letters for TRS-80 and CP / M mode, so that in TRS-80 mode the full screen was also used, not just a 64x16 portion of the 80x25 screen ) with an improved font set ( adding " gray scale " version of the TRS-80 mozaik graphics and many special PETSCII like characters ), and a more flexible and reliable floppy disk controller and keyboard interface plus many other small improvements ), also an enclosure was developed for the main computer system, ( in the form of a 19-inch rack for the Eurocards ) and for two floppy disk drives and the power supply.

The 360-degree non-centering joystick was touted as offering more control than the eight-way joystick controller offered with the Atari 2600.

Atari Inc. released the Pro-Line Trak-Ball controller for the system, which was used primarily for gaming titles such as Centipede or Missile Command.

The primary controller was ranked the 10th worst video game controller by IGN editor Craig Harris.

Additional improvements were made in Windows Server 2003 R2, Windows Server 2008 and Windows Server 2008 R2, and with the release of the latter the domain controller role was renamed Active Directory Domain Services.

A video game controller called the X-SKIN, using this system, was expected to be commercially available by 2010 to help make MMORPGs popular on console systems and ease entry of common data such as a username and password, but announcement of its release was available on the In10did website as of 4 March 2012.

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.

They also released it as an Atari-compatible controller called " Video Command " it was also first released without the extra fire button, before that only the downwards plunge motion was connected and acted as the fire button, the pull-up and twist actions weren't connected to anything.

Reading Atari 8-bit 130kB or 180kB disks was possible as well with special software, but the standard Atari 8-bit 90kB format, which used FM rather than MFM encoding, could not be handled by the 1571 hardware without modifying the drive circuitry as the control line that determines if FM or MFM encoding is used by the disc controller chip was permanently wired to ground ( MFM mode ) rather than being under software control.

Another approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities.
