Sound Blaster AWE32

Sound Blaster AWE32

The Sound Blaster AWE32 was an ISA sound card released by Creative Technology in March 1994. It was a nearly full-length ISA sound card, measuring 14 inches (356 mm) in length.

The AWE32 included two distinct audio sections: the Creative digital audio section with their audio codec and optional CSP/ASP chip socket; and the E-mu MIDI synthesizer section. The synthesizer section consisted of the EMU8000 synthesizer and effects processor chip, 1 MiB EMU8011 sample ROM, and 512KB RAM. The RAM was expandable to 28MB. These chips comprised a powerful and flexible sample-based synthesis system, based on E-mu's high-end sampler systems such as the E-mu Emulator III and E-mu Proteus. The effects processor generated various effects (i.e. reverb and chorus) and environments on MIDI output, similar to the later EAX standard on Live! and newer cards. It could also add effects to the output from the Yamaha OPL-3's FM synthesis. The AWE32 was the first sampler to support E-Mu's SoundFont standard, which allowed users to build custom sound sets using their own samples, the samples included in ROM, or both. The card included software for building custom SoundFonts. All of Creative's subsequent cards, other than the Sound Blaster PCI64/128 series, support SoundFonts.

 
Mountbatten Brailler

Mountbatten Brailler

The Mountbatten Brailler is an electronic machine used to write braille. The Mountbatten incorporates the traditional "braille typewriter keyboard" of the Perkins Brailler with modern technology, giving it a number of additional features such as word processing, audio feedback and embossing. The machine was pioneered and developed in 1991 at the United Kingdom's Royal National College for the Blind in Hereford by Ernest Bate.

Initially the Mountbatten was manufactured in Australia, with 3] On January 1 2010 manufacture of the Mountbatten was taken over by Polish company Harpo Sp. z o. o.[4]

Like the Perkins, the Mountbatten has a key corresponding to each of the six dots of the braille code. By simultaneously pressing different combinations of the six keys, users can create any of the characters in the braille code. In addition to these six keys, the Mountbatten has a space key, a backspace key, and a new line key. Like a manual typewriter, it has a knob to advance paper through the machine, although unlike the Perkins the bar does not move. There is a Return key rather than a carriage return lever.

In addition to the traditional keyboard, the Mountbatten has several other features. These include memory which allows braille text files to be stored in much the same way as is done with a word processor, speech feedback allowing the user to listen to the text they have just typed or from files, and forward and back translation between text and braille. The Mountbatten can be connected to a printer allowing files to be printed as text, while a regular PC keyboard can be connected to the Mountbatten enabling text to be produced as contracted or uncontracted braille.

Atari Stacy 2

Atari Stacy 2

Originally announced in 1987, the Atari Stacy was released to the public in December 1989. It was the first portable Atari ST computer and was available in three different configurations:

  • Stacy: 1MB RAM, 3.5" floppy disk drive
  • Stacy 2: 2MB RAM, 3.5" floppy disk drive, 20MB SCSI hard drive
  • Stacy 4: 4MB RAM, 3.5" floppy disk drive, 40MB SCSI hard drive

The 12 C-cell batteries it was designed to run on proved to be insufficient for running longer than about 15 minutes. Coupled with the 7Kg weight, the Stacy was not a great commercial success. Around 35,000 units were shipped, and the model was discontinued in 1991.

CW/P Cortex

CW/P Cortex

The Cortex computer was manufactured by the British company C/WP ("Computers and Word Processors"), who bought the design from the US company Ontel (they marketed it as the Amigo). Major modifications were made to the hardware, including easy service access, and software, all designed to make this micro more user friendly. CW/P was aiming to sell the system to the mainstream office word processor market.

The Cortex was in three main parts: the keyboard; 5.25" disk drive; and monochrome display, which also housed the main logic board. The plastic housing was available in six different colours. Only four screws needed to be removed to access change any part of the system.

The IBM-style keyboard was set up to generate various Wordstar control codes, and the version of WordStar shipped with it was modified to use them. It ran the CP/M operating system, modified to support a second processor for display management and graphics capabilities. It was also one of the first machines to support Digital Research's GSX graphics standard.

Elektronika MK-52

Elektronika MK-52

The Elektronika MK-52 (Russian: Электро́ника МК-52) was an RPN-programmable calculator manufactured in the Soviet Union during the years 1983 to 1992. Its original selling price was 115 rubles.

The functionality of the MK-52 was identical to that of the Elektronika MK-61, except that the MK-52 had an internal non-volatile EEPROM memory module for permanent data storage, a diagnostic slot, and a slot for ROM modules. The programming language and functionality of the MK-52 and MK-61 calculators were extensions of the earlier MK-54, the B3-34, and B3-21 Elektronika calculators. The MK-52 is the only calculator known to have internal storage in the form of an EEPROM module. All Soviet calculators are renowned for having a very large number of undocumented functions.

The MK-52 was used as a backup to onboard computers of the Soyuz spacecraft during the Soyuz TM-7 mission to the Mir space station.

In what would be considered an unusual practice today (but was common for Soviet electronics), technical schematics were provided for the MK-52 when it was purchased, prompting user modification and repair of the machine.

SGI Indigo 2 Impact

SGI Indigo 2 Impact

Released in January 1993, the Indigo 2, codenamed "Fullhouse", was the successor to SGI's Indigo workstation.  The Indigo 2 was marketed as a high-end workstation, with many configurations totaling well over $100,000 (USD), and thus was placed above the “budget” SGI Indy workstation released several months later. Like any other SGI workstation, the Indigo 2 was mostly used in academic and commercial settings, with very little value or use to the personal computer market. 

Classifying specific specifications is made difficult by the highly customizable nature of SGI’s workstations.  This issue become even more convoluted by the 1995 release of the Indigo 2 Impact. Like the Indy, the Indigo 2 and Indigo 2 Impact belong to the group of colourful and iconic “pizza box” workstations meant to fit underneath a monitor. Both versions are easily differentiated by the colour of their case with the base Indigo 2 teal and the Indigo 2 Impact purple.  There is also an additional rare POWER Indigo 2 version which featured a R8000 processor in a teal case.

The Megaprocessor

The Megaprocessor

The Megaprocessor is a microprocessor built on a huge scale.  It consists of seven panels, is two metres high and nearly ten metres end-to-end.  It was built by James Newman, of Cambridge, as a hobbyist's project.  Since the Megaprocessor is not based on any single computer or chip architecture, it is a unique machine, the only one of its kind in the world.  It arrived at the Centre on 20 October 2016 and is currently on display in the foyer.

The project began with Newman's desire to learn about transistors.  The transistor is the fundamental component of modern electronics.  It switches or amplifies electrical power, allowing for the creation of logic circuits.  Today they are mostly produced in integrated circuits, with millions or billions of them crammed onto a microchip.  Newman used discrete transistors: individual components you can count in the palm of your hand.

This makes the Megaprocessor a huge recreation of a device that, in practical electronics, would be tiny.  The advantage of this approach is educational.  Newman said:

“Computers are quite opaque. Looking at them, it’s impossible to see how they work. What I wanted to do was get inside and see what’s going on. Trouble is we can’t shrink down small enough to walk inside a silicon chip. But we can go the other way; we can build the thing big enough that we can walk inside it. Not only that we can also put LEDs on everything so we can actually see the data moving and the logic happening.”

The Megaprocessor runs at a top speed of around 20khz and can be slowed down to 0.01hz.  Programs can be halted and stepped through cycle by cycle.

256 bytes of RAM is included on a separate panel, with each bit represented by an LED.  The board is approximately 2m2.  On this scale, 32GB of RAM - a commonplace amount in performance PCs -  would need a panel the size of the United Kingdom.

There are over 10,500 LEDs and 40,000 individual transistors on the system.  Newman made more than a quarter of a million solder joints during construction.

For more information on the Megaprocessor, please visit Newman's site, www.megaprocessor.com.

Mark XIV Bomb Sight

Mark XIV Bomb Sight

The Mark XIV Computing Bomb Sight was a vector bombsight developed and used by Royal Air Force Bomber Command during the Second World War. The bombsight was also known as the Blackett sight after its primary inventor, P. M. S. Blackett. Production of a slightly modified version was also undertaken in the United States as the Sperry T-1, which was interchangeable with UK-built version.

Developed in 1939, the Mk. XIV started replacing the First World War-era Course Setting Bomb Sight in 1942. The Mk. XIV was essentially an automated version of the Course Setting sight, using a mechanical computer to update the sights in real-time as conditions changed. The Mk. XIV required only 10 seconds of straight flight before the drop, and could account for shallow climbs and dives as well. More importantly, the Mk. XIV sighting unit was much smaller than the Course Setting sight, which allowed it to be mounted on a gyro stabilization platform. This kept the sight pointed at the target even as the bomber manoeuvred, dramatically increasing its accuracy and ease of sighting.

The Mk. XIV was theoretically less accurate than the contemporary Norden bombsight but was smaller, easier to use, faster-acting and better suited to night bombing. It equipped the majority of the RAF bomber fleet; small numbers of Stabilized Automatic Bomb Sights and Sperry S-1s were used in specialist roles. A post-war upgrade, the T-4, also known by its rainbow code Blue Devil, connected directly to the navigation computer to automate the setting of windspeed and direction and further increase accuracy. These equipped the V Bomber force as well as other aircraft.
