  INMOS Transputer
A typical desktop machine might have two of the "low end" Transputers handling I/O tasks on some of their serial lines (hooked up to appropriate hardware) while they talked to one of their larger cousins acting as a CPU on another.
Transputers could be booted over the network links (as opposed to the memory as in most machines) so a single Transputer could start up the entire network.
While the Transputer was simple, but powerful, compared to many contemporary designs, it never came close to meeting its goals to be used universally in both CPU and microcontroller roles.

 Amiga Transputer
The Amiga Transputer was proposed by Tim King (who had previously ported TripOS to the 68k) and several others at Metacomco.
What I know of the transputer is that it was demoed at the spring 1988 developer's conference in an off the shelf A2000.
If the developer is to be believed, the Transputer would have offered 'up to 40 times the performance of a 68040 when fully loaded with transputers'.

  Smart Computing Encyclopedia Entry - transputer   (Site not responding. Last check: )
The transputer was originally developed and bundled with Occam, an advanced parallel processing language, but ultimately migrated to use with C, where it garnered more widespread adoption.
When the 30MHz T9000 transputer arrived, it featured superscalar architecture, a 64-bit floating point unit, 16KB on-die cache, and a revamped communication process wherein the serial links communicated via a packet-based protocol rather than byte-based, with each packet being 32 bytes plus a header to direct the packet’s routing.
Naturally, transputers had the advantage of running in large-scale, parallel processor configurations, but mounting advances from Intel, IBM, and other microprocessor vendors sealed the transputer’s fate.

  Parallel Programming In C For the Transputer.
Its target is the Inmos transputer, a RISC processor with networking capabilities which has gained a good reputation in Europe and is now becoming increasingly popular in the United States.
I chose the transputer because it offers good cost/performance trade-offs, making it attractive for small computer science or computer engineering departments, as well as for individual and/or engineers interested in faster processing speed for their PC, MacIntosh, or work station.
This is followed by a presentation of the architecture of the transputer, a RISC processor augmented with on-chip memory and four ports, allowing various network topologies (Chapter 2).

The Atari Transputer Workstation (also known as ATW-800, or simply ATW) was a workstation class computer released by Atari in the late 1980s.
Based on the INMOS transputer, the machine was considerably more powerful than anything available on the market at the time.
Of particular note was the lack of memory protection, due largely to the lack of an MMU on the transputer.

 A Replacement Transputer Node for the Agora Distributed Computing Architecture for Robotics
A Transputer is a processing node with local memory and resources, which communicates with other Transputers via high-speed dedicated serial links.
Transputers are designed to be connected in homogeneous networks, where all communication between nodes is performed over these links.
The Transputer links are routed off the board with a standard wide-pitch connector, and pass through an adapter board on to the existing robot.

 An Implementation of Real-time Granular Synthesis on a Multi-processor Network (main body)
Four transputers form a single element and four of these are situated on a single 3U printed circuit board, 16 transputers in total.
For the revised configuration, a transputer with 128k- or 256k-byte of external memory is connected to three transputers at the tree-bottom level that share this extra memory.
At a moment, 9 of these transputers with external memory are available that cover a third of the network and provide at least 27 voices.

 WoTUG - Transputer
The INMOS Transputer was a pioneering parallel computing processor of the 1980s from the Welsh chip design company INMOS.
The "lower" nibble contained data, either for arithmetic operations, for addressing memory, or as an operand to the indirect opcode, which was used to add more instructions to those available using the the 16 possible using a nibble.
One big advantage of this scheme was that it permitted 16 bit and 32-bit transputers to share the same binary format and, in many cases, the same compiled programs.

 The Transputer Connection: Atari and Perihelion
Tim King, the president of Perihelion, is as warm and friendly as the unusually sunny British summer afternoon on which we interviewed him.
This is all taken care of at the 68000 end, leaving the Transputer free to handle the heavy stuff." King points to the open guts of an ATW nearby.
Each of these daughter boards has three Transputers on it, and the ATW can hold a total of four boards which means 13 Transputers, all working at once at 10 MIPS [Million Instructions Per Second] and using some 16 megabytes of RAM.

In the late '80s, while I was living in Madrid, I was lent a prototype of the Atari Transputer Workstation (ATW) (known at the time as the Abaq).

 tForth: Forth for the Transputer
Considering the fact that a transputer context switch is in effect a change of the workspace, we decided to put all of the Forth administration in the workspace.
A transputer Forth conforming to the Forth 83 standard is a bad idea, as that explicitly requires the use of a 16-bit model [9].
To a transputer a cell is not equivalent to four bytes in a row, as a cell address should be a multiple of four.

 AEX - The most comprehensive exploration of Atari online
Transputer technology had been advanced through Inmos (now part of SG- Thompson), a company largely responsible for the commercial success of the T-400 and T-800.
Transputers had been largely unsuccessful commercially, mostly due to the price and the lack of any mainstream support for the product.
Initial reports mentioned development of an "ST Transputer" or add-on board for the the current ST range, but this would be just rumour, the fact was Atari had been developing a very niche product in conjunction with Perihelion, another UK based company.

 Gemini Twin-Arrays Infrared Camera User's Manual: More About Gemini
The transputer is a microprocessor with on-chip RAM and four high-speed serial links which allow it to be easily networked for use in parallel applications.
One transputer (the "root" processor) is situated on a PC-bus card in our host computer where it receives commands from the PC, passes them over the serial links to the three front end subsystems: the long-wavelength (fast) channel, the short wavelength (slow) channel, and the stepper motor controller.
The stepper motor control transputer accepts commands from the root transputer and feeds the required pulses to stepper motor driver chips to move the various mechanisms in and around the camera.

 Parallel Computing Using Transputers
The transputer is a family of microprocessors developed by Inmos, Ltd., a member of the SGS-Thomson Microelectronics Group (transputer is a registered trademark of Inmos).
The T4 and T8 series transputers were developed in the mid-1980's and are 32 bit processors comparable in speed to Intel 386 and 486 processors.
The transputer was designed hand-in-hand with the language Occam, a language for message-passing parallel processes based on Hoare's CSP (Communicating Sequential Processes).

The transputer is halted by asserting MemReq and waiting for the transputer to reply with the assertion of MemGranted.
Also the transputer’s autonomous links can slice data into the display allowing the frame store data to be derived from a network of transputers.
With this powerful feature, for example, a transputer graphics board could become a graphics command interpreter, receiving commands via links (fast graphics primitives residing in internal RAM), or an intelligent frame store connected to large computing engines built from arrays of transputers, which pump data straight to the frame store via the four INMOS links.

 EVIDENCE GROWS THAT INMOS TRANSPUTER IS CLOSE TO MARKET BREAKTHROUGH - CBRonline.com
Proof of market acceptance of the Inmos T800 Transputer is coming thick and fast now that it has entered volume production at Inmos International's Newport, South Wales fabrication plant.
With Atari Corp now a committed fan, and with strong hints that Steve Jobs' Next Inc may be planning to use the part in its Scholar's Workstation, the Inmos part can be said to be on the brink of breakthrough.
But all the Transputer developers at Compec agreed that the advent of widespread parallelism in computers would necessitate a new awareness of how to exploit it from programmers.
