requirements specification | ![]() |
Chances are, you know your needs. But can you state them clearly and completely? Teatronics Inc. gave us a general description for a high-end stage lighting control system. We turned this into a detailed specification of the LD series of lighting control consoles. Eighteen months later, the finished product matched our original spec. | ||
![]() For Teatronics Inc., we've designed a highly integrated processor for the Producer II+, the Comstar/MD288 control processors, and a scalable multiprocessor system for the LD series control consoles. |

PCB layout | ![]() The board on the right is Starr Labs' original board. Our "D5" design, on the left, has four times the memory, four times the I/O capacity, and is 40% smaller. We've also designed PCBs for Teatronics' LD series and Producer II+, for the McMaster Tandem Accelerator, and for our own SM-II multiprocessor. |
|||
![]() To automate the McMaster Tandem Accelerator, we built a complete prototype of a multiprocessor control system, using off-the-shelf SBCs and our own interface boards. Shown here is the three-processor control nucleus, installed in the equipment rack of the Tandem Accelerator. |

software design | ![]() For Altech Controls, we designed a distributed object-oriented language for their BACnet(tm)-capable industrial controller. |

We
don't just design; we implement as well. We wrote the complete operating
software for the Teatronics Comstar/MD288 and the AI-based McMaster
Tandem Accelerator.
We also programmed major portions of the Teatronics LD series (system executive and user interface) and Quantum consoles, the Starr Labs EventStation MIDI controller, and Altech Controls' ANGL distributed control software. And of course, our own CamelForth programming environment is finding wide use in the embedded programming community. |

documentation | ![]() Some of our documentation is so good, it gets published. Look at the eight-part series on our CamelForth system, which appeared in The Computer Journal. And our three-part Forth Dimensions series describing the Chromium compiler has become one of the standard references on Forth metacompilers. |

"It's
a dirty job, but someone has to do it." Perhaps you've been left with some
"legacy" code, and the original author is no longer available. Forth Inc.
contracted us to maintain and update their
BMDSIM simulator package
for just this reason.
Or perhaps your technical staff is swamped with work. Teatronics Inc. hired us to convert their Producer II software to a new CPU, and later to adapt and extend this software to produce the Producer II+ and Quantum lighting control consoles. And we've developed point-of-sale terminal kernels to support Forth Inc.'s Open Terminal Architecture project.
