typical ieee standards start with a company building a device, and then submitting it to the ieee for the standardization effort. in the case of futurebus this was reversed, the whole system was being designed during the standardization effort. this proved to be its downfall. as companies came to see futurebus as "the" system, they all joined in. soon the standards meetings had hundreds of people attending, all of them demanding that their particular needs and wants be included. as the complexity grew, the standards process slowed. in the end it took eight long years before the specification was finally agreed on in 1987. tektronix did make a few workstations based on futurebus. american logic machines (alm) continues to build end to end system futurebus hybrid solutions, including vme-to-futurebus+ and other bus-to-futurebus bridge technologies.
