We are looking for a high speed parallel interface for our DN10000 to allow it to connect to our Alliant FX/8 for an application involving real-time simulation of mechanical systems. The application will not require high bandwidth, but will require fast (sub-millisecond) response. Our Alliant can support the Gould HSD interface. I've checked the HP/Apollo Products Price Guide and can find no mention of any high speed parallel interface (surprise! surprise!). Has anyone heard of a third party device that would fit the bill, or perhaps, an unannounced HP/Apollo product along these lines? Please respond via e-mail and I'll summarize. -- Timothy VanFosson E-mail : timv@ccad.uiowa.edu Senior Systems Analyst US Mail : CAD-Research University of Iowa 228 ERF Phone : (319) 335-5728 Iowa City, Iowa 52242

I am reposting this because of some problems I had with relaynews, so I'm not sure the original got through. Forgive me if I'm wrong. We are looking for a high speed parallel (or higher speed serial) interface for the Apollo DN10000 (VME) that will allow us to communicate with our Alliant FX/8, (presumably, such an interface would have to work on the Alliant as well). Bandwidth is not critical(>200Kb/s is ok), but latency must be minimized. The application is a real-time, mechanical systems dynamics simulation coupled with real-time, realistic animation of same. The dynamics would be run on the DN10000, with other host functions carried out on the Alliant FX/8, which will communicate with a high-end image generator. Sub-millisecond latency is preferred, as we must maintain ~15 millisecond intervals for data transfer to the image generator. Essentially, what would we be looking for is something like a DR11 or HSD interface. If anyone has experience with such and interface, or has seen one advertised, I would appreciate a pointer.
