Problem: I want to put together a PC-based control system that will acquire data, digitally figure out what the feedback should be doing, correct the control signal, and send it out to the plant. The system should operate at 100 kHz or better. Query: does anyone know of an add-in board I can buy that will make this easy and quick to do? I know I can build my own from the chips up using a DSP, A/D's and D/A, ROM, and RAM. However, if I can find an easier and faster way to do it, I'll take the fastest way. I've looked at a few data acquisition boards that are used to log data or control slow processes (e.g., temperature controllers) but I haven't seen anything like what I want. -- Kerry Yackoboski <yackob@eeserv.ee.umanitoba.ca> The Scanning Tunneling Microscopy Laboratory in the Cellar U of Manitoba, Winnipeg, Canada

It uses a DSP32-8 MFLOPS C and FORTH ( Rapid Prototyping Language ) and include math and DSP libraries from AT&T. Comes with the compilers, and buffered serial interface. Codec plug-in boards go from 8 to 16 bits. They can be reached at (303) 693-3413 15874 E. Hamilton Place Aurora CO 80013
