Is anyone aware of any digital signal processing boards for the Mac II or Mac IIcx? I need to do 512-point Fourier transforms in under 10 milliseconds. Bill Lipa

Spectral Innovations at (408) 727-1314 in Santa Clara, CA offers a MACII board with a AT&T DSP32 on it with data acquisition hw and analysis sw. I have no experience with it and am just quoting from AT&T promotional literature. apple!jrg John R.

It is based on the Motorola 56001 (same chip as the NeXT uses) and seems very well designed. The technical specs claim "1024 point FFT < 4 ms." There is an article by the board designers in the current issue of Computer Music Journal. Digidesign offers developer discounts and provide utilities to integrate DSP code into your Mac programs. I recommend checking it out. Digidesign 1360 Willow Road Ste. 101 Menlo Park, CA 94025 (415) 327-8811 I have no affiliation with the company and I own one of the boards. Roger Corman
