I got an upgrade offer from them (postmarked January 9) with the following info: Advanced A. I. Systems P. O. Box 39-0360 Mountain View, California, 94039-0360 (415) 961-1121 My $.02: This is a great product. You get immediate compilation in a full debugging environment, so you get the speed of compiled code and the ease of debugging interpreted code. I got it for $150 when it still fit in 1/2 Meg; the latest release (M-2.0) costs $298 and requires 1 Meg. AAIS uses Edinburgh syntax, and C-Prolog or Quintus Prolog programs can be trivially ported to AAIS (I've done it). It has full toolbox support and access to foreign code. Not copy protected. They recommend 2 800K drives, or an 800K drive and a hard disk. This is a solid, professional product.
