All: I had some time today so I started scanning a few random articles I had lying around. Back in 1988, Ed Roberts published a series of articles in Radio-Electronics for a stackable Z80-based industrial-like computer system called REACTS 7000. I seem to have most of the articles but I wondered if anyone on the list maybe has the original design packet you could order from Ed?s company, or any other info on it. As I find these random kind of systems, I?m putting together resource pages on my Web site for them (The Hawthorne 68k and the LittleBoard/186 are recent examples). So, if anyone has any info on this system, let me know. Thanks.
