I'd be interested in a Z280 system. I have a few of the jlead (socketed format) chips of very late revision I've built around. The design work I used was started by Tim Olmstead. The RSX system would likely run very well as Z280 offers larger memory, I&D space, supervisor/use, and MMU so a real protected space OS is possible. Allison
