We could use such a floor in the UK at Bletchley should anyone have a line on one [1] that might become available. The ICL mainframe's going to have to sit on *something* and we're not quite sure what yet! [1] needs to be vaguely around 4m by 12m, but there's a bit of flexibility either way. I think 30cm high is about the max we can cope with though as we'd like to leave the suspended ceiling in place (and the ICL's I/O cabinets are full height racks) Have asked over on uk.comp.vintage, but I'm not sure how much readership overlap there is between there and here... cheers Jules
