I'd say they're worth having if you have space and can transport them (pretty heavy beasts). You may be lucky enough to get an ethernet controller or two as well - I gather that these aren't too common - then they'll hook up to just about anything. Oh, if you get a chance can you see if there's any OS tapes lying around?? I haven't got installation media for my 700 so when one of the disks goes I'm in trouble... I'm not sure how NCR shipped OS tapes and whether one tape would cover a series of Tower systems or not... cheers Jules
