IIRC the NMR spectrometer I worked around had a hard disk drive, the kind you loaded a stack of 12" (or so) platters into. Very Retro. The drive was on the far end of the console from the magnet. And watch out that the NMR doesn't suck the keys right out of your fingers. I heard stories about that. I did see one quench once, kind of spectacular. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting "I'm a designated driver on the Information Super Highway" --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
