My SE/30 manual (I know, the IIcx probably uses more) claims 75 watts max. So, an SE/30 costs at most: 75 watts * 24 hours/day * 30 days/month * 1/1000 watt/kilowatt * .10 dollars/(kilowatt*hour) = 5.40 dollars/month (Our electric rates are $.13 per kilowatt-hour in the summer. In the winter, they're about half that; $.10 is a ball-park average.) -- Steve Dorner, U of Illinois Computing Services Office Internet: s-dorner@uiuc.edu UUCP: {convex,uunet}!uiucuxc!dorner

I have a IIcx with the in-fa-mouse Quantum 80 Meg drive. I also run a Syquest (Micro Tech) unit and a CD-ROM drive. All of these are powered 24 hours a day. I turn my monitor on and off as used. From my electric bill changes over the past 5 years I have estimated that The setup uses $1 of electricity a day. However I do not know what my local rate is. As a side note I have not had a single problem with my Quantum drive. The CD-ROM on the other hand has been in for repairs three times. The last time they unpluged the fan and just last night it was not working again. :-( Also cover the floppy slot on your IIcx or you can destroy your FDHD. Mine started to reject a lot of disks so I took it out and it looked like fungus was growing in it. Pete Hoch

I suspect the display is most of the power and I turn it off. (It is rated for 15A. So if 1.6KW (110V*15A) at $0.12/(KW/H) = $0.20/H.) Jack
