It seems relatively easy to exhaust the capacity of the MacIIx power supply. I appear to have done it with 4MB RAM, a Relax WrenV disk, a Supermac Spectrum8/II video card, a Tecmar NuLink tape card, and a National Instruments NB-MIO-9 multifunction data acq card. Does a power supply upgrade exist? Will adding another 4MB RAM significantly worsen the problem? Any ideas about what I can do with the three slots I cannot use?!#%! -- Joel M Miller Internet: jmm@skivs.ski.org Smith-Kettlewell Institute Usenet: uunet!skivs!jmm 2232 Webster St Bitnet: jmm%skivs.ski.org@uunet.uu.net San Francisco, CA 94115 Voice: 415/561-1703 Fax: 415/561-1610

In the PC universe, we'd get a bigger power supply. That hard drive isn't small; you could externally power it from a PC supply (I'm only half-joking). Alternately, you could comb the power-supply catalogues for a comparable supply of similar form factor. Power supplies are the great undiscovered gotcha in the Mac. Over in PC-land, we all got bit early and often by this one; even your 250-watt supply has no overvoltage protection, so it's *SNAP* everytime a component cooks. Unless you spend $180 on a PC-Cool or similar U.S. supply. Sorry, don't think they've gotten to Macses yet. Ask Sony--they make most of the Mac supplies. Alex
