I often get fatal system error 0308. Does anyone have any idea what this is? It most often occurs when running graphics programs. Thanks, Rocky Giovinazzo

Have you ever gotten an error $681? This is also a good indicator. If you *do* have a fan, then you'll need to keep the case propped open. My GS is *extremely* heat sensitive (the TWGS doesn't help much). On these warm summer days I have to totally remove the top off the GS so it will even run. I am also using an internal fan, but even it doesn't help much on the hot days. -- ++------------S-U-P-P-O-R-T---S-H-A-R-E-W-A-R-E---O-R---D-I-E-!-----------++ || Tim Meekins || Snail Mail: || Apple II || || meekins@cis.ohio-state.edu || 8372 Morris Rd. || Forever! || \\___timm@pro-tcc.cts.com________/\____Hilliard, OH 43026__/\_____________//

Meaning something went wild and changed some part of memory that it had no business messing with. It could *conceivably* be bad RAM chips, but most likely it is a software problem. Try to narrow down the problem--does it only happen with a few specific applications? Try removing any third-party desk accessories or setup files and see if that has any effect; if it does, put them back one at a time and maybe you can determine which one is misbehaving. "Flaky" problems like this are hard to pinpoint sometimes, because just removing something could make the problem go away "by accident", just by changing the relative positions of things in memory. -- David A.

This seems kind of strange-- I've got a system saver GS fan and the only cards I have are a stereo & memory card. Does the GS really eat up enough energy to cause this problem? Rocky Giovinazzo

I just had work done on my machine a couple months ago and it apparently passed whatever diagnostics the dealers run. I assume the diagnostics check for bad RAM chips? Rocky Giovinazzo

Version 2.0 of the gs diantostic disk (Apple's) does have a test for RAM chips. The interface is a little awkward but presumably a trained repairman can use it effectively. I am not sure, however, if the results of the various diagnostic tests are always valid. The date on the disk is 1986; doesn't that predate the ROM 03?

Does the GS really >eat up enough energy to cause this problem? The answer is yes. I too was getting error $0308 with only a memory card and a modem. I added a fan (AE's Conserver) to the system, and I had no more problems. I also have the built-in fan of the Vulcan HD I have installed, so heat is no longer a problem. I have a question, though. Because I have my monitor sitting on top of the computer, all the excess heat that the fans draw from the interior of the computer is now going into the monitor. Can this cause a problem?
