Okay, 1990 wasn't that far back (at least I tell myself that every day). These always start out the same way... So I purchased a Macintosh Classic (September 1990) hoping to find a way to get it online and maybe even show my son when he is old enough to understand computers. I don't know... it seemed like a good idea at the time. Anyway, like most e-bay computer purchases, it doesn't work 100%. I'm not really sure what % it does work, but I thought I would post it and see if anybody has any suggestions other than turning it into a fish tank. Computer powers on Happy Mac Appears Welcome to Macintosh screen shows BOOM!!! Sorry, a system error occurred. error type 41 To temporarily turn off extensions, restart and hold down the shift key. So... click restart... hold shift I get Happy Mac Welcome to Macintosh Extensions OFF screen shows BOOM!!! Sorry, a system error occurred. error type 41 To temporarily turn off extensions, restart and hold down the shift key. and the vicious cycle begins Unfortunately, the first computer I purchased after college was a 266mhz PowerMac Desktop, so I'm not really sure where to begin with this one. If anybody can point me in the direction of some already documented online help, that would be great. I don't mind sifting through webpages to find answers. I just have had any luck with my searches so far. Thanks!
