My 512Ke used never get noticeabley hot even when running for over an hour. However, I recently got a lovely 1986 Apple 800K drive (I hope to get a HD20 in the future). I have had using it almost 20 minutes when I noticed the top vent was far warmer than usual. I could feel the hear on my face from 10cm from the top. This was not the case before. My 512Ke is currently quite bested out in terms of peripherals. I've got external speakers, a LocalTalk adapter, a MacMan Midi Interface, the new external floppy drive, and of course the mouse, connected at once. Is this heat increase normal? Should I invest in a system saver thing?
