I was never able to get my hard drive to spin down on my Color Classic server (I don't think the Mac OS 7.6.1 included that energy saving option for the CC) even when all of my applications were running off a RAM disk.
But I did make a banner for the http://colorclassic.com web site that's a take off on the Apple Internet Server Solution banners from back around 1996. If you happen to run a web server on your 68k Mac you're welcome to use it, too:
