HELP! anyone know Apple ///'s??

[thompson1371@iscsvax.uni.edu]

Got a quick and easy question for anyone owning or ever having used an
Apple ///...  I recently acquired the cpu (sans monitor and power cord)
from an auction, and it seems to work well on my //c's monitor.  I cannot
seem to remember the steps necessary to throw it into Apple II emulation
mode.  I don't have any SOS disks, so I cannot even boot it up.

Thanks for the help!

(any other helpful info on quirks of the /// would also be appreciated!)
