[comp.sys.mac.hardware] Newer Mac Plus SCSI question

smisra@eos.ncsu.edu (SAURABH MISRA) (11/13/90)

I was told by a friend never to power up or power down
any SCSI device while the Mac is on.  (eg turning
on a SCSI printer when you are ready to print, and
turning it off when done, all the while the Mac is on)
I have a Mac Plus (the newer ones with the lighter color)
and I was wondering if this was true or not and if it
is what damage, if any occurs?

Thanks
