Yes, you can add SCSI peripherals to any model 3B2 with the appropriate
hardware and software.  Although, this was never tested on a 300, I know it
works because I have done it.  The problem comes with support, since it was
never tested, it is not a supported configuration.

Probably more than the 3B2/300 is worth.

Look in the computer rags.  Some companies do sell used 3B2 equipment.

Yes, and you will also be able to add drives just by cabling them on the
end of the bus.

The current releases of UNIX are paging releases.
Your best bet is using Release 3.2 if you are going to try this adventure.

Your best bet is to forget adding this to the 300 and consider a 3B2/500 or
600.  You'll get all the hardware you need standard, a better OS, and an MAU,
better memory expansion and a tape drive for backups all standard.
