Please forgive me if I'm causing a rehash of the recent discussion on
larger disks for the 3B2.


Here's my problem...

We were recently given (loaned) two used 3B2/300's for use in various
research work. One is equipped with a 30meg disk which is adequate for
its intended application.

The other 300, however, is only equipped with a 10meg disk (it must have
originally been on a networked file system) which is woefully inadequate
for its intended use.

When my Director checked with AT&T about the availability of a lager
capacity drive, they suggested two options:

	1) Add an expansion box at approx. $9000

	2) Purchase a SCSI interface and use it to hook the
	   300 to a spare CDC 80meg washtub we have. (~$4000)
 
As a result, I am left with several questions of my own:

	1) Can you really hook a CDC washtub up to a SCSI interface?
	   If so, will you need any extra hardware/software.
 
	2) Why can't the 10meg in the 300 just be replaced with
	   something larger (like a 70meg Priam)? Is there some
	   limitation to what the controller can handle?

	3) If you can just drop in the larger (SASI?) drive, then
	   what hardware/software changes will need to be made?


Any information would be appreciated.  Thanks in advance.
