[comp.arch] Using the SCSI interface

bill@bcsfse.UUCP (Bill Sears) (08/24/87)

    I have two computers each with a SCSI interface.  I am interested in
connecting the computers using the SCSI interface and I need some information
on what is needed to accomplish this (or if it is even possible).  I am mainly
concerned about the complexity of the hardware needed.  I am an experienced C
programmer so I am not too worried about the software side (although maybe I 
should be :-).
	I would appreciate any direct help or reference material.  Please respond
via E-mail or netnews (I have cross-posted this article but followups probably
should not be).
	If it is necessary, the machines involved are:
		1)  Amiga 1000 (I understand that a SCSI interface is available and
			will probably upgrade to 2000 soon anyhow).
		2)  Megadata 8300-7  (A 68000 based UNIX system V box).

Some time ago, Bill Sears (bill@bcsfse.UUCP) asked about connecting
two computers together using a SCSI interface, wondering what sort
of hardware would be needed.  While I'm not a scsi expert, my understanding
is that all you would need is a cable between the two systems and controller
firmware that can handle the communication.  The controllers would have to
be able to act as both initiator and target.  (In the scsi universe, the
<initiator> requests an operation and the <target> carries it out.)  Once
the hardware, controller, and device-driver needs are taken care of, you can
build your favorite network model without significant (scsi-specific) effort.
You can also have disks or additional processors on the bus, up to it's limit
of seven or eight (I forgot which).
