1348.0. "ST277R usuable with 1040STf?" by DETOO::HEARN (Time will tell...) Fri Jan 22 1993 10:17

    
    	Would anyone know if a ST277R can be used with the Atari
    	1040ST?  I have one and would like to use it if possible
    	(currently running a ST277N with Berkley MicroSystems 200
    	SCSI controller).

1348.1N stands for SCSI, R stands for RLL?COMET::CARPENTERSun Jan 24 1993 07:424
    While you can use a ST277R with the Atari I'm pretty sure it's not a
    SCSI drive so you would have to find an RLL driver for it from Supra or
    some other source that deals with MFM and RLL drivers and Atari Host
    Adapters.
1348.2St277 is RLL...DETOO::HEARNTime will tell...Mon Jan 25 1993 07:588
    
    Yes, the ST277R is RLL - also ST506/412 is the "interface" listed
    by Seagate.  Am I remembering correctly that the ST's Hard Disk
    interface is ST506? (or am I just wishing  :^)
    
    						More thoughts?

1348.3It was built into some MF60FRUST::EDDF10::ECKELNo sports.Thu Jan 28 1993 03:477
    Yes, the ST277R is RLL, and it indeed _is_ useable with the 1040. The
    drive was built into a number of MEGAFILE 60 units. 
    
    I exchanged it against a SCSI drive some months ago, sold the drive,
    and still have the controller lying around somewhere.

1348.4Is there hope?DETOO::HEARNTime will tell...Thu Jan 28 1993 07:169
    
    Peter,
    
    	I'd be willing to talk to you about the controller if you're
    interested, but it sounds like you either use SCSI or RLL.  Am I
    understanding that correctly?  I'd like to use them both (my SCSI
    *and* the RLL).  Is this possible?

1348.5Yes, RLL and SCSI work together.FRUST::EDDF10::ECKELNo sports.Thu Jan 28 1993 09:2421
    Hello Rich,
    
    with a recent version of AHDI, there are no problems using a RLL and a
    SCSI Disk at the same time, you only have to select different ID's for
    the ACSI controller than for the SCSI devices. Internally, most SCSI
    host adaptors for the ST simply translate ACSI signals to proper SCSI
    (ACSI is Atari's poor man's version of SCSI - nearly compatible, but
    not quite...). When I changed my disks from RLL to SCSI I did just that
    to get my data to the new ones. I use an ICD host adaptor for SCSI.
    
    Please send mail to me at DEC or to my Internet address 
      
      [email protected]
    
    about the controller. If you use the IN address, please allow one to
    three days delay, because it's a private dialing network that
    exchanges mail only once a day. At the moment I am not always in the
    office, so there may be some delay using the DEC account, too.
    
    Regards, Peter.

    Peter,
    
    	We'll continue about the controller "off-line" via MAIL.
    
    	Thanks for the information presented here - I'm sure others
    	will be able to use it too.
