REQUEST: IBM 9347 001 9 Track Tape Unit Information

Post by Clark Mil » Tue, 19 Jan 1993 19:31:43

Yippie!!!  I got a tape drive that takes 1/2" 9 track (I counted the
heads!) reels.  The unit was totally dead when I got it but by simply pushing
the power connector back onto the rear of the power switch (to simple to
believe!) all seems perfect.  You load the reel through a flip slot at the
front of the unit, press "Load Rewind" and the unit laces up the tape and goes
to the start of the tape and goes online, quite nifty.  Self tests come up ok
and as far as I can tell the unit is perfect.

System is dated late 1988 so isn't too old (I hope) and me having 400Mb HD
storage and no tape drive I was wondering if I can hook it up to my system.
[Backup?  What backup???]

First problem is to figure the interfaces on the rear of the unit, two DB50's
(They look like large RS232 ports with 50 pins) depicted below:

\   o o o o o o o o o o o o o o o o   /
 \   o o o o o o o o o o o o o o o   /    A1    (Male)
  \ o o o o o o o o o o o o o o o o /

\   O O O O O O O O O O O O O O O O   /
 \   O O O O O O O O O O O O O O O   /    A2    (Female)
  \ O O O O O O O O O O O O O O O O /

Does anyone know what type of interface this is?  Can it be used for/with
IBM-AT type machines or is it purely mainframe material (It comes designed for
rack-mounting).  Also there is a 3 switch dip switch for setting a binary
number [address?] from 0-7.  (scuzzie???)

Also there is a plug that looks like an Americal telephone type jack (RJ45?)

Note followups set to (Hope that's the right place for it)
or mail me.  If someone wants to fax me the manual, I won't tell :-)

All, any information greatfully received, I like this unit and would like to be
able to use it, it's neat!  BTW I run a 486 with Esix Sys V 3.2 which is very
similar to Interactive FYI.  Many thanks if you got this far...  clark

1. IBM 7203-001 Portable disc unit failures

A client of ours have a lot of trouble with disc failures on RS/6000 520
server machines. Each server has 6 external IBM 7203-001 (670MB) discs
handled by 2 SCSI-cards.

IBM says the internal 800+MB discs are not so reliable as the external ones,
but there has been a lot of disc-crashes on both types.

Is this a common problem ? Are there any reliable third-party disc available ?
