2984.0. "Q] Extend existing SCSI2 chain or buy new cable?" by FREE::CAMBRIA (Still worrying about deck chairs) Thu Apr 10 1997 15:41

I just bought a new internal SCSI2 Tape Drive.  The cable that came with 
it only has 3 connectors on it.  This brings up a stupid question.

Is there a way to extend an existing SCSI2 internal cable?  I would like 
to simply add a new internal device to the existing chain, but the 
current cable just has 3 connectors; the 2940 controller at one end, 
the CDROM at the other end with a disk in the middle.  As I said, the 
tape drive came with a similar cable.

Is there a way to "extend" the current cable or do I have to go out 
and buy an new one?

Thanks for any insight.

    I'd recommend to buy a new one. Maybe with another spare connector.
    These internal SCSI cables sell for ~$15 thru mailorder. I tried to
    attach some additional 50-pin connectors myself with lesser success.
    But should be possible too with the right cramping tool and keeping
    the required distance between connectors (~0.3m?).

    If in fact the cable would be long enough to reach, and you have access
    to a bench vise, it's a fairly simple matter to crimp on an additional
    connector (which your local RatShack probably has).
    
    Otherwise take a trip to a ma/pa computer shop (eg: PC Warehouse, etc)
    and pick up a 5 position internal cable.

    I have an internal extension cable (purchased at a PC show from a
    surplus goods dealer).  Works ok.  I agree with the reply that suggests
    that you get another cable.  Much cleaner.

Me thinks there are specs that cover the (minimum) distance between two
adjacent connectors.  To not follow them might result in spurious problems
during heavy operations.
