[comp.sys.ibm.pc] Help: Adaptec 270A & 2nd hard disk

dd@beta.UUCP (Dan Davison) (05/25/88)

I currently have a Seagate ST238 with an Adaptec 2070A controller,
and I'd like to add a second hard disk.  There are no obvious jumpers
on the board but there is an obvious second set of pins for a "B"
(probably data) cable.  The "A" (thicker) cable presently only has
one 30+ pin card edge connector.

My question is this: how do I add a second hard disk to this
configuration?  I assume I have to replace the "A" cable and
get a "B" cable, but is there anything else?  I have a number
of drives to chose from so I'm not worried about compatibility.

If possible, please reply by e-mail; I tend to get behind on this
bboard.  

(The "A" and "B" cables refer to the standard SMD disk cabling; I
have no idea what the PC world's names are for the cables).

Thanks in advance.
