Adding a drive to an ESM

[Brendan Kehoe]

I'm trying to figure out how to add another drive to my system. I have an
External Storage Module that has one 150Mb tape and one CDC Wren IV 327Mb
drive in it. It's got a half-height slot that's screaming to me to be
filled. And since my current space situation is rapidly dwindling, I
decided to check out how much it'd cost to add a drive.

I found a Seagate ST296N 28ms 84Mb SCSI drive for $330. But this little
voice in the back of my head's saying "cables .. cables .. cables". So I
decided to listen to it & check out the inside of my ESM.  The cabling
looks a little weird, but I figured out how it goes:

		SCSIport:--------drive--+
		                        |
		SCSIport:--------tape===+

The hard drive's cable is "stacked" onto the tape's one at the tape, then
one cable goes out from the tape drive to the bottom scsi port, which has
the terminator on it.

So, my question is, if I insert that other drive into the bottom
half-height part of the ESM, how easy will it be for me to take the line
going from the tape to the bottom scsi port, and instead bring it down to
the 2nd disk drive, and have the 2nd disk drive's cable run to the bottom
scsi port? e.g.:

		SCSIport:--------drive--+
		                        |
		                 tape===+
		                        |
		SCSIport:-------drive2==+

Is it simply a matter of getting another one of those "stack" things and
another ribbon cable?  Thanks .. please excuse my ignorance on alla this;
I haven't played with the hardware much yet.
