Get yourself a 'Y' power connector from virtually any clone shop. CBM is aware
of the 'missing connector', and you may see it supplied with the next batch of
power supplies.

I didn't terminate my second drive, and it works fine. SCSI termination is one
of those things that usually works when you follow the rules, and often works
when you don't. According to the SCSI spec, the internal drive should be
terminated, but in practice, a short run like this will usually work fine.

The mounting bracket for the power switch will contact the second drive if you
mount it too far forard. Other than that, no problem.

No.

No idea on prices. I replaced the Quantum 40 with a Quantum 105, and added a
Maxtor LXT-100. Both work fine.

After noticing that internal hard drives cost less than external, and that
there is room for one more drive in the 3000, I have but a few questions
about putting in a new drive:

There are power connectors for two internal floppy drives, but just one for
the hard drive.  What to do?

I didn't notice any termination on the included hard drive.  What would
you need to do to it and a new drive to make the scsi termination scheme
work properly?

Does the front of the case cause problems for any new hard drives?

Is there anything interesting about the cabling required from the existing
(short) hard drive cable to the new device?

Finally, does anyone have any recommendations?  I would be looking for
80 - 105 megs at < 25ms access time.  Give name, price, and dealer.  And
I refuse to buy from Montgomery Grant.  I don't trust them.

Please E-Mail, and I'll post a summary if anyone's interested.
