I have seen posting mentioning 2.5" drives sobstituted for the original
3.5" drives in Mega machines and TTs.  What does it take to do that?

Jim,
        I've never seen the inside of a mega...but I'd assume all you
need is 2.5 to 3.5 bracket...these are pretty standard at PC mail order
and retail places.  Simply call and ask for SCSI 2.5 to 3.5 kit...
They "should know" what you're talking about.  It should include a
mounting bracket and possibly a cable (I'm not sure if 2.5 SCSI uses
the exact cable as 3.5 drives...possibly smaller but same pin-outs?).

Hope this helps...
Brian

Hi folx,
        It is my understanding that most any 2.5" SCSI drive can
work with these machines...you'll need a standard SCSI 2.5 to 3.5
adapter kit which includes a mouting bracket (specify what size bay
to want to put it in...3.5 or 5.25), and proper SCSI conversion cables.
It is a good idea to choose drives that allow the user to ebable or
disable parity...as some Atari SCSI hosts do not like parity.
These kits usually fall in the $20.00 ball park range, and can
be purchased from most any PC mail order or retail outlet.
I have not tried this personaly...but SCSI is SCSI...your biggest
problem may be "if" the smaller drives use a different size cable...
and getting power to the drive since alot of the 2.5" drives run from
termination power rather than having a special cable running to the power
supply.  At any rate...you should be able to get this combo to work...

You can get any IDE or EIDE drive to work in the Falcon...at least
I've not heard of any that don't work yet...there may be limits to
how large a partition can be, depending on which driver software you
use...but they all should work.  It's simple plug and play with
an IDE or EIDE drive...a small ribbon cable that plugs right onto
the Falcon mother board.  If you don't have a mounting bracket, you
can order them from Toad (and other Atari retailers), or make your
own from light gage metal, a drill, and a good pair of metal cutters or
nibble tool.

SCSI drives should be a similar case to the IDE drives.  I've not
tried this...but I believe there is an internal SCSI bus in the Falcon,
I'm almost positive there is one in the C-Lab MK Falcons, and if the
Atari Falcon doesn't have one...I belive Toad has an offer to install
one for you.  Personaly, I suggest you get the 3.5" drives and order
or build a kit that will allow you to put this type of drive in the
Falcon.  The 3.5 drives usually give you a lot more performance and
space for less cash!

IBM used to make them, but demand was very low.

AFAIK, they have discontinued production.

You can get 2.5" IDE drives + an IDE to SCSI adapter (which is small
enough to fit onto the drive).

I have seen them advertised in Computer Shopper...
Not much advantage over a 3.5 drive really...unless you're wanting
to put it into a Note-Book or other small space.
