1200 IDE ?
Mark,
A 3.5" drive can be used inside an A1200, but there are several catches
that might make you think twice about trying:
Once you shoehorn it in, the whole she-bang is awfully tight. getting
the case closed again is not for the weak hearted.
You'll need a bigger power supply. Even if you don't have any
expansion on the machine, you'll need a bigger ps. The 5V section should be
able to shoulder the load, but the 12V section doesn't cut it. A typical drive
would probably need a full amp peak at 12V, while the A600 supply shipped with
many A1200s is only rated at .5A @ 12V.
There are no data cables supplied commercially (that I know of) that go
from the small form-factor connector on the motherboard to the 3.5" connector
(or realistically, the connector on the 3.5" drive – not the full width of the
drive).
There are several hack files available for creating a custom data cable
for the drive, but it is not a job for the electronically inexperienced.
It can be done, but it is a hassle.
