We have had to remove a 40 MB disk out of a IIsi and I would like to
make this disk a second internal drive on an old Mac II. I'll simply
screw this Conner drive into the chassis where the second floppy would
go. I'll also need to set the SCSI ID jumpers on the Conners (Anyone
know off hand what the jumper settings are on these? CP3040A's) and
deal with the terminators.
I'd like to know what I have to do wrt to power and SCSI ribbon cable
though. Can I simply make Y cables or should they be Daisy-chained?
Are there off-the-shelf kits to do this?

Make sure that disk 2 is terminated and disk 1 is not. I think you can use a Y with the power. -- Matthew T.
