it seems quite happy with the two ultra-2 drives on a 68pin cable on chan 0.

the second channel is also a 68pin.  i want to put on two old cd-rom
drives.  so i got a nicely terminated cable [0], and put on two 68m-to-80f
adapters, see <http://www.scsi-cables.com/images/50large.gif>.

when booting, the system takes a loooooong time to scan the second scsi
channel, and does not see the drives.

i am probably doing something very naive/stoopid.  clues solicited.
