Thanks for the discussion on cable select, I had never seen what the reason for it was beyond, as you described, convenience for the manufacturer.
As I noted above, the two drives on my machine still worked together when in cable select mode, I don't think the original ribbon is IDE2 but is is split, [I thought to facilitate routing...] (how can I tell- if it's a smooth ribbon it's not, if its split with a twist it is ?.. )
I plan to put them back together with the DVD as master & CD as slave. Does it matter which is on the end of the ribbon ? (SCSI can be fussy about that....)
