Thanks, trag, I'll have to check out those parts DigiKey, those PATA cables look just about perfect for moving chunks of signals around inside 'Books & Duos! Have you got any idea about what the MoBo connectors Apple used for IDE and SCSI flex cables are called?

@Mk.558: thanks, the black one looks just about perfect for my 2300c and PB150 hacks. Using one of those should leave plenty of room in the HDD Bay for installing the Asante Micro EN/SC.
