How to connect an old SCSI (MacSE) drive to a Powerbook?

[gregoireg]

I have a working PowerBook 145B.

I have an old SCSI drive taken from a MacSE. It has a 50-pin map cable and a 4-pin power cable.

I would like to connect that drive to my PowerBook 145B.

I'm aware of the PowerBook HDI-30 SCSI connector and cable such as https://www.cablesdirect.com/store/p/2884.aspx

What kind of adapter will I need? Especially, I'm confused how I'm going to power the SCSI drive.

Hi @gregoireg!

When situated internally, SCSI hard drives generally have a 50-pin connector to connect one end of the ribbon to another. You can place the hard drive in a SCSI box and then connect to your PB 145B with the HDI-30 cable. Alternatively, you can hook up the HDI-30 cable to a 50-pin to db25 SCSI-1 adapter that looks something like this:

as for power, you can get something like a modern sata to usb converter. and then JUST use the power adapter to power the drive.
sata to usb

the power supply and molax will be seperate. so you could just use that along with what retr01 suggested for the scsi part.

another option would be just to get a atx power supply and just use it to power the drive.

good luck!

Another option is to take an external hard drive or CD-ROM case, then install the drive in that. Use a normal HDI-30 to DB-25 SCSI adapter and a DB-25 to 50-pin Centronics cable with terminator to connect the drive to the PB.
