This is a PowerBook special and is not a PATA/IDE connector at all. It’s a SCSI connector! Apparently a very custom SCSI connector that isn’t really supported elsewhere, though it appears to be electrically (if not mechanically) compatible with standard SCSI-2 so an adapter is possible.

There’s some discussion over at https://68kmla.org/forums/index.php?/topic/31589-40p-scsi-to-50p-scsi/
There are also devices available that emulate such a drive (using a SD card as backing storage). Note the pinout in the photo matches your drive.
According to EveryMac the laptop you mentioned uses a SCSI connector for its internal drive connections.
Standard Hard Drive: 80 MB, 120 MB* Int. HD Interface: SCSI
Details: *By default, this model is equipped with an 80 MB or 120 MB internal SCSI hard drive.
The 8 pins to the left of your image will probably be used to indicate the SCSI ID of the drive, normally using jumpers. The original version of SCSI could daisy-chain up to 8 devices.
It’s SCSI. The 8 pins on the left are for power. There are no jumper pins; SCSI auto-negotiates. You can get devices like EX Connect to hook it up to a machine.
