APS battery powered SCSI

[waynestewart]

I have this APS SCSI drive that's battery powered but no external power supply to charge it with. I would have thought it would take a DC adapter but on opening the case on the circuit board where the external power supply connects says AC but no voltage. Inside is 7.2 volt NiCad battery and a 2.5" SCSI drive. The FCC ID is IDKAPS-9000. I've looked on the net without finding anything. I'm hoping someone might have one and could give me some info on the external power supply

I decided to proceed by taking out the battery and using the same voltage of wall wart to power it. It spun up right away so I shut it down and looked for the handiest Mac to connect it to. That happened to be a 6500. I hooked everything up and turned on the drive and it went sprt sprt sprt and didn't spin up. Disconnected it from the 6500 and turned it on and it spun up. Tried it with just a regular 50 to 25 SCSI cable and the same spt spt spt. Tried a different cable and the same.

So I went digging for an old powerbook and a HDI-30 SCSI cable. The topmost one was a 520c. Connected everything up, drive spun up and once the 520c booted, I could read and write to the external drive.

A pleasant surprise. Charged the battery and used it a bit on battery power. Usually after the battery sits dead for a few years it won't take a charge. This unit's likely been sitting in storage for more than 10 years.
