I have to ask because I was trying to put a new drive in my 720 using one of those 80-to-50-pin adapters. The drive is about 36GB, and I did previously have it working in my Atari Mega STe using the same adapter (although it was hard to find a driver that would work with it), but it won't work with my 720. Here's what happens: If I match the address that the old drive was installed at, the machine won't detect any SCSI drives attached. This address would have been first in the boot order (can't remember whether that was 6 or 7 right now as I've already taken the drive back out). If I set the address to one late in the boot order (close to 1 or 0 if I remember correctly), the floppy and CD drives will be detected, but the hard drive still won't be. However if I boot up an HP-UX installation CD, the installation CD seems to see the drive just fine, and appears to format and install to it. However, after installation, the BIOS still doesn't seem to be able to recognize the drive or boot from it.
I'd try to look for a bigger 50-pin drive to put in it, but honestly, they don't get much bigger than the original drive before they move on to the 68-pin connectors. So essentially what I need to figure out is, how new/large can I get with a SCSI hard drive and an adapter before it won't work with this machine?
ALTERNATIVELY, since I do have a SCSI floppy drive in this machine, does anyone know if I'd be able to set up a boot disk fairly easily with HP-UX that could try to hand things off to the OS on the hard drive after it's started to load?
