I have a 712/60 with 128MB of RAM running NS on ZuluSCSI and it works PERFECTLY. It's really a dream. I use it almost everyday when I want a distraction-free work environment. The configuration advice from Sophie's pizzabox.computer blog works perfectly (block sizes, etc) and all parameters translate fine from SCSI2SD.

The images for nextstep I got from the internet archive and they work fine. I even got DoomED running! In the ZuluSCSI:
1. Configure block size for the HD image correctly.
2. Create a 2GB blank file and move to ZuluSCSI.
3. Copy the ISOs from the internet archive into the ZuluSCSI and edit the config file to point to them. When you eject the CD in nextstep, it will cycle through the CDs automatically - it's super convenient. This way, you don't need to be opening your machine all the time.
Make the HD SCSI ID 6.

To install, do a "sea" in the firmware prompt and choose to install the CD. After installation, normal boot works, but I find it too slow, so I always push Esc and do a "bo scsi.6.0".

I have the original 1GB micropolis hard drive with a clean 10.20 install, but I don't have the installation media. If you can't find 10.20 anywhere, I can try to image it for you. I have the images for 11.11 and they should work (albeit slowly). I think the ZuluSCSI has an eject button and you will need, because I think 11.11 has multiple disks.
