I'll give that a try, thanks Chris.
The hardware supports multiple drives just fine (one per controller). The power supply
shuts down with three hard drives, though, the surge current is too high. I could work
around that if I ever needed two. Two drives is not a problem, and my RSTS code supports
this.

Hm. I remember that POS 2.0 and above would just format the hard disk and go during the
install. Likewise I don't know if you can have multiple hard disks in P/OS so
that's a pain in the tail.
Boot from floppies and just init the raw disk.

knew, long ago for V2...
