FIG Forth was available for the PDP11 at one time, and at least one varient included a small bootstrap which pulled the Forth kernel, etc into memory. Disk access was then via the standard 1K 'screens'. I think the only disk it supported (both for booting and for reading/writing screens) was the RX01 (and maybe later the RX02). It would be possible to modify the disk I/O code to handle other devices, I guess. There was also a version that ran under RT11 and used an RT11 file as a 'virtual disk' to store the screens. This is the only version I've ever seen, and not having an RT11 license I can't run it. If anyone knows the whereabouts of the standalone version I am interested. I am pretty sure it was Public Domain (most FIG Forths are).
