I did recently get my 4404 running, at last.  It runs nicely off of a
SCSI2SD, replacing the SCSI->MFM bridge, should you so choose.  I can share
the disk image I did of a clean install of the OS, languages, and tools
that are available on Bitsavers.

I also have an MFM emulator image of a disk that I believe went to a 4406,
but I cannot confirm that it's bootable.
