To the best of my knowledge, this doesn't work. :-(
A) OS3.5/3.9 are not bootable direct from CD (the Emergency Disk is needed to kick in the system).
B) 6Mb FAST is required.
Even with an SX-1 I couldn't get anything beyond 3.1 going. An SX-32, on the other hand, would make a nice luggable machine for old and semi-modern stuff.
