Hmm, this is interesting.  I was at Apple today in their Compatibility Lab
and tried this with the Classic there: yeah!  But it came up with System
6.0.2, "Finder 6.1x" and the rest of bare minimum Appleshare configuration.

But, the NIFTY part was that I could make it the startup drive!  Yes!
Thereafter it booted from ROM when turned on, not just with the key-combo.

If this sticks it'll be a cool, undocumented, unsupported feature of the
Classic, very useful to 1M/1 floppy setups.  That is, if that system works
well, which is obviously the question since Apple seems to have decided that
it's not supportable (can't blame them myself).

Note: the ROM disk icon is a floppy icon with a chip on top of it.
