Oops.. should have mentioned this for clarity:
The original 128K Mac definitely can boot from the external hard disk.
But without a later 512K / 512Ke ROM you must first load MacOS from floppy,
and have the proper extension on your OS disk.
While I agree the process you describe is sound, ISTR the extension
took up so much RAM from a 128K machine that there really wasn't
enough left to open the only apps of the day - MacPaint and MacWrite.
All the code _was_ compatible with the board and the original ROMs,
but there just wasn't enough RAM to make it useful. You could noodle
around the disk but not open any files, practically speaking.
There was an SC20 at the VCFe. It sold very early on the first day.
