Some more progress-- it's now booting up to the question-mark disk screen, with the mouse cursor in the corner of the screen.

:O That's astounding. Congratulations!

A little tidbit of information that may be of interest to you: the Mac Classic (essentially a re-release of the Plus) came with a bootable copy of System 6 in ROM.

the Classic / had sufficient space on the machine's ROM to fit a stripped down — though fully functional, including AppleTalk for networking and the MacsBug debugger — version of System 6.0.3 with Finder 6.1x. Users simply had to hold down Command-Option-X-O (⌘⌥XO) at startup to get it to boot from ROM.
