Hard drive is terminated correctly (single drive, with jumper on "TE").  It's listing 2,053,935k available, 44,558k used--which comes to 2049.3 MB, so that's interesting... I'm surprised it even let me partition it that size if the OS doesn't support it.  I used a patched version of Apple HD SC Setup to setup the drive as the unpatched version I guess doesn't play nice with non-Apple drives.

Voltages measured at floppy port, pins 5, 6, 7:

-11 V

+4.9 V

+11.5 V

Those are low, but what's considered necessary for reliable operation?
