I deleted dblstsc, multiscan and dblpal from /devs/monitors
Rebooted and all is well. THANK GOD!
I'm so proud of myself for fixing the problem. I have been tearing my hair out for 4 hours trying to figure this out...
So now I am looking at 256 color desktop. The resolution sucks, but I think a scandoubler is what I'll work on next...

You should not have deleted those monitor drivers, just move any you're not using to Devs/Storage/Monitors for safe keeping.
With you're setup you could try 640x480 using the MultiSync driver + the VGA Only monitor driver (they should both be in Devs/Storage/Monitors).
Basic idea:
1) copy them both from the storage draw to your Devs/Monitors draw
2) Restart
3) Got to your screenmodes prefs and select the Multisync 640x480 mode and then press 'test'.
If you can see the test image then all is well, otherwise your monitor doesn't support it.
I used to use VGA 640x480 in 256 colours before moving to HighGFX 1024x768 (you'll need that IndivisionAGA) for this kind of thing
