I always liked this graphic of the timeline:

The IIc revisions (and the IIe, I suppose, too)  are the only ones you
really need to worry about ROM versions.  The IIc are of course 255,
0, 3, 4, and 5.  I'm not sure what you'd call the IIe ROM revisions...
often they coincided with the case they were in, but upgrades are
always possible.  Hmmm.  You might need to have a classification for
the chassis vs. the ROM or even motherboard... like an early A2S1 that
got upgraded to II+ ROMs, an A2S3 B&H, or an IIe that got a IIgs
retrofit.  This sounds like a fun database modeling project!
