Bob:

Yes the AN1x will display the ROM version.

You need to put it into Diagnostic mode:

I think below you actually want to press, I think, 1, 2, 3 to go into 
Diagnostics.  Not 7, 8, 9.

Give that a try first.  I don't have an AN in front of me right now.

You definately need the latest EPROM though.  It fixes a lot of things.

AN1X Factory Reset/Test Procedure:

Press  [7] [8] and [9] in the "Program Change" pad and power up.

          Follow the menus to reload the O/S and Voice selections
