These are the differences I know of-

ATS 4 (first run)- 4 line 20 character display, power switch on bottom side

ATS 4a (second run)- 3 line 16 character display, power switch on top (even with others)

ATS 4b- 4 line 20 character display, power switch on top (lower than others)

The only other significant difference is the 4A used a different sized power jack then the 4 and 4B. Circuit wise, they are all the same, with the exception of the different wiring for the ascii display used on the 4A, and of course the different firmware to run the display.

Steve,
Is there I way I might add AGC to an A?

Not really, it would be hard to squeeze in the additional circuitry needed.

I have a 3 line / 16 char display and power on the bottom. Is Wayne's list complete?
