Note that while in theory the AVO was an added option, the VT102 did not 
have it (or the printer port) as separate parts that were added to a 
basic VT100. The VT102 had a different board with all those options 
already on the motherboard, and no additional options could be installed.

So, you cannot take the AVO options out of a VT102 and add it to a VT100 
(for example).

Also, for example, the keyboard on a VT100 differs from a VT102.
You could use a VT100 keyboard on a VT102, and vice versa, but the LEDs 
on the keyboard of a VT102 are used for different things than on a VT100.
