Updated memory graphic

Its a shame they can’t provide a service to upgrade the memory. I’d gladly pay for the part, labor and shipping. You’d think the bigger memory would support a larger local music library index also.

I would think the cost of such a service would outstrip the cost of a new speaker, due to the (perceived) manual labor involved. And, for all I know, the memory and COU might be soldered in, rather than socketed, increasing the complexity of replacement, and the circuit board and power supply might not be sufficient. 

Upgrading the memory is likely to need a new logic board, not going to be cost effective. The labor in trying to re-work the original board is probably worse.

The new board could also upgrade the CPU and radio but I just can’t see an economic case.

if anyone can tell me how to turn a 0/1 value in Excel into a nice icon in a graph, I can update the chart with more info like Voice and Airplay, but it looks ugly as 0 and 1s right now. My Excel skills were pushed to the max to create this chart!

There are two Sub's??? How can you tell which one you have?

By the first four digits of the serial number (YYMM) or by the internal Zone Player Info screen’s model info.

I don’t have what the differences are but that is what you are looking for.

My point is that there are two Sub's version on the diagram.  How do I know which one I have?

Shouldn’t really matter, the storage is what limits what can be loaded into memory, and the storage is the same for both.  In truth it matters even less for the Sub, which doesn’t have much smarts, it simply plays the one channel it’s given.  No playlists, no music index, no account info, etc., so the Sub should be good for decades.  

This new chart has two subs, one with 64/64 and one with 64/128

Yup, there’s an A100 and an A100.2 - I was surprised by this discovery too.
