Would be awesome if it did provide a RTC (and perhaps SDX).

I'm interested. Would this work for a stock 600XL, or is the 64k mod still needed?

While looking at the bank switch table I'd say it's safe to assume that is requires 64KB base memory.

Any RAM on the MB isn't needed, because will always off.

Is that plug n play? And what software would make use of it?

 

The only software needed is for configuration change and for FLASH programming. It will be provided.

No. It doesn't require any RAM at all.

 

Does it fin in a 400?

 

Unfortunately, don't.

 

Is it flashable via software or do we need an EPROM programmer?

 

It is flashable.

Beautiful device. Hopefully, that will get more programmers writing 816 compatible software. :)

I was just thinking about upgrading the RAM in my 800XL so I can play some >64K games so this would be awesome.
