I highly doubt it will be backwards compatible, but i think it shouldn't be too hard to port old programs over to the new calc (with the exception possibly of TI-Boy, which who knows what crazy hacks calc84 used). Also, the lack of an I/O port means that Steins;Gate won't have sound. I'm also really excited about the ez80 (and have been reading through the ez80 manual the past couple days). I'm also a little worried about the screen, but either way we'll still be much better off than with the CSE. I think this is the calc the CSE should've been. I'm also really looking forward to it and will definitely pick one up as soon as it gets released (and one's listed on Taobao).

I wouldn't be too surprised if, for the normal TIOS, the CPU would be in z80 mode all the time, hehe

In order to access the extra memory it needs to use ADS memory mode. There is also a mixed mode. I am not sure if this allows for bankswitching though.
If you like my work: why not give me an internet?

Having to add some wait cycles isn't that terrible of a thing. You could even be smart about it and do some important things in these cycles.
I'd also expect that you'd be able to poll a port on the LCD to see if it's ready, that way you can get things queued up while waiting for it to be ready.

According to the doc you like suffix ld and other commands and that will make it mixed automatically.
