Bank 6 (or 7) doesn't work at all. I don't know what it's doing exactly. It does display the text but it does not scroll it.

Bank 5 (or 25) works - sort of.
I can scroll it left OR right continously without issues but when I change direction whatever is in the non visible part the buffer comes back on to the display shifted down by one row - at least I think that's what happening.

But it's fast, that's for sure.
* Mine was like 7ms or something like that
* tumblweeds was more than twice as fast at 3ms.
* Richards comes in at 0.2ms - amazing.

Mine and tumbleweeds simply scrolls the display, anything that's shifted outside of the buffer is lost while Richards rotates it so they're not exactly the same.
