Hi Tom,
Yes, that buffer works well for text based programs. There is also the
ALTLCD buffer that can be used (carefully) to save data. Unfortunately
those buffers don't save any graphics content, so that still has to be
read back from RAM in the LCD controller chips directly.

The good news is that there IS a character buffer, so you can read
back text data from the screen.On a 32K T102, the buffer starts at
65024. It's likely going to be different on other machines and memory
configurations, though.
