This was the most important request from the marketing dept: make the 72S fully compatible with the 71B

Quote:Note: Some programs (e.g. C71) use the WINDOW command to control output and may leave such settings in place, which can appear to have disabled the wrapping feature when using the 2-line display in Emu72. If this happens, just use the command 'WINDOW 1' to reset its defaults and the wrapping display will be restored.

There are some interesting things you can do with the WINDOW command on the 72S:
- with WINDOW 1,22 you are in true 71B compatibility mode,
- you can also do WINDOW 23 to use only the lower line. This is how I made the illustration picture above (and on my site):
VER$ @ WINDOW 23
- you can also use funny settings such as WINDOW 12,33...
