I remember a year or more ago someone posted a demo using a ZXpand to show a menu of about 20 selection options. When a letter was pressed on the keyboard a screen was loaded in either text or graphics. Another key would swap between text and graphics. This would show about 20 highlights of ZX81, it’s hardware and software.
I can’t seem to find the thread.
