Everything related to BASIC version 1.x (Oric 1 and Atmos) or HYPERBASIC (Telestrat).
Don't hesitate to give your small program samples, technical insights, or questions...
In $26A is a byte with some control bits:
- Bit 0 -> Cursor status (does the cursor blink)
- Bit 1 -> Video status (does printing to the screen works)
- Bit 3 -> Keyboard sound status (will it do clickety clicks)
- Bit 5 -> Are the two first columns of the screen writable by print
So I guess something like POKE#26A,PEEK(#26A) AND 254 should work.
