It has been a long time since I used the VDP-registers, but it can be
achieved by setting/resetting a bit in one of the VDP-registers (like...
VDP(1)=VDP(1) AND &B11110111... just an example, this won't work, I guess).
Disassemble the BIOS addresses #40 and #44 (I think these were the BIOS
addresses for disabling and enabling the screen), and see which VDP-register
they set and/or reset.
Boy... I sure should maintain my MSX-knowledge... It's remarkable how easy
you forget these things ;)
