Re: Try this one weird POKE on your ZX Spectrum, TS2068 or ZX Vega

Yes does not the issue occur when the system returns to input mode and thus 
has not enough lines to do that. I've seen pokes to this location in loaders 
to stop people breaking in, it just falls over.

There are allso pokes that can make the screen look like itssaving or 
loading all the time, but its been a long while since I did it and I've 
forgotten them.

We used to put  a two line program in and run it, the first simply said 
Elite is loading, please wait, and then the poke and a line that went to 
itself.
