EI> Please tell me how to work on the Spectrum with a mouse. I mean, ports, etc.
There are only three ports, you read from them and that’s it:
#FBDF - X coordinate (0...255), move to the right - number
increases, reaches 255 and resets to 0
#FBDF - Y coordinate (0...255), move down - number
increases, reaches 255 and resets to 0
#FADF - buttons by bits:
bit0 - left controversial issue, some believe
bit1 - right / vice versa ;-)))
bit2 - average
if the button is pressed - bit=0
Here, I found a certain mouse driver, as an example:

In my opinion, the standard is just the opposite. At least almost everywhere it’s the other way around.

I don’t need fairy tales here! Even in the emulator it’s like this by default!
And in formats there was always a left 0. And some bad people right
The button is used as a left button, which is why all sorts of left buttons appear.

ah, well, here it begins.....
I won’t argue which button is the left one, only in the very first
The descriptions of the mouse mentioned exactly what I wrote!
And just so you know, “at least almost everywhere” they’re already doing it
auto-detection of the active button, since no one
knows the standard
Well that's it *MAS* with a sledgehammer

Here in formats they use the system of the first button pressed: which one was pressed
first, it became the left one by default, IMHO the most convenient thing there is...

Exactly... But it sucks. I remembered - I kept pressing the wrong button.
No one is stopping you from making a “Swap Buttons” switch in the program.
