Hello, Kirill!
Somehow I stopped my hangover in the previous message about your proposal
to read the values of ports #EFF7, #7FFD...
I sent the letter, and then thought about it. But it should have been the other way around. :)
Sorry.
Why the hell come up with some new ports if you can read directly from these.
Just set the registers and that’s it. Well, one element at a time, but you can probably do without them
.
All the best.
Roman.
