From Dmitry Pugachev → To All 12 January 2002
It was a long time ago, I don’t even remember what year it was.
I developed a circuit so that two screens (7 and 5) would overlap each other without blinking and
int.
I hung #EFF7 on the port.
Well, I’m interested, now someone writes under this device with what? Coder, artist, hardware engineer. (SchemeMan) 2:5026/51.12 AKA 2:5026/63.3

What the hell! Izhnews #0C & PoS-WT demo & Mad Mixels MegaDemo from ASCii
DemoParty hold this feature.
I am probably the only one and the very first to write support for this device.
DP> PS. If you need to explain anything about the device, write letters.
Looking at the diagrams of the Pentagon we see something like this.
an interruption came, draw one line of one screen, draw the next line of the second
screen.
the next interruption came, everything is the same, only the lines have changed, i.e. draw
lines of the second screen, then the first.
If I understand correctly, it would be cooler to mix completely, but for this you need
the circuits to be fixed.
With respect, HIMIK'S ZxZ/PoS-WT.

you can simplify the circuit (at the same time you won’t need to write a manual detection in each
prog): throw out KP11 and the frame rate divider. Instead of the 25hz signal, apply
the SCR signal. Those. It will flicker only when switching screens programmatically.

If you fix it, then there will be more cases and the complexity of assembly will increase.
And I first of all came up with a scheme so that it would be simpler and everyone or almost
everyone could assemble it. And where is complete mixing, because the flickering is already
not noticeable or almost not noticeable.
