LE AND GRAD-3

ZXNet echo conference «zx.spectrum»

From Max Romanoff To All 23 November 1997


Alex is that you?
...why were you telling Sergey Mukhachev about Re: LE AND GRAD-3?

AL> The St. Petersburg plant produced computers under the name "Kompazit", there was a diagram
^^^^^
in this case, I'm also a plant :)))

AL> and a board very similar to Leningrad 1, but with improved synchronization
AL> on TM2 and with two IP16s instead of IP9, and there was no need to set a delay.
AL> This is probably it.

No, it's not him. Composite turned into KAY. (Kompasite-AY.), and the
composite itself is a mutation of the Zonov board.

Good Luck...


... There cannot be a crisis today; my schedule is already full.

And what then is Leningrad 3???

With respect, Alex from FFC COMPUTERS.

AL> :-))))))))))))))

btw, I was wrong, not COMPOSITE, but COMPOSITE. ;) Now they are doing
advertising. Signs, I mean.

It seems like they said that the bead is big.

Good Luck...

From Serge Zonov To All 26 November 1997

My second board was called Composite - developed in the summer of 1988, the templates
and circuit were sold to the Composite cooperative (hence the name) for twenty :-)
blank printed circuit boards. Since the board corrected almost all
of the shortcomings of the first scheme, it received maximum distribution, although
it was called by many the same as the first. Outwardly, it was not so
easy to distinguish them.

MR> Good Luck...
Serge !

Nobody argues. We just didn’t touch on this backstory.

Good Luck...

MR> It seems they said that there is a big one on the bead.

That means there are a lot of them on the bead. Since the one I saw was not Leningrad.
There is also “Master” on the bead.

But the synchronization on it is better. I have one like this. Thanks for the great diagram.
