I changed the disk drives and VGshki, it was all in the ROM!
by the way, doesn’t anyone need to increase the Leningrad speed to the Pentagon speed?
And maybe someone has a program with which it would be possible to
adjust the disk drive???

oh, I suffered so much with Leningrad until I increased its speed!
by the way, I managed to increase its speed right up to 74 thousand !!!
though in a completely left-handed way ;)
but I’ll tell you exactly how to increase it to the Pentagon’s 2VP: ;-)))
that it’s a gate one, that’s for sure!
if I haven’t already forgotten its speed is about 69 and 66 thousand
in general, what I did was by pure chance:
I cut the WAIT of the processor, I run the test - and there are 8-))))) 69 and 69 thousand,
just me I forgot to apply +5V to the percent through a resistor, otherwise the speed
had a terrible effect ;)
this is how to do it without white wires, although what is strange is
that we managed to do this on 2 machines out of 3!!!
now how to make the Pentagon speed:
there is such a m/s D5, to which /BK comes to the 9th leg,
we cut this /BK and let it go ground on the 9th leg! 8)))
though there are only problems with the int, oh how I fought with it, I managed to burn a bunch of microcircuits, but I settled on the switch between the Pentagon and
standard int! if you look inRamDoctor to match the int,
then on the right curb it will match, but on the left it will rattle :(
because of this, the multicolor on the left side is not multicolor at all (for example
PART MULTICOLOR in INSULT)!
if anyone knows how to deal with this, please write to me!
well, if anyone wants to know how to increase the speed to 72 or 74 thousand,
write, I’ll tell you - you just need to short-circuit something ;)
but I don’t remember what, and I also discovered this purely by accident ;)

have you tried it???
I ran everything - everything works fine, and this very test, I tested it as best I could
and everything worked!
although on one of the 3 machines this did not work :( it stopped logging into TR-DOS

okay, I came up with it myself ;)
in general, I had a glitch like this - some time after turning on
the image began to rattle, well, I understand - the m/c is overheating, let me think I'll wipe it with alcohol and cool some microcircuits, I found it - it looks like it turned out to be 555IE7, in general it will be in the upper
left corner if the RAM is in the lower left (I'll definitely look at the diagram at home and
I'll tell you its number, in general, in the absence of the 555 series, I had to put 155
I look - everything is OK, the image is not It's rattling, only it's moved _a little_,
well, let me think I'll run the test again (my RU5 was glitchy at the time)
generally I'm running RamDoctor 2.0 with RAM, everything is ok, and the speed rose as much as
72 thousand, but unfortunately, as it turned out later, the INT has moved out :(
well, in general, my eyes popped out of my head 8-)))
then, as there was nothing to do, or rather, once againto fight against INT, I started shortening all sorts of suspicious, and in the end
not suspicious places at all ;) I shorted like 13 and 12 leg in IE7 - I see the image is still moving, I think it’s interesting, I’m loading the test again - and the speed is 74, almost 75 thousand !!!, only the INT has moved even
more :(((, but but nothing has ever slowed down!
I can also tell you how I checked the RAM for lousiness ;)

On two machines that I tested, it did not work, when loading from

Imho, if the pulse is still active, and the interrupt has already been processed, it will go a second time.

At the bottom there should also be a multicalor, but a little behind the curb. By the way,
depends on the rewrite of the record in the second counter. There, at the preliminary installation
the number is changed.

RTshki - bad, imho it’s better to do without them. They cause a lot of problems.

VY> People, explain what the length of the interrupt pulse influences.
on interruptions, if it is long, then you can run into double
operation, when nmi2 works, they do ei, then it
will work again. Which is bad.
btw, on KAY256 a digital exposure was made. Those. after 3
machine clock cycles, after confirming the interruption, it turns off.
:)
Good Luck...

If it’s not difficult, then give it to me (maybe I can attach it to Leningrad1).

Yes, probably no one has read it, since only KAY thought of it before???

The KR580VM80A and others like it had such an INTA signal, in the RK86 they put the sound on it and wrote the commands #F3, #FB. In the Z80, due to the lack of legs
to confirm the interruption, /IORQ and /M1
are generated at the same time, it remains to remove /INT.
The only problem is when interruptions are prohibited and turbo - then
you will have to use air conditioning.
Nicolaus.

...why were you telling Alex Letaev about something else! Re: Cry for help

NM> The KP580VM80A and others like it had such an INTA signal, does the PK86 have a similar sound?! Nothing like that! INTA which was simply an external
signal prohibiting interruptions. There is no analogy with interruptions
inta on the ZX. Although it could also work as a confirmation of interruption
(i.e., upon arrival of inta, it prohibits interruption by transitioning to
the active state)...

There are no air conditioners, but there is a turbo.

Hi, Max,
In a message dated 20 Dec 97 you wrote to Nicolaus Mezencef :

What does prohibiting mean? Interrupts are disabled by software, as is
known...
MR> there is no inta on the ZX. Although it could also work as an interrupt confirmation
That’s exactly how it works. If interrupts are not disabled, and the processor
receives the /INT signal, it begins processing the interrupt, generating
the /INTA signal, and letting the hardware know that it has received /INT. Which in turn is convenient to use to remove the same /INT. In the dock, read
the description of this signal, and understand the meaning of the letter “A” at the end...

DG> What does prohibiting mean? Interrupts are disabled by software, as

by software/hardware. In the Z80, as in an advanced process, the masking
of the interruption is done on the crystal, while on the 580 it is necessary
to install external logic.

InterruptAknowledge IMHO. However, it also serves to
prohibit/enable interrupts.

damn... exactly! It was necessary to confuse these two signals. I

It’s also simply done on Scorpio Turbo+. For the duration of the signal INT=~9mks, the turbo mode is turned off. That is, the clock becomes 3.5 and therefore there are no
problems.

Well, if you immediately develop the circuit taking this into account, it’s easier.
When I turbocharged my miracle (by the way, exactly 2 times), then it seemed easier to me
to add an extra TM2 to the already existing air conditioner.
The main thing is that it worked perfectly. ;)

Who has a leg that prohibits interruptions? The 580 has it. the z80 has a trigger on the crystal. The maximum is an interrupt reset system upon confirmation.
that's all.
