Monitor for Spectrum
ZXNet echo conference «hardware.zx»
Hello, Ovvnex
Ovv> monitor "Kodis"
!!! give me two of these monitors please!!!
This is a spec flowering monitor!
megarules!
I saw such a set - ATM turbo + Kodis and the person in the store was copying the disks
and sold
and Monique was wearing a protective screen and a Honey Commander
real oldschool monitor!
Hello Orionsoft
Ori> !!! give me two of these monitors please!!!
Ori> This is a spec flowering monitor!
Ori> megarulez !
Why is he so good? Is it easy to get along with Spec?
It’s just that I haven’t even heard of this brand. And anyway, could someone make up a thread?
"table of ranks" of displays according to the greatest "suitability" (write about compatibility
I can’t, because “...Spectrum was designed specifically for TV.” (C) Nemo) for
Spectrum. Well, or each of the real people, if there is free time for that,
I would answer in this thread which device displays the picture of his Speck, huh?
In my opinion, IMHO, for those who are thinking about real life, such a topic would be useful.
Hello, Ovvnex
Ovv> Z.Y. By the way, there is an opportunity to purchase a Kodis monitor - tell me
Ovv> what kind of animal is it and how does it fit the Spectrum???
This monitor is a Soviet EGA monitor. About 8 years ago I used it
together with my ZX-777, until I ruined it with my research in the field
electronics - I had to sell the picture tube as it was no longer needed. Generally good
monitor, but that’s where you need to send the signals correctly. I'm even on cardboard
I collected the scarf so that the signals would be correct. There was a passport from him somewhere, if
I need a scan and the firmware from RT5 was there.
Hello Mick
to Ovvnex
I use with spec without problems Monica:
MC6121 - domestic cga
saha computers - ega
aztech-ega
everyone is working together

Hello Orionsoft
Gee, this guy (MC 6105) has a mirror pinout according to the Soviet system: D!
So you need to be careful when using bourgeois connectors with
correct pinout ;)
ZY There should be complete circuit diagrams for MS 6105 on the net.

Is it possible to bring a diagram (on cardboard) to the studio??? It's very necessary!
Hello, Ovvnex
Forgot to add! Monica "Codis-M" has a color module MC 4-6 s installed
PAL/SECAM decoder and there is a composite video input. As I understand it, speck is possible
connect directly to the RGB color module. Tell me the circuit design
solution please! (because I don’t have a diagram of the module and couldn’t find it on the net).
Hello Mick
Mic> It is worth applying co signals to the corresponding RGB inputs of the color module
Mic> Spectrum, and clock pulses to the video input of the same module.
That’s the thing, I don’t know where these corresponding RGB inputs are. Schemes
I don’t have a color module, and I imagine the circuitry of this device very
vague :v2_conf2; !; Maybe there is someone in the conference who connected the Speckie to the TV
with such a module or having its circuit. I will be very grateful!
Hello, Ovvnex
Ovv> Monique is exactly "Kodis-M". And, alas, it even looks different from the monitor
Ovv> shown in the user manual sent by you (on the front
Ovv> panels have only 2 controls - brightness and contrast). Regarding
Ovv> color module with pal/secam decoder, so this one is late
Ovv> independent modification by the owner (color module from some
Ovv> 3USTST (4USTST?) TV, there’s even an input selector button
Ovv> (composite/9-pin). I thought that since there is a module
Ovv> color MTs-4-9 (the inscription on it!) is worth it, then connect the spec to it
Ovv> is possible, as with old TVs. The trouble is that the circuits of this module
I couldn’t find Ovv> anywhere, and I’m not good at circuit design. Help!!! :v2_smile;
Well; since there is a color module there, then you probably don’t need anything yourself
invent. It is worth applying signals to the corresponding RGB inputs of the color module
from the Spectrum, and the clock pulses to the video input of the same module.
Hello, Ovvnex
And describe what this “color module” is (dimensions of the board, what
submodules are plugged into it and what kind of devices are installed on it and on the submodules). Maybe
be it similar to something everyone knows?
If you have a digital camera, you can even take a photo.
Hello Ronin
Well, about the color module - I don't know, I saw a code-m connected to a regular cga-pc
and also to spec for rgb, but not for composite.
at least if there is a composite input, it is easy to find by feeding it
Video and getting a b/w picture :)
Hello, Ball Bess
Well, there should actually be an “rgb input” connector, it’s something like a digital monitor.
but it seems with analog rgb inputs (I could be wrong, or maybe different
there are modifications). the order could be like this:
- you find land :)
- take one of the rgb and poke until you find a floating picture. now we'll have her
sync.
- take the SSI (or composite) (positive polarity seems to be needed there) and poke
until you stop the picture line by line (if you haven’t stopped it, take SSI
negative polarity and look again)
- take the KSI (positive polarity seems to be needed there) and poke for now
stop the picture frame by frame (if you haven’t stopped it, take the ISI negative
polarity and look again). you may have to twist (and find first)
frame rate adjuster if it is set to 60Hz.
- now you take RGB and poke until you find which color is where (it’s convenient to do
border (paper) 1,2,4 - and look for the corresponding color)
- drink beer, eat meat. :)

Yes, I have a vague assumption that the person who had it originally
I modified the monitor myself and did not warn - and now the person is suffering :( .
So here is a diagram from a radio magazine - a 4USCT color module. Briefly for starters
Find the video input and just feed the video signal from the Spectrum. As you can see b/w
the image is the first step to victory.

Hello, BaguM
Bag> I see, thanks.... that means I’ll have to come up with a line frequency and

Finding EGA is not a problem, just get on the phone and call the nearest research institutes or
institutes... Turbo2+ works great with EGA!
Hello, CHRV
They kind of threw everything away (in the sense that in troubled times, the employees kicked it out).
There is nothing living in the city - almost everyone has rented out most of the area
businessmen, and in institutes.... it’s generally cool there - from my specialized
the majority use drawing boards and in some they practice PENCIL-GOUACHE
rendering of future buildings...
Of those available, only vga and higher from merchants, or rolled oats from a friend...
Hello, BaguM
2ALL
Please tell me what kind of monitor this Visa MC 5420 is?
Information is practically not found on the Internet (maybe there are similar models,
should you search for them?). Also a question about contacts (pinout) what and for what
answers. There are 7 contacts going from Scorp to the monitor, they are colored (apparently for
digestibility:) 3 brown, 2 green, black and blue. These wires are on
Scorpios are soldered to various microcircuits and creating a similar design on
the second (possibly similar) Scorpio does not give visible results (not
shows). :(
I wanted to organize a single connector for two Scorps.
File: visa_mc5420.jpg http://zx.pk.ru/attachment.php?attachmentid=3912
Hello Vovoi
Judging by the number of wires and the method of soldering them to the speck, the monitor is digital
EGA, wires according to H-Sync V-Sync R G B Y GND (pinout must be looked at
the corresponding connector must be standard).
I can’t say anything valuable about Scorpios.
Hello Sonic
Son> An alternative is monitors from video surveillance systems, also in color
Son> yes, I think the cost is about the same.
Son>
A color video surveillance monitor costs about $250, and even a CRT. Better
really look towards cheap LCD TVs, but they, I guess, except
There is no composite input anymore. But I want to connect both RGB and S-Video.
Hello fan
Gentlemen, what exactly is the problem?
The market is full of Chinese LCD TVs costing ~4000 rubles. I think
this is better than an EGA killed to smithereens, from which after a while the eyes turn to
Your forehead will pop from such super quality...
An alternative is monitors from video surveillance systems, there are also color ones, I think
that the cost is about the same.
VGA, VGA... This is just a stereotype imposed by the fact that other monitors have
we simply don't exist anymore. And what exactly didn’t suit us at the time?
TV? As far as I remember the quality of the picture. Gentlemen, this is the 21st century, this
the problem has been solved a long time ago. Even a resolution of 640x480 is such a TV IMHO without
there will be problems. And without nasty flickering because it’s LCD.
Hello, tnt23
tnt> It’s really better to look towards cheap LCD TVs, but

Since there is a composite, then there is also RGB. You just need to take him outside. There are no miracles
it happens however.
Hello Sonic

Son> However, miracles do not happen.
I would like to hear an answer from a specialist.
How realistic is it to get into the circuitry of such a TV and get it right?
connect for example Scorp, this is also a TV, albeit an LCD?

I specially bought this TV Vitek VT-5005, fortunately the price dropped to 2500 rubles.
Opened it :)
The display uses a 5" TFT panel PA050XS1 from PVI (Prime View
International Co.)
Panel resolution 320RGB*234.
The panel is designed to work in NTSC and PAL standards.
The RGB inputs of the panel itself are analog, but a bunch more are required for synchronization
signals :)
The panel is connected to the TV board using a 30-pin flat cable.
I haven't found any RGB inputs on the TV board yet :)
If anyone is interested in the PDF for the panel, they can easily find it on the Internet at the above
the specified brand.

is it already a regular VGA CRT or TFT on which the PC hangs?
Hello Sonic
Son> Why, DVI monitors aren’t in fashion yet?
Son> Although among us, old schoolers...
Why not in fashion? Still in fashion. I don’t know about you, but here they are more expensive
regular TFT, although prices are steadily falling and in theory this is not an obstacle.
The problem is that many already have a monitor, it’s good if it’s CRT, then at least
the upgrade will be beneficial, and those who already have TFT will not change it.
Hello Sonic
Son> as for frequencies - is such a concept applicable there? ...
Son> a big shift register that displays its own state.
Son> Doesn't matter how fast you load it
It’s just that it displays its state dynamically, or do you think that from
control circuits for each of the many millions of LEDs go separately
wiring for static display independent of speed?:smile; So;
As for frequencies, it’s very applicable.
Hello icebear

Moreover, modern TFTs are dual-purpose (VGA/TV), and even if
they only have a VGA interface, then their frame rate is from 47Hz, and why not
screw it to this VGA Spec? You double the reading of lines - and forward, even none
no additional converters needed: smile; .;

No need for extra. TV->VGA converter, because VGA is the standard mode of the video controller. But this
VGA with frame rate 50Hz. Accordingly, for old TFTs that cannot work at 50Hz
- doesn't fit. Almost all new TFTs with a 16:10 screen are capable of 50Hz frame rate. U

Hello, tnt23
tnt> Can I have a photo of the TV board? or at least the most noticeable chips? :)
There is no point in taking a photo, since everything is already clear.
The LCD is controlled by an IR3Y26A chip from SHARP.
The DataSheet search for this chip has not yet been successful (maybe someone
will be luckier).
I downloaded DS on IR3Y29AM, functionally the same and even the body is the same (48
leg TQFP).
But viewing the oscillograms showed that the pinout of the chips does not match.
Judging by the structure of IR3Y29AM, it is quite possible to supply RGB signals to the chip,
but the board does not provide such a connection.

Hello hero
her> if you think this method is real
What is there to count? God be with him, with 1024x768, let it be 640x480x100, or again
there are some prejudices :). Yes, and there’s nothing special to consider - they were somewhere on the forum
links to Western ZX creativity with photographs of OSD images on the monitor,
so there are 640x480x100HZ.
Hello, Black_Cat
The device was abandoned as a failed experiment, of which 5 monitors had
tested current 2 monitors (and ancient ones, in the last year of their life)
understood what they wanted from them. So you can safely forget about him, continued
experimentation, it may be possible (possibly still in this century) with the implementation
75Hz mode and displaying average color dots over 3 frames (something like that
it's called).
Hello, Black_Cat
Take a calculator in your left hand and in your right hand..... but nothing in your right
no need to multiply 1024*768*100 and see what number you get, and then
think about it. If the number seems small, then add another 15-20%. If everything
is equally small, then take into account the number of monitors for which 100Hz is acceptable
frequency
Hello, Black_Cat
And I saw OSD on the monitor at 50Hz. So this is not an indicator
Hello, Black_Cat
Well, I don’t have such a monitor :) But if you think this method is real, then
nothing stops you from learning VHDL, Verilog, AHDL and writing in a couple of hours
schematic If we can help with the language, but with the idea we’ll lie.
Hello icebear
ice> Can I ask about the shape of the pixels at these 256x768? And also about
ice> name of the figure displayed on such a screen, which in normal

A circle with pixels magnified 4 times in both coordinates.
And regarding how many Hz the TFT shows in real life - what difference does it make, as long as
He synchronized with the one they gave him.
her> And I saw OSD on the monitor at 50Hz. So this is not an indicator
This means that the OSD showed that the monitor was operating at 100Hz?
Hello hero
her> If the number seems small, then add another 15-20%. If everything
her> is not enough, then take into account the number of monitors for which 100Hz
her> permissible frequency
The number is not small, but it is not relevant, because... the real string will be 256
pixels (you really have to sacrifice the border, but with the border let them look at
640x480). Those. in reality it will be 256x768x100 - a very real number: smile; .; A
for TFT, which we were actually talking about - 100Hz couldn’t be more familiar.
Hello hero
her> 75Hz and displaying average color dots over 3 frames
Why not 100Hz?? And you don’t need to average anything, you just quadruple it by row and
that's it :smile; At the same time; and 1024x768 can be easily implemented :smile;
A; They are getting rid of everything old, including TFT, everywhere in the world. It's easier to buy a new one
why bother with old stuff :smile:
Hello, Black_Cat
Bla> That is. in reality it will be 256x768x100 - a very real number: smile;
It is possible; ask about the shape of the pixels at these 256x768? And also about the name of the figure
displayed on a screen that in normal resolutions is a circle.
Bla> And for TFT, which we were talking about, 100Hz is nowhere nearer.
Well, well. http://www.experts-exchange.com/Hardware/Q_21268954.html Among the answer
There are a couple that are quite reasonable, and most importantly BRIEF.
Hello, Black_Cat
Bla> A circle with pixels magnified 4 times in both coordinates.
The resolution you suggested implies a vertically elongated screen. What
How do you get a 4x magnification on both axes?

There is no need to switch, it looks like the IR3Y26A chip is designed to work with RGB signals.
In any case, all the circuits with this chip that caught my eye work exactly with
RGB signals.
Unfortunately, none of the diagrams contain the names of the chip legs.

Hello icebear

And I mean the same thing: 192x4=768 Picture:

repeat 4 times in a row. And no averaging is necessary. The same thing was discussed
Previously, for 640x480, accordingly, the coefficient there was not 4, but 2, while there was
another curb.
Regarding 100Hz, I don’t see any point. Now on request
TV viewers looked at the characteristics of sold TFT monitors from 15" to 20"
and from 4:3 to 16:10, those that are on sale only in a single store -
in Ultra. So I counted several dozen models supporting 50Hz (even though
that in half of the characteristics this parameter is not indicated at all, otherwise it would have been
more). At the same time, many models marked Multimedia (not TVs)
had different combinations of low-frequency video inputs.
Conclusion: 50Hz TFT is completely easy to find, and the further you go, the more
This means messing around with other frame rates, inventing all sorts of
converters are simply Sisyphean work, because... by the time of their release you can already
will manage quite well without them. They will only be needed for junk
secondary market, and junk consumers will not invest in it.
P.S. Moreover, there have already been articles in the press about TFT for watching videos withcameras with a frame rate of ~30Hz. Technologies do not stand still, but go against the world
currents are pointless IMHO.

Dear black_cat, let me know what you mean by 'personnel'
in relation to TFT monitors? The frequency of frame sync pulses supplied to it
at the entrance or, God forbid, something else???

My screwing of a 6.4 inch LCD to a Spectrum.

Hello, Black_Cat
Finally connected my Quorum
to LCD TV Vitek VT-5005 via RGB.
RGB input signals are soldered to the chip inputs
IR3Y26A, which controls the LCD matrix.
A complex synchro signal is supplied to the video input
TV, and the TV itself switches to AV mode.
The image is quite clear, but of course on a 5" screen it is a little small,
Moreover, the border takes up quite a large part of the screen.
PS. The TV was not damaged :)

I installed decoupling resistors on the RGB inputs, which
allowed to switch to TV mode without disconnecting from the Spectrum.

2Caro: can you take pictures of what it looks like with Spec’s images?

What is the impedance of the resistors?
And now I’m thinking, maybe I can buy the same TV and remake it...

Hello caro
CARO, I wrote today on Sharp USA, and - oh horror! - they sent me a datasheet to
IR3Y26A :-)
Hello, tnt23
Question about the same portable LCD TV... Is it possible to send an RGB signal to VGA
8" TV input (so as not to interfere with the warranty TV scheme)? Unfortunately, I
Telemaster did not find the Elenberg 8" circuit diagram.
PS: I know that VGA does not imply television scanning frequencies.
This is actually why I’m asking - is it possible...
