Hello, TmK
I don’t presume to judge everyone, but CPU options 1 and 2 are suitable as
to potential democompo participants.
Hello elf
TmK> At the moment there is a choice: which real to use as
TmK> demo machines.
TmK> There are three options:
TmK> 1. Standard Pentagon 128K + turbo_ay_fm
TmK> 2. Pentagon1024sl + turbo_ay_fm
TmK> 3. ATM-Turbo + turbo_ay_fm
TmK> I myself am more inclined to either option 1 or 2 (namely 3 is a perversion)
2! Because I’ve already seen enough of the pictures from the crookedly assembled “1” (the brightness was
oh...yep, black, etc. stripes on the boundaries of attributes... and it’s not a fact that
this will not happen again when using "1").

Hello, CHRV
2 KOE; acquired; bare board, there are a couple of questions: what current does the second one consume?
pleasing? I mean, I have stubs at 3.3, but I don’t want to mess around with transients.
And one more thing: what series of small items can I use?
Hello KingOfEvil

Nothing problematic, all signals HS, VS, BL are built using HL8 logic - therefore
By replacing this plate everything can be solved.
Hello KingOfEvil

everything is fine, one of the 2 boards I bought from you was just for him
Hello KingOfEvil
I purchased this device in a place with an ide controller and a keyboard controller with
mouse and Com port! Thanks to Alexey and Camille!
Here are questions for those who already use it:
when entering the basic 48 mode, make border 4 and a red stripe appears with
at the top at the end of the screen, two centimeters thick, red, make a border 5 color
it also changes to a bright shade of red, everything else is filled in correctly
the color it should be.
do not enter menu 128 like on a regular Pentagon
how to connect a tape recorder, there are a lot of cassettes and I don’t want any more pussy
use for translation.
I would like to transfer a lot of floppy disks to a hard drive (it is determined via wdc 105, but
how to copy onto a screw?)
according to the diagram about the red color, the RGB sync signal, as I understand it, comes from the alter,
maybe it's a firmware issue? An extra step is visible on the oscilloscope when switching
border colors.
and in principle I’m very pleased, if you help me figure it out I’ll be very happy.
Hello Vitron
Are you already using the Kamil multimap on the Pentagon 1024? Works fine

Hello Vitron

The multicard blocks the native keyboard port, which also includes the read bit from
tape recorder.
If you really need it, I can make this bit go through the multicard.
In hardware, you just have to connect the output of the tape comparator to one of
free Mega pins.
Hello caro
Just now it dawned on me that because of the multicard, goodbye Vicom modem ;) not really though
then he is needed, as they say ;)
Hello KingOfEvil
Gluk is not “imprisoned” anywhere. When you press U, it culturally goes to the 0th address of the 128th

Everything would be fine, but this comparator is not available on 2.2 boards. Was removed for
unnecessary. I didn’t expect that anyone would want to use a tape recorder.
Hello caro

Yes, just for fun. Why do you need a tape input, since the board
Attached was a huge archive of software, one can say with 99.9% probability that
that everything that is on your cassettes is there.
Hello KingOfEvil
A tape input is needed for compatibility; there are several cassettes with
programs that he himself wrote and a friend wrote, they competed with him back in school,
I found them, the download is cool.... plus the nostalgia is in the hardware, not in
emulator. Moreover, my son asks how to connect the tape recorder, he likes how
beeps and loads. for now I don’t want to trust him with programs on the hard drive, and
It’s still difficult for him, but the tape recorder is just right...
...if there is a new development, it should be improved without any
exceptions of unnecessary blocks.. I think so. It might come in handy!
Hello Vitron
Another question, which circuit was previously the best in terms of reading stability?
Hello KingOfEvil
Kin> So, just for fun. Why was a tape input needed, because

Kin> 99.9% claim that everything that is on your cassettes is there.
Many people are porting tape versions (for example, Chronosoft and many
bourgeoisie use only new tape games).
Well, sometimes there are rare cassettes. There are games that work in multiplayer
through the tape output.
Hello Vitron
Vit> ...if there is a new development, it should be improved without any

I tried to make the circuit as simple as possible, which was rarely used
excluded.
Hello Vitron

I don’t know, I loaded from a tape recorder once in my life, and even then it was fine
experiment. My first spec already had a disk drive, so the tape era
I didn't find it.

Vit>
It won't work, because... the start after reset comes from the 0th page of the ROM, which in
Pentagon-128 is not used. Now there is Gluk Reset Service.
But if you insert the ROM from P-1024sl 2.2 into the P-128, it will work.
The location of the basic/TR-DOS firmware is the same.
Vit> I have an oscilloscope S1-64, it’s heavy..
And I also have a C1-70, it weighs 25 kg and takes up half the table. I've been wanting it for a long time

CHRV makes a VGA converter. But he says that it’s unlikely to be at the Pentagon
work, because of the notorious 320 lines on the screen. If the question arises about
incompatibility with the VGA converter, then I will have to write firmware for the FPGA for
screen of 312 lines. But then compatibility with the Pentagon is lost, because in
interruption will no longer fit 71680 cycles, and various demos that are for this
calculated, will fail.
All sorts of cunning methods based on turning on the turbo on the last 8 lines of
my opinion is hardly acceptable, because Linearity in time is immediately lost when
execution of programs and it will be impossible to play digital music. Although now
revived the General Sound project, and the need for playback
digital music using processor means is no longer required. In general, we'll see how they go
affairs. In any case, you need to wait for the VGA converter to appear.

Hello KingOfEvil
About the link to the description of the Pentagon 1024 sl 2.3, the three is just a typo.
Hello KingOfEvil
Listen, here's what I thought about the controller. There is one more suggestion. U
I have an idea to power the Pentagon from an ATX PSU. But I would like not to toggle it
turn it on manually by sending 0 to PWR_ON, and programmatically. For this I want to collect
a circuit on a small Atmel to which the power button and LED are connected
(will indicate by blinking when the machine is turned off that it is connected to
power supply :-). I also want to add a PWR_CTRL signal to it when moving from 1 to 0
the power will turn on or off. The idea of this signal is to
go somewhere on ZX-BUS, there seem to be free contacts there and in
In addition, bring there the duty +5V from the power supply. Then it will be possible to do, for example,
turning on/off the computer using the keyboard, turning off the computer
programmatically, if you make a control port on the board. And do it on the controller itself
a couple of jumpers, one will switch the power, i.e. powered from +5V or from
duty +5V, the other will cut off the PWR_CTRL signal from the controller. Here.
But I wanted to ask about the keyboard controller, will there be a possibility
fill in the keyboard layout?
And one more thing I wanted to say, is it possible to make a controller board without
high, i.e. so that it fits into slim cases. :-)
P.S. But the watch is very necessary, otherwise you will have to pay extra money for it... :-)
Hello jager
jag> But I wanted to ask about the keyboard controller, will it be there
jag> ability to fill in the keyboard layout?

I will post the source code for the MK firmware, there will be a conversion table there. Anyone can
Match the scan code with any Spectrum key.
jag> Yes, and I also wanted to say, would it be possible to make a controller board

You just need to take into account that the KR1878BE1 is almost a complete copy of the PIC16F84.
When they first appeared, I was also happy and tried to apply
them in your product instead of PIC16F84, but after out of 5 received
3 samples did not work immediately, I abandoned this idea.
So in the final version I think you will have to install either PIC16F627 or
PIC16F628 :)
By the way, they are also much cheaper in price.

At the initial stage, when mastering the production of something new, there is always
it happens. In addition, they might not work due to the fault of those who sold them,
for example, if he damaged them with static electricity. I'm very often
salespeople in stores bring you to a pre-heart attack state by groping
finger everything, even static-sensitive CMOS microcircuits.
You make a remark to them, and they get offended, saying they are picky buyers. But
Then you'll guess whose fault it is that the microcircuit doesn't work.

If the flash drive is fast, then it may click on the wrong address due to
DOS signal delay (address line A15) compared to other address
signals. For UV ROM, all this is uncritical, but for flash drives it can be excluded from the circuit
C9 and C2 (I initially counted on UV ROM).
Yes, but is the ROM flashed correctly? If it’s wrong, then no more manipulations
won't help.

If they are closed, a non-maskable interrupt will be generated (button

I meant the location of the pages in the ROM, if they are mixed up, then you will have
video effects + freezing (in the worst case). Don't forget that the start comes from 0

firmware, it is in this thread. And here's the latest version as a bonus

One more question for everyone.
Who else in V.Novgorod has a Pentagon 1024sl?
Hello KingOfEvil
I have a question, will the hard drive controller work if I have one more
Will I insert the controller?
There is an idea to use a hard drive, cd rom, adapter CF ide, SD ide... instead
those devices that are still being assembled or debugged..
that is, there will be three devices, therefore two controllers.
I don’t want to give up the screw and I don’t want to stick a cable into the adapter either.
Hello Vitron
The glitch does not support loading is-dos from a screw, but in principle it can be registered
your own bootloader, which must be compiled to address #6000 and written to
screw from sector 3 (numbering from 1), but in this bootloader you can do whatever you want
whatever, load is-dos or something else. By the way, I wrote such a loader, but not
finished yet, not enough time...

You don't need to switch the power supply, but OE (or CE). Moreover, when the RAM is turned off, OE (or
CE) must be pulled up to +5V through a resistor (well, for example 10k).

Well, if you correct the decoding of the second controller (you will attach it to other

Hello skyther

This means you need to look for errors in installation or faulty elements. If basic48
starts, then you need to look for glitches in switching ROM pages. Look
with an oscilloscope the higher addresses (A14, A15) on 27512, and you also need to trace
passage of all signals through DD8, DD10, DD11, DD12. Just in case
try flashing UV ROM.
What also confuses me is that the first version of the firmware does not work. It's different from
the latter only in that the computer, after turning on the power, starts immediately in
turbo mode, and in the latest version the turbo turns on with a delay of several
beats The first version simply cannot work.

It's a terrible example of design, I'm not even talking about the price. There was chip and dip
the size of a DIP. In short, there is no point in purchasing adapters (with their
prices), they are clearly for other purposes. It’s definitely better to immediately take a small circuit diagram to
DIP package, or solder PLCC directly to the socket.
Hello skyther

I was connected to a Panasonic TV via a composite output, when desoldering
quartz, so that color does not work, shows black and white perfectly clearly, with
sealing and setting, there is a blur precisely in color (like everyone else, a comb).
I connected via S-Video, removing the condenser from the output to the mixing input of the microcircuit and
Having connected "Chroma" S-Video from this output, the color became good, but there is interference
in the form of colored noise, small. For now I decided to install another Pal encoder, from
NedoPC... judging by the pictures the image is even better quality on S-Video than
I got it.

assembly of P-1024sl boards. I have now temporarily suspended accepting new orders.
I am collecting those already accepted.

Why not take up the task of “improving” what they did in Peters?

Hello, WingLion
/// about the TV brand, we meant its full nomenclature number (written
on the back of the lid) I’ll look at the diagram to see if anything is missing or spoiled.
You can also check by connecting some signal to the sync
VCR...
It seems to me that five volts is not enough to switch the lock or the wrong one
the contact is connected to this voltage.
Hello, falanger
If the image appears normal when you switch channels, then the problem is
in blocking video on the TV itself.
Please, the brand of the TV, then it will be clearer what and how..

TV "Vityaz" with IR remote control. The remote control I use is RCM type from imported
telly.

By the way, yes! Great idea!
Hello KingOfEvil
Kin> Where can I find information on it? On http://winglion.ru/sprinter/ not
Kin> found.
So far it's only on my hard drive (and on DVD).
I will post it, but not all at once, now I’m posting about the Sprinter little by little
info.
I'll have to figure out the CAA converter myself in the near future, because
the TV at home does not work, and only on it can you check the Sprinter boards,
those that are assembled, but not configured.

Did you finish it?
I remember Vasya Ivanov paid the Peters ($75), but never received anything.
Hello, CHRV
CHR> Did you finish it?
CHR> I remember Vasya Ivanov paid the Peters ($75), but nothing was done
CHR> received.
The board I made is on the table.
Now I don’t remember exactly where I stopped.
There were some problems, but it showed.
On cathode ray monitors.
Ah... I remembered. It didn’t want to be shown on the LCD at all.
But now I know why. We have to take it on and finish it off.
All you need is time, but you also need time to work...
Regarding the money in Peters, I’ll ask what’s going on...
Hello, falanger
fal> a) What type of speaker is “Speaker” and its second pin is soldered to GND or
fal> where?
fal>
Not a speaker, but a linear audio input of a TV/monitor. Yes, and then only if
not used by YM. In general, the speaker is mixed into the YM outputs.
fal> b) next to the wires "R-G-B", "SYNC", "VIDEO" there are two wires "LEFT"
fal> and "RIGHT". What is inferred from them?
fal> And what is output from "S_LEFT" and "S_RIGHT"?
fal>
I already wrote about this, see above.
fal> a) where and how are “Magic0” and “Magic1” soldered?
fal>
Likewise.
fal> Besides “Magic” and “Reset”, are there only keyboard-joystick(s)?
Yes.
Hello KingOfEvil
2KOE: Alexey, can you make a button for the turbo? or at least an indication...
Hello jager
jag> so my Pentagon started up, yesterday I unsoldered the sim and started to launch.
jag> started right away, however, Lyosha, like on Monday you have a scarf
jag> tested with a flash drive, did not want to start without a finger. deleted
jag> Conders C2 and C9 still don’t want to start.
Try to return C2 and C9 back and put a capacitance of ~50..100 pF between leg 22
DD5 and ground. Then the ROM address will be captured clearly.
Hello skyther
sky> 2KOE; Alexey; can you make a button for turbo? or at least
sky> indication... Or, at worst, firmware without a turbo at all...
It is impossible to make a button for the turbo, because... mode control signals
turbo/non-turbo sit inside the FPGA and cannot be pulled out. Can be done
indication on bit 4 eff7. Firmware with disabled turbo in the application (just
recompiled the existing source, setting bit 4 eff7=1).

A very serious omission :(
Hello, The Exploited
KingOfEvil, what if you need to switch the turbo while working? A button is needed
intended! :)
Hello, The Exploited
Kin> by hard setting bit 4 eff7=1
Maybe it’s better to do the opposite: so that the turbo turns OFF when the bit is reset? And in
enable the menu if necessary.
Hello, Evgeny Muchkin
Evg> A very serious omission :(
Why do you need a button? You can turn off the turbo from the start menu with one click
"W" (no worse than the "turbo on/off" button). Turbo disabled mode is needed
only for compatibility with old software, as well as with multicolor effects.
In all other cases, the faster the better.
Hello KingOfEvil
a button is needed. I even have two of them on my profile (they work differently) + software
switching like in a scorpion
