Hello Retrograde
Ret> to collet

Hello, All
My long-awaited payment arrived yesterday. The order was paid on the 10th, the money arrived
Roman on January 13th. The device was on the road for 2 weeks.
While the board was on the way, I was looking for the kit and mentally preparing for
assembling the car! As practice has shown, they are most difficult to obtain in our area
turned out to be IR23, RU7 and DAC with ADC.
Yesterday evening I started installation.
Photo 1. The appearance of the board did not cause any complaints. The board is made perfectly,
metallization of holes at a high level. In a word - a thing!:

Photo 2. Preparation for installation. All persons were expelled from the kitchen to avoid
nervous shocks.

Photo 4. The time is approaching midnight. The first jamb is that the lower IE10 is soldered in the wrong way.
Confused the series. After drinking AP6 incorrectly, I decided it was time to sleep.
By the way! It’s a shame that the first leg of the microcircuits is not marked in any way on the board.
It would be great if it were square.

People! Is it better to plug the RAM into a collet or regular connector???
Hello Costa
Cos> By the way, why are you installing a 4 MHz switch?
Well, whatever I found in the nightstand, I put it there. ;) There is also Z8400AB1
Cos> I will install CMOS Z84С006 and instead of RU7 I will probably install 1 MB SIMs.
There were also Sims in the nightstand. But, in parallel, memory chips are traveling from Kyiv, so
that I will fence the garden in loose soil. I would like, so to speak, more native. =)
Cos> As for the panels, I would opt for collet ones, although they are black
Cos> as in your photos, the panels do not cause any complaints.
I read somewhere that collets are not even recommended in this case. What,
supposedly their contact is worse. Although in terms of price, collet ones are more expensive than regular ones by exactly
twice, plus I have to wait two weeks... I feel like I’ll go to the market tomorrow, yes
I’ll buy regular stumps and use the remaining money for beer! =)
Hello Orionsoft
Ori> yes ze best
I see. I'll wait.
Hello Retrograde
I also recently received my boards. I wrote back
here: http://zx.pk.ru/showpost.php?p=75328&postcount=15
The quality of the boards is really very good.
By the way, why do you set the ztnik to 4 MHz?
I'll install CMOS Z84С006 and instead of RU7 I'll probably install 1 MB SIMs.
Regarding the panels, I would opt for collet ones, although they are black like yours
The panels in the photos do not cause any complaints.
Hello Retrograde
People! Tell me, please!
There is a need to connect a PS/2 keyboard to the AT connector. There are no adapters in the area
it turned out. After visiting pinouts.ru I found out that PS/2 differs from AT only
pinout:
AT
Pin Name Description Technical
1 CLOCK Clock CLK/CTS, Open-collector
2 DATA Data RxD/TxD/RTS, Open-collector
3 n/c Not connected Reset on some very old keyboards.
4 GND Ground
5 VCC +5 VDC
PS/2
Pin Name Dir Description
1 DATA Key Data
2 n/c - Not connected
3 GND Gnd
4 VCC Power, +5 VDC
5 CLK Clock
6 n/c - Not connected
The keyboard and auxiliary device signals are driven by open-collector drivers
pulled to 5Vdc through a pull-up resistor.
Question: If I just re-solder the connector, will it work?
Hello Retrograde
Ret> If I just re-solder the connector, will it work?
Yes.
Hello Retrograde
Ret> Please tell me the value of resistor R61. I couldn't find it.
The second sheet of the circuit where all the resistor values are 1st column, 5th row from the top -
470ohm. :v2_eek:
Hello Retrograde
Ret>
Ret> It’s also not entirely clear with RS2. Solder in the 8th resistor (no assembly
Ret> found - I sculpt on loose powder)? This is the one hanging on the 9th leg
Ret> assemblies.
If the assembly is not used, then there is no need to solder the first and last resistor
(i.e. 2 leg and 9 leg assemblies). If an assembly is used, then there is no need to solder 9
leg, bite it off.
Hello, CHRV
CHR> Second sheet of the circuit where all resistor values are 1st column, 5th line
CHR> top - 470 ohms. :v2_eek;
U,; yo! Really! But I didn’t even notice the elephant.
Hello Retrograde
R61 - 470 ohm, the nominal value is indicated there.
Instead of RS2, 6 resistors are enough, although I installed assemblies for myself
Hello Retrograde
R61 - 470 it is there on the list.
Hello Retrograde
However, yesterday I soldered the device. Still without blocking capacitors, without
configuration jumpers. Those. "raw" still. BUT, curiosity got the better of me and
applied +5V to the board. :) Naturally, I pulled out all the cases from the panels (which
possible).
I felt each microcircuit - cool. I measured the voltage and it doesn't drop.
Then, I installed everything except the disk drive controller and ADC, it did not supply 12V.
Turned it on. The processor is slightly warm. And the HL8 also got hot. Not much. Those. by
it feels like 30-40 degrees. Approximately. Maybe less. This is fine?
Hello Retrograde
Ret> The processor is slightly warm. And the HL8 also got hot. Not much. Those. by
Ret> sensation - 30-40 degrees. Approximately. Maybe less. Is this normal?
Normal
Hello Retrograde
Ret> However, it started. Started the first time! :) !
Who would have thought! :v2_clapp;
Ret>; Today I will install the remaining memory on the second floor and solder it on
Ret> blocking capacitors.
Don't forget to make gaps between the microcircuits of the first and second floors.
Ret> While working, I noticed the following things: HL8 heats up (Roman Chunin
Ret> answered that this is the norm), RU2 (quite strongly), IR17 are heating up. But
Ret> the computer is working, so this is the norm.
Yeah, that’s not surprising for the 155 series - it warms up well.
Ret> The microprocessor, despite the fact that it is 4 MHz, is excellent
Ret> works in turbo mode. By the way, how to save boot settings
Ret> menu?
This is a question for Max.
Hello, CHRV
CHR> Is the cable connected correctly? :) check
what cable? I hook the speaker head to pins J17 and J15 - that's it
Gut, plays. But J17 and J16 are noisy.
Another question: please throw the z80totap utility at me.
Hello, CHRV
Yes! Forgot to ask:
In one of the channels of the output stage (built-in UMZCH) sound is heard, it’s easier
speaking - noise. What could it be? The connectors are soldered to the op-amp.
Hello Retrograde
Ret> Yes! Forgot to ask:
Ret>
Ret> In one of the channels of the output stage (built-in UMZCH) sound is heard
Ret> in other words - noise. What could it be? The connectors are soldered to the op-amp.
Have you connected the cable correctly? :) check it out
Hello Retrograde
Ret> what cable? I hook the speaker head to pins J17 and J15
Ret> - everything is humming, playing. But J17 and J16 are noisy.
Well, I think that you just confused J17 with J15.
If it doesn't help, you need to smoke the circuit and check the output stages.
Hello Retrograde
Ret> By the way, how to save the boot menu settings?
Ret>
Look in the boot menu itself in the "Service" section. But if you only have 512Kb
memory (as can be seen in the photo), then this is pointless, since the settings are saved
to page #38. So quickly add up to 1024Kb!
Hello Retrograde
Ret> What needs to be shorted for the drive to read and write a 720 KB floppy disk?
seal the double-thickness window of the floppy disks. they are also on other specs
will be read =)
Hello Retrograde
Ret> I.e. After turning the power on/off, will the settings be reset?
Yes. But, since the point of using vTR-DOS is to call it from under the OS
(which (at the moment - TASiS) pre-loads the TRD image into RAM), then,
in principle, you can write a utility for the system that will configure itself
all parameters (vTR-DOS has the necessary entry points) via the command line. like this
the utility can be attached with the necessary keys to autorun in the file
AUTOEXEC.BAT, and then all the necessary settings will be automatically installed
at OS startup. I (what a coincidence) am planning to do just that in the near future
create such a utility.
Hello Costa
Cos> Or maybe it was possible to save the clock in CMOS? Attach them
Cos> not a problem now.
So if there is a clock (for example, in ATM-3), then there is no problem. And for individual
cases to do (especially since those who do not have CMOS will do it) - does not have
sense.
Hello, The Exploited
I'm beating myself up! I've noticed a bad habit lately: just
- straight to the forum. I Googled it and found everything I needed. Indeed,
I taped up the window and just formatted a 720 KB floppy disk for XP. Also, I found
scrap Z802TAP. I'm posting it, maybe someone will find it useful.
File: z802tap.zip http://zx.pk.ru/attachment.php?attachmentid=4606
Hello Costa
The answers are more than comprehensive.
I'm getting ready to connect the drive. I am holding in my hands a Panasonic JU-256A067P, 3.5".
On the bottom side of the device I see contact pads in the amount of 5 pieces,
signed from left to right: ZP, TB, T2, T1, GND.
What needs to be shorted so that the drive reads and writes a 720 KB floppy disk?
In advance, thank you for your answer.
Hello, Maksagor
Ret> I.e. After turning the power on/off, will the settings be reset?
> Yes.
Or maybe it was possible to save the clock in CMOS? They can't be attached
problem now.
Hello, Maksagor

Anyone who wants it to be stored conveniently will install it for themselves. It's not that difficult.
Hello, Maksagor
That is Will the settings be reset after turning the power on/off?
Hello Retrograde

It is through this revision. Because the keyboard controller is a bit, but WAITit
comp. In other cases this is completely unnoticeable, but when working with tape -
fatal. Input - put a switch that turns off the controller when necessary...
Hello, Maksagor
Yesterday I soldered the memory to 1024 KB. Now, when loading, CP/M shows 1024 KB!
:eek; Installed; blocking capacitors of 1 Mf for 3-4 microcircuits. Computer
became more stable: turned on and off the soldering iron, refrigerator plugged into the same
tee - everything is fine. Doesn't crash, doesn't hang.
But the problem with loading from a tape recorder was not solved. Made improvements
(see above) - when you switch the toggle switch, the machine freezes, but the loading is for the life of you
doesn't happen.
Maybe this is due to the fact that the WAV recorded on CD-R is not
matches the original? I converted it using these utilities (see attachment). If not
difficult - check whether these vava loads on your reals.
File: SpecUtilz.zip http://zx.pk.ru/attachment.php?attachmentid=4608
Hello, CHRV
Unfortunately, the only instrument I have is a multimeter. Maybe there is some
voltage standard?
With the "frieze", naturally, there will be no stripes on the curb? Those. wait for the end
download and turn off the toggle switch. In this case, the download process will not be displayed.
P.S. I also gave up tape recorders. Now I use CD and vinyl.
Hello, Maksagor
Is it normal for the car to freeze? After switching the toggle switch.
I just tried to load Spectaculator from wav, everything is fine. loading.
This means there is something in the hardware.....
Hello, Maksagor
Hmm... Here's what I found:
When using an IBM keyboard, you can operate the tape recorder using
using a double toggle switch, with which you need to apply + 5V to the signals
KEYRDT (D100.13 or D103.3) and W_ON (D71.2). You need to switch the toggle switch to +5V
only while reading from the tape recorder, restoring the position of the toggle switch in
previous position after reading. In addition, you must go to SINCLAIR
in mode.
And I connected D100.13 and D103.3. Although..... Looking at the diagram, it doesn’t seem like it should
influence...
Hello, CHRV
CHR> Uh-huh, check the TAPEIN signal. Maybe the level is not enough, maybe something else...
CHR> I probably stopped using tape recorders in 1993.
CHR>
CHR> By the way, the computer should not be in TURBO mode!
By the way, about the turbo mode - in the mid-90s, back on the ATM-1, I booted with
tape recorder in turbo mode - I also had a turbo button on my mafon, I turned it on
turbo on the mafon and on the computer and loaded at an accelerated pace. By the way, it loaded
even better quality (the “tape loading error” popped up an order of magnitude less often).
Hello Retrograde
I can’t check it personally - I don’t have a tape recorder to connect to, and
cassettes with programs too...

That is? What's the problem? You start the floppy disk system (via regular
TR-DOS with the RUN command), and then work with the same floppy disk! Or you have everything
is copied, but these three files refuse? And the floppy disk format is normal - iS-DOS
800Kb.
Hello Retrograde

Actually, they SHOULD be there. Look better... The .blk screw driver files themselves can
have different names (to configure through HDD_TUNE they must be respectively
rename to HDD_mART.blk). And everything else should just be under your own
names...
Hello, Maksagor
The thing is that I want to put the axle on a screw. And on the boot floppy disk these

Hello, Maksagor
U-R-A-A-A!!!! It started!
A miracle has happened! For the first time in my life I installed an axis on a HDD under Spec! Cool! All
flies. Yesterday until 2 am I was transferring images from floppy disks to a screw.
Thank you very much for ATM and for the OS to everyone who took part in the development of hardware and
writing software.
And, traditional question: For example, I work with Alasm, which runs with
image. I worked, saved the changes - apparently in RAM. Is it possible somehow
make changes not to RAM, but directly to the TRD image????

Hello, Maksagor

Will it be possible to save?
Hello Retrograde
Ret> As I understand it, do you need to ask Max? :)
No, not me. :)
In general, what don’t you like? Saved the changes to a virtual floppy disk,
I went back to the OS and by pressing one key I dumped 640Kb of RAM into the image...
Hello Retrograde
Ret> =) I expressed my idea incorrectly. This was meant when developing a new

The fact is that the current version is independent of the OSes used.
In principle, you can make a version of TRDOS, which contains a sign
sectors in which the image lies - and upon a certain command, throw everything into these
sectors.

I like everything. But! For example, I am writing a program, periodically saving changes to
source codes. The changes, of course, are saved in RAM and, BAM, the lights go out - all
work well. And if it was written on the screw right away....

Install an uninterruptible power supply. In general, it’s time to switch to iS assembler and
