The clock is ticking, but mine is not ticking...
ZXNet echo conference «hardware.zx»
Hello, Mikka_A
Similar tops. Colleagues, help.
Hello, All
Greetings everyone!
We have Scorp + Smook on hand.
As you know, there are realtime clocks based on Dallas 1287 (in my case 12887
).
The car regularly loses its clock. Moreover, the logic of their losses is unclear.
The belief that a dead battery is not accepted there.
For the sake of experiment, I set the clock, carefully turned off the machine, and after two days
turned it on and saw the clock ticking. That is, the battery there is strong and capable
keep the clock running.
Moreover, the loss of the Dallas smooks is not expressed precisely by the “not seeing” the chip smooks, but
namely the error - CMOS Checksumm error.
It’s just that due to the loss of the clock, in my opinion, there is a problem when loading
when you turn on the machine, that is, at the initial start, when the saved file is loaded
previously configuration.
Let me explain. I set everything up the way I need it (provided it looks like a clock
ticking), saved - in theory, as I understand it, it saves the config in kmos, that is
to Dallas.
At the next start we lose Dalla, and it turns out that mine was crying
configuration.
This is how the configuration is loaded in this situation? we don’t see Dallas, we load from
NVRAM? Or from a screw?
What do the Spectrum Gurus think?
Hello, Mikka_A
It really resets for me, I have to set everything again.
Hello, Mikka_A
Mik> CMOS Checksumm error
And does it just swear “CMOS Checksumm error” or is it really reset? Not
tried to read what is actually written in it at the moment and compare it with that
What is supposed to be written there?
Hello, Black_Cat
And I had almost the same thing, only on PC. Moved the system unit to another
room and the glitch disappeared... Strange... Maybe something fell into place when
transportation.

no
how?
Hello, Mikka_A
Mikka_A, maybe it’s because:
- we both don’t have normal (or rather, no ;)) bus buffering
- both have yellow scorpions
- Both have ZXMC too
There's a weird resemblance, I'll tell you...

You understand why CityAceE has the exact same configuration.
And he says that after purchasing a new Dapllas (we read - with a fresh battery
) - THE CLOCK HAS NEVER RESET.
so it seems to me that the dog was not rummaging in the buffer...
Scorpio people would probably get confused with this issue, then, with a massive
board production.
Hello, Evgeny Muchkin
Evg> It really resets for me, I have to set everything again.
Mine too.
and sometimes even more so - kmos not foundation.
Only turning the power off and on helps...

PS. Yesterday I tried my best to solve the problem. According to the advice of fKo (respect and
respect) - I watched what was happening with RESET. My God, horror and horror.
:v2_jawdr; :v2_eek:;
There are such packs of impulses. It’s fucked up. There are opinions that they are telling fortunes.
if the zilog eats this while it is restarting, there is nothing wrong with it
happens, then everything seems to be reset. tried to implement all sorts of different
scheme for a more competent reset, but there wasn’t enough time, they forced me to sleep (gee)
:eek; :v2_tong2:;
I'll continue my research today.

I don't have ZXMC!

I lost Dallas to PC's mother! That is, I didn’t buy it new.
But really, my watch has never reset!

The multicard is inserted into the smuk.
therefore it is not important.
although for the purity of the experiment I will try today without a multicard.
By the way, on Saturday I bought 5 motherboards 386.. ( gee gee gee: v2_tong2;
);
so there was one among them where there was a BQ3287 - a complete analogue of Dallas, but from
Texas Instruments. I implemented it, and what’s most amazing is that it works
more stable than all the others.
But it still folds...
