Hello Ronin
Ron> in general, nowadays it’s easier to install one 512kb microchip and that’s it.
That's what I'm asking about: what ICs, hemming circuits...

Yes, I would love to dig into it, but I’m not good at coding, which is why I’m asking
Maybe someone had such a problem. And I checked the percentage, ROM on the working GS they
are working.

Yes, YOU NOTICED THIS CORRECTLY, TO THE VERY POINT.
Okay, I. We have companies in Novosibirsk through which all this can be ordered at
the overpayment will be small.
And for others, how can they fight this stuff, eh............?
But how, you have to offer help to others, well, the person doesn’t have an IMS,
and you tell him “but they sell it here, you can send me the money, and I’ll send IMS”
and that’s all, and this is without deception, you need to trust people (within reason)
Okay, enough about the bad, let's talk about the bad.
Then tell me what kind of mikruhi these are and what they are eaten with.
Are they kind of like a memory?
LC321664AJ; AAA1M304P-08
Anyway, can anyone give me any information on bourgeois ICs?
otherwise I have about a hundred of them and I don’t know what kind of mikruhi they are.
Couldn't you find more detailed information on the Internet?

Hello, hardy
har> LC321664AJ ; AAA1M304P-08
what kind of body, how many legs and where did it stand? looks like a memory, but I don't know.
WBR, Ronin aka Victor Roni
Hello Ronin
Ron> what body, how many legs and where did it stand?
Basically everything was taken from CDROM and HDD and maybe from PC motherboards...
Hello, hardy
har> Yes, YOU POINTED IT CORRECTLY, TO THE POINT.

Hello, hardy
> In the instructions for GS it was made from /IORQ with Z80 through a resistor
when connecting to the Pentagon it was not needed - there were no conflicts. so first
how to cut iorq, check without it
Hello jtn
in PROFI 5.x there is an OUTIORQ signal on the connector. this is IORQ, turning off when
one of the internal devices is selected - maybe take it instead of IORQ (if there is one)
on v3)...
Does anyone have a PROFI port card? I don't know which port it might conflict with
GS #B3/BB, and GS has full decryption
Hello SMT
If you use cp/m, then there will be problems - you need the cp/m signal in the decoder
start it up, though... do iorge as it says - most likely it won’t
conflicts
Hello, lvd
To All:
To avoid creating a new topic:
Now I'm going to connect GS to the pro.
Are there any peculiarities in connection?
More specifically: is there a /IORQCE signal on the Profi v3+ system connector?
In the instructions for GS it was made from /IORQ with Z80 through a 330-470 Ohm resistor.
Who has already connected, please tell me.

Yep, there definitely is! I was thinking about him: take him, or cut off the 20th leg?
Hello timex
tim> Yep, definitely there! I was thinking about him: take him, or cut off the 20th leg
if there is a conflict with the pros’ own ports (I don’t know of any), then when
When selecting a port, this OUTIORQ will not be enabled. so it's no use. and if not
will be (most likely it won’t be, imho) then iorqge won’t be connected anywhere at all
Press RESET immediately, Roman Timofeev!

How weak is it? (IORQ -- B19 u PROFI).
