Help me find a diagram — ZXNet «hardware.zx»

From Slavik Tretiak To All 29 December 2005

Hello, BaguM wow! give me two. We're all telepaths here, I guess. boards that are green at the bottom, a common memory field on RU5B and a buffer for the keyboard on AP3 there are countless. The only clue is the inscription. How about attaching a photo?

From Vadim Maleev To All 11 January 2006

Hello Conan Similarly, there is a circuit from 64k synthesis or from another modification: EY3,031,724 E3 developments by comrade Filatov (copy of the factory diagram). Memory in the diagram for 8 RU5 and ROM 2 RF2... and a lot doesn’t add up - there’s no m/sx, or other type...

If you find it and there is no scanner, send me a copy by mail, I will scan it and give it to you Conan.

Hello, CHRV I'll try to go to Signal next week, maybe I'll ask them for more filats it works... then maybe they’ll give you a factory frame too

Hello, BaguM Bag> http://ard-md.com/images/MotherBoard.jpg Bag> http://ard-md.com/images/MBLayout.jpg Bag> http://ard-md.com/images/FDDController.jpg DEAR!!! I'm about to cry and get on my knees at the same time. Thank you very much!!! Is there a circuit from Sintez-M? Mine was produced in 1991 (judging by passport), I bought it in April 1992. I have two of his schemes, but both look like errors, but I would like a normal one. PS: Kostya, pay attention to element D8 :)

Hello, BaguM Thanks again for the schemes! Bag> Similarly, there is a circuit from 64k synthesis or from other modifications: Bag> EІ3,031,724 E3 developed by comrade. Filatov (copy of the factory diagram). It would be very interesting to see this diagram. Perhaps this is an earlier one version. Andreas (icebear) has two different circuits (one with error) and we discussed their features and differences for some time by email (in particular DD6). Therefore, any additional information will be very helpful.

From Vadim Maleev To All 15 January 2006

Hello icebear I can scan it... but it’s blue and pink, so it’ll be 3-4 meters... but In general, I wrote what type I have... it’s factory, but I can’t tell if it’s the latest one to say exactly. :( I don’t have a diagram at hand so tomorrow

From Konstantin Sviridov To All 16 January 2006

Hello icebear Here are my thoughts on identifying Sintez schemes. Firstly, let us remember that there were three models: Sintez (white case, keyboard with a cursor, which also has a key ). Sintez-M (black case and keyboard like the ZX-Spectrum+) Sintez-2 (black case and keyboard like the ZX-Spectrum+) The two variants of the Sintez-M circuit differ slightly (essentially by one element). No photo of the board and computer has been found yet, but there is a wiring diagram. The Sintez-2 diagram published by the respected BaguM completely coincides with the existing ones photos of the board and computer. Scheme of the "Synthesis" modification: EBN3,031,724 E3 also published by BaguM differs from the Sintez-M and Sintez-2 schemes. But in this diagram to the keyboard connector Reset signal is output. And on the diagram itself the name is indicated as , without all sorts of <2> and . Therefore, I think that this is the scheme of the first Sintez. By the way, the pinouts of the system connectors are different for all Syntheses, and differ from branded cars (although it is logical to assume that if in models <2> and copied the body of the proprietary model, then the connectors could). Mention that Sintez-2 is a modified Sintez-M can be found for example, from Denis Tsigankov: From: Denis Tsigancov["http://groups.google.com/groups?hl=en&oe=KOI8-R&q=author

they introduced a synchronous generator of the main timing signals (D38). In the photographs provided by Costa, the release date of Sintez-2 is on the bottom of the computer indicated as 93, which also coincides with the information of Denis Tsigankov. ice> in the course of Sintez 2 was not a “continuation” of Sintez-M, rather the opposite. ice> IMHO, the Sintez-M scheme is more “civilized” than Sintez 2.As for the idea about “civility of circuit design,” I didn’t understand it, please explain, please.

Hello, BaguM I went to Chisinau and brought Sintez-2 in the original box and with a full documentation, including diagram. If anyone really needs it, I can digitize it somehow.
