From Andrey Alexandrovich Titov To All 9 March 2006

Hello, All Is there an internal ULA circuit in the internet nature?

From Dmitry Demyanenko To All 9 March 2006

Hello Titus On the same site where there is a diagram of flying saucers and single-pole magnets :)

From Stanislav Lomakin To All 9 March 2006

Hello hero her> On the same site where there is a diagram of flying saucers and single-pole her> magnets :) eh, many people searched for this site... and came back empty-handed. except those of course, who is MISSING FOREVER :) [http://zx.pk.ru/showthread.php?t=2259] attachment has already been deleted :(

From Victor Ronin To All 9 March 2006

Hello, CHRV CHR> What do you mean by internal circuit? photo templates for ASIC probably :D

From Andrey Alexandrovich Titov To All 9 March 2006

Hello hero her> On the same site where there is a diagram of flying saucers and single-pole her> magnets :) That is no one ever split it??? :v2_conf3: :v2_jawdr:

From Chunin Roman To All 9 March 2006

Hello Titus Tit> Is there an internal ULA circuit in the Internet nature? The question itself sounds kind of strange! What do you mean by internal circuit?

From Dmitry Demyanenko To All 9 March 2006

Hello Ronin Ron> photo masks for ASIC probably I think about a dozen Tit> That is. no one ever split it??? Ask Conan which is the most accurate clone on disc, here you go approximate split

From Victor Ronin To All 9 March 2006

Hello Titus Tit> I can make an approximate one myself, I need an exact ULA from 48 spec. No. This is SRL internal documentation.

From Andrey Alexandrovich Titov To All 9 March 2006

Hello, CHRV CHR> The question itself sounds strange! CHR> What do you mean by internal circuit? The internal circuit is the internal circuit. Those. triggers, counters, valves, etc. In short, I need this for a 100% accurate understanding of its work.

From Andrey Alexandrovich Titov To All 9 March 2006

Hello hero her> Ask Conan which is the most accurate clone on disc here her> and an approximate split for you I can make an approximate one myself, I need an exact ULA from 48 spec.

From Vladimir Kladov To All 9 March 2006

Hello Titus Multicolor for the proprietary ULA has long been split and is supported in emulators 100% sure. Those. go to the description of multicolor for branded Spectrums 48, 128, 128+, 128+2, 128+2A/2B (2A=2B, just 2B - Spanishized ROM, as I understand it), 128+3, Timex 2048/2068 (aka Spectrum SE). Everything is planned to the beat. Supported emulators Real Spectrum, Spectaculator, Spin, EmuZWin, Klive, SpecEmu (and in to some extent, perhaps several more). By the way, Real Spectrum even has choosing the ULA type, they injected it very carefully when they found a difference.

From Konstantin Sviridov To All 10 March 2006

Hello, Vladimir Kladov Vla> 2A=2B, just 2B - Spanishized ROM, as I understand it Differences between and : different countries of manufacture. In addition, models sold as Action Packs. There were Spanish-language ROMs in both +2 and +2A.

From Andrey Alexandrovich Titov To All 10 March 2006

Hello Conan Based on all of the above, I have 3 questions: 1. How many fundamentally different types of ULA existed and in which branded speck which one of them was? 2. More specific links to the docks on Yule? :v2_rolley 3. How much can you buy a branded Spec 48 for now (on eBay or somewhere else)? A also other versions of branded specs, but with a different spinning top?

From Alexander Shabarshin To All 10 March 2006

Hello Titus Tit> How much can you buy a branded spec 48 for now (on eBay or else Tit> where)? I bought a working ZX Spectrum + on ebay for only $2. True, I paid $68 for shipping from UK to USA... :v2_eek:

From Nikita Alexandrovich To All 10 March 2006

Hello Titus Tit> to Russia how much do they cost? Yes, how much and to America if not more expensive :) I ordered something from Germany there something like this in Germany 15-18 euros fifty dollars to Mother Rossi and across the endless expanses another 500-600 rubles (I ordered the laptop from me :))

From Andrey Alexandrovich Titov To All 10 March 2006

Hello Shaos Sha> I bought a working ZX Spectrum + on ebay for only $2. Sha> Sha> True, I paid $68 for shipping from UK to USA... :v2_eek: For $2? How's that? How much does it cost to send them to Russia?

From Andreas Kaiser To All 10 March 2006

Hello Shaos Sha> I bought a working ZX Spectrum + on ebay for only $2. Sha> Sha> True, I paid $68 for shipping from UK to USA... :v2_eek: That's the point :) I bought mine for 27 euros including shipping. 2Titus: ebay is an auction, no one will tell you specific prices. On my own From experience (observations on ebay.de) I can say that ordinary Sp 48 go somewhere behind 10-20 euros, Sp 128 - a rarity, both English and Spanish, respectively they go for somewhere around 60-100 euros. Sp 2/3 is not exactly a rare thing, they go around the area 30-70 euros. You should ask the seller specifically about the shipping amount. Price depends on how the package will be sent (with insurance, without, by land, by air, etc.). Shaos' example (for $2) is an exception to the rule. Although on In English ebay the ZX Spectrum+ is not particularly “listed”. By the way, now there (ebay.co.uk) "sale" is underway - one bastard is either a mine with Spectrums I dug it up, or SLR offended me 20 years ago, but now it’s selling Spectrums there in batches. By the way, another option is www.sintech.de, their prices are specific (in the sense of not change), you can ask them about shipping to Russia and buy there.

From Alexander Shabarshin To All 10 March 2006

Hello Titus Tit> What is the main way to pay on eBay? Probably some plastic Tit> do I need to create cards or what? PayPal - they DO NOT work with Russia...

From Andrey Alexandrovich Titov To All 10 March 2006

Hello icebear Then I’ll ask the public again, who are aware of how many types of ULA there are existed, and what models did they come in?

From Andrey Alexandrovich Titov To All 10 March 2006

Hello icebear ice> By the way, another option is www.sintech.de, they have specific prices (in ice> meaning they don’t change), you can ask them about shipping to Russia and ice> buy there. .de? I would ask, but I can’t speak German... What is the main way to pay on eBay? Probably some plastic cards do I need to start it or what?

From Victor Ronin To All 10 March 2006

Hello Shaos Sha> PayPal - they DO NOT work with Russia... but rupay, webmoney and probably all sorts of others are successfully transferred into it.

From Andreas Kaiser To All 10 March 2006

Hello Titus Tit> .de? I would ask, but I can’t speak German... What's stopping you from asking in English? Tit> What is the main way to pay on eBay? Probably some plastic Tit> do I need to create cards or what? Transfers, PayPal, cash on delivery, cards. Depends on the seller.

From Andreas Kaiser To All 10 March 2006

Hello Shaos Sha> Well, if I lived in the UK or bought a Spectrum in the USA, then for shipping Sha> I would pay pennies - but they don’t sell Spectrums in the USA and I don’t live in Sha> UK... This is all understandable, that’s why I wrote it - that’s what I’m counting on. On ebay between competitors Recently, the practice of luring customers by reducing prices has begun. on the product and returning this money through the mailing list (people always look only at stage). If you bought from a private person, then most likely there is no such trick pulled it off, although you don’t know how this comrade sent you You won’t be able to check the parcel either (read I told you one price for mailing, sent for another).

From Alexander Shabarshin To All 10 March 2006

Hello icebear ice> That's it :) I bought mine for 27 euros including shipping. Well, if I lived in the UK or bought a Spectrum in the USA, I would pay for shipping a penny - but they don’t sell Spectrums in the USA and I don’t live in the UK...

From goodboy To All 10 March 2006

Hello, Vladimir Kladov regarding delivery from auctions/stores, you can try http://pregrad.net/ more guarantees that the seller will not cheat.

From Vladimir Kladov To All 10 March 2006

Hello Titus In my opinion, all types are listed in the RealSpec config. If you don't have RS, I can run... On the WoS pages in the documentation sections something is written, but I didn’t seem to find any analysis of the names of each ULA there. It is assumed that on Each branded car has its own type, and they are _very_ compatible.

From Konstantin Sviridov To All 11 March 2006

Hello Titus Tit> how many types of ULA existed, and what models did they come in? Programmatically indistinguishable: ULA in ZX Spectrum issue 1 and 2 ULA in ZX Spectrum issue 3-6 ULA in ZX Spectrum 128 and +2 ULA in ZX Spectrum +3 and +2A/B There are four types in total. Timexes are a separate issue. I’ll add that the idea of buying these models for testing, in my opinion, is Quite clueless. Exactly the same as finding the “internal ULA circuit”. For accurate emulation of specified types (ULA) has almost all the information. On the forum, By the way, it was published. But other hardware , for some reason often missed. This is an emulation of , of the contents of fast memory when forcing the IR register and other features. The question is whether it is necessary repeat all this? If yes, then for what? After all, accuracy is important when emulating operation of existing software, and not the to distinguish an emulator from real. Let me give you another simple example. When working ZX Spectrum issue 1-2 in addition to slightly blurred image on the TV screen, a kind of moire appears and color distortion of the picture. Is it possible to emulate ;) ? And is it necessary?

From Andrey Alexandrovich Titov To All 11 March 2006

Hello icebear Thank you all very much. Searching through the documentation and emulsion configs

From Alexander Shabarshin To All 11 March 2006

Hello Ronin Ron> but rupay, webmoney and probably all sorts of things are successfully transferred to it Ron> others. to transfer something to PayPal you need to have PayPal, and if you don’t credit cards with a Western home address or checking an account in a Western bank - then I don't care who will give it to you ;)

From Yuliy Trunin To All 11 September 2006

Hello, All Guys, tell me what is the difference between the “street” and that garden of microcircuits, which is used, say, in Pentagon 128? :v2_cool:

From Andreas Kaiser To All 11 September 2006

Hello Lennon len> Guys, tell me what is the difference between the “street” and that vegetable garden len> microcircuits that are used, say, in Pentagon 128? :v2_cool; Consumption.;

From Mark Antonov To All 11 September 2006

Hello Lennon len> Is the logic 100% repeatable? no len> Are there any subtleties? spinning tops were also different, 48e, several 128x (something can be found on the Conan website glean) len> How much does this affect the operation of programs? many domestic ones are buggy/not working correctly, the opposite is not true len> But as far as I remember now, it was said that programmers know this len> and therefore avoid this pitfall. programmers over the hill know and bypass. most of us don’t care - don’t care about p128 it works

From Yuliy Trunin To All 11 September 2006

Hello icebear ice> Consumption. Is the logic 100% repeatable? Are there any subtleties? :v2_blink; AND; They also say that the company 128 has brake memory banks. How much does this affect the work of programs? I'm still somewhere in literature I read that this exists but didn’t pay attention. But as far as I remember now, it was said that programmers know this and therefore avoid this pitfall. Am I wrong? :v2_blink:

From Robus To All 12 September 2006

Hello Lennon len> And yet, they say that the company 128 has brake banks len> memory. How much does this affect the operation of programs? Very strong!!! Even if the interrupt vector I is left in the range from 64 to 127 and at the same time write something to the disk, with information where the recording took place, we can say goodbye! Not many of us give a damn about this! For all the time Codinga has been on Speccy, I only did two works for Pentagon, the rest were done automatically I determine whether the Speccy is braking, and for one thing they are fixed under Turbo. For example, RST 7 did the same!

From Grand To All 12 September 2006

Hello Lennon len> And yet, they say that the company 128 has brake banks len> memory. Here is their list. For Spectrum 128+ and +2; FAST; 0, 2, 4,6; SLOW 1, 3, 5, 7. For Spectrum +2A, +2B and +3; FAST; 0, 1, 2, 3; SLOW 4, 5, 6, 7.
