From Konstantin Sviridov To All 7 October 2005

Hello d_wanderer Made a small revision of the list ["http://zx.pk.ru/showpost.php?p=3088&postcount=1"] on the first page of the topic. Arranged the models alphabetically. In addition, I updated the list and corrected him: - similar to . By the way, I really want to look at high-quality photos (acidrain promised, so we're waiting). - now, thanks to jtn, there is a diagram, I’ll study it at my leisure and tell you about it more details. added the circuit (thanks jtn). It turns out that such models (in small logic) there were two: with one and with two fields of RAM. scheme with one field RU5 is very close to (only without a disk drive controller) and, rather, In total, I had the same problems in tincture and operation. Perhaps that's why this version not as common as other Deltas. has been moved to the main list (thanks again to RW6HRM). The only thing that remains unknown about this model is the circuit board periphery>. As I said earlier, this computer is the most sophisticated in terms of connecting to it everything that is possible from the 580 kit. Coming figure out to what extent this was supported by software (ROM from this models are available as a .WAV file for tape). - surprisingly turned out not to be "Leningrad", but almost complete analogue of (company ). Unfortunately the scheme, or whator descriptions for neither one nor the other have not yet been found. About the manufacturers of its BMK (or PLM) are also unknown, there is not even its marking or names. Thank you very much for the photos provided, d_wanderer! If it is possible to make a couple more in higher resolution (general view of the board and body). - I would like to thank Ivan Makarov (Mack) for providing diagrams of this machine, developed by him even before joining Peters Plus. By the way, CHRV seems to have a board from it. The machine (video controller part) has been developed based on Zonovsky . Added to the list of little-known models, which I found on my at my dacha dear Avatar ["http://zx.pk.ru/showpost.php?p=18337&postcount=332"]. The summer season is approaching end, but we still don't lose hope of getting a photo this year :wink: . WBR, Conan aka Konstantin Sviridov

Hello, All I was in a hurry with the name: I pulled it out of my address book for 1998. But with The computer name was listed as in the attached description, but the author, of course, knows better. Thanks for noticing! The list has been corrected. P.S. Can you tell us in more detail about the upgrade to Peters-256? WBR, Conan aka Konstantin Sviridov

From Andrey Vorontsov To All 8 October 2005

Hello Conan 2Conan: together with the VAV file of the Orelevsky ROM on the disk that I sent you, there is also a reworked TZX, which is quite possible to convert to BIN (one of respected forum members mentioned that he is capable of such acrobatic performances :))) WBR, rw6hrm aka Andrey Vorontsov

Hello d_wanderer rw6> along with the VAV file of the Orelevsky ROM on the disk that I sent you, there is rw6> and a reworked TZX, which can be completely converted to BIN Yes, there is such a file with firmware for (attached). I tried to download and saved it as a block of codes, but the beginning turned out to be cut off. Perhaps who will do better? d_w> This is a photo of the board in relatively high resolution. Thanks for the photos, the quality is what we need! Find more information on for manufacturers of PLM (BMK) for them, maybe Ivan Mak (Archenko) can tell me what? d_w> In addition, I have a branded Spectrum 48 series AR306309 issue 2 82nd d_w> year of manufacture. True, there is no keyboard. If necessary, I can take a photo. A very interesting issue, the ZX Spectrum series were produced in Portugal (for Argentina and Italy) including with a non-standard , and AR marking has hitherto only been found in Sinclair QL numbers assembled by AB Electronics. Moreover, the number was printed on a sticker (sticker). If possible It will be very interesting to take photographs (and from the bottom too). Also a close-up photo of the board will be useful (so that the names and dates are visible microcircuits).

From Konstantin Sviridov To All 10 October 2005

Hello d_wanderer Thanks Dmitry! Very, very interesting information. Generally AR marking very rare, now we have to figure out (make sure) whether there was a numbering end-to-end The fact is that by the beginning of 1983 AB Electronix (without Timex and Thorn EMI) ZX Spectrum physically could not release 300 thousand. Yes, and cars with these numbers are very rare (models released by Samsung in a smaller number (rel. 300 thousand) are found on ). Moreover, in the numbers of series 001 (basic numbering) there is a gap around 300 thousand. If there are models with these (001) numbers, then 100% numbering is continuous. This is very interesting and means good coordination of different manufacturers at the initial stage (later it was worse). By the way, this (AR) model has an interesting feature. The fact is that produced Timex ZX Spectrum had a hole in the bottom of the case only for Issue1 boards. B Later, the holes were removed (although Issue 2 still had standoffs on the board). The reason was that too many "craftsmen" stuck screwdrivers in there and broke warranty cars. And it turns out that AB Electronics also had cars of the second series with hole in the bottom. As for the Sinclair QL, I’m almost sure that the numbers on your cars start with (less likely with ). By the number after the letter you can determine the board version (unlike ZX Spectrum). If you don't mind, drop itQL numbers to my e-mail or PM because the topic is still on domestic models. Thank you very much again! WBR, Conan aka Konstantin Sviridov
