PAL encoder and Scorpion. — ZXNet «hardware.zx»

From lvd To All 13 February 2006

Hello, CHRV CHR> Yesterday I tried Scorpios with a preliminary version of ZX->VGA. Ass CHR> is the same as from a PAL encoder. Synchronization immediately dies, image CHR> goes somewhere to the side, the desynchronization is complete. CHR> On Kai, Turbo and Pentagon1024 everything is fine. CHR> So I won’t sell ZX->VGA to Scorpio people :). That's it, and after that some irresponsible individuals still begin to argue, that scorpio is the best comp! One of the worst... =) They put a shadow video on the wrong computer :))

From Konstantin Zhukov To All 13 February 2006

Hello, lvd There was a topic about improving the synchronization of Leningrad on 27512. Maybe try the same scheme in relation to Leningrad-3 (Scorpio)?

Hello, CHRV CHR> I already found the jamb, which I wrote about in the first post, I’m just lazy CHR> fix it, especially since someone knows how... Yesterday I tried Scorpios with a preliminary version of ZX->VGA. The ass is the same from PAL encoder. Synchronization immediately dies, the image goes somewhere to the side, complete desynchronization. Everything is fine on Kaya, Turbo and Pentagon1024. So I won’t sell ZX->VGA to Scorpio people :).

Yes, of course, but I’ll probably do it on PLM, but on ROM it’s bad because the needles can occur when the value on the Scorpio counters changes. But damn, you can’t do enough for every computer, it’s the guys who give it to them for repairs I’ll do it, and let the rest do the same :).

From Chunin Roman To All 14 February 2006

Hello Costa Cos> Finally name the best. From the point of view of the video signal standard, the best are original, KAY, ZXNEXT, Turbo2+ (at least from those that I tested).

Hello, CHRV CHR> I fucked myself with a subject all Sunday. CHR> There is a very strong suspicion that Scorpio did it wrong CHR> synchronization, and specifically burst-blanking is calculated incorrectly CHR> interval (i.e., roughly speaking, the beginning and end of the vertical CHR> synchronization)... CHR> There is a suspicion (the color is restored in separate lines) - business exclusively in line synchronization. The impulse, I guess, is direct transmitted from the encoder to the TV and then either incorrectly perceived encoder, or a TV, but there is a signal recognizing the presence of the actual color signal in each line - maybe it? This is just a guess. > By the way, the preliminary version of ZX_VGA also refuses to understand > scorpio (the image is doubled). > Vertical-interlaced? I also have dual problems with Radeon, if not throw away every second field (frame). Development is perceived as interlaced and every second frame is captured haphazardly.

From Pavel Dovgaluk To All 29 March 2006

Hello, CHRV CHR> Because of this, the top part of the screen usually creeps to the side on the monitor CHR> (first lines twenty/thirty)... Here I connected a yellow scorpion to a modern LCD TV. Once every 1-2 seconds the image “runs” cyclically in the vertical direction. Does this mean it has the wrong frame rate? Or maybe something else? PS I also connected other clones - most work fine :) They don’t work only Scorpio, Pentagon-48 and, it seems, Leningrad.
