Difficult video extension for Spec

Hello, Vladimir Kladov Vladimir Kladov> I, like many (I'm sure), are happy with even 2-color sprites). I used to think so too. :) I can only advise you to re-read my topic. And about 4x4 too. Vladimir Kladov> The success of the Spectrum is not in how the memory is organized, but in the fact that there was little of it in it, and therefore it was the cheapest. Cheapness explains only the initial success (and other computers had memory comparable quantity, and prices gradually leveled off). But he can't explain the fact that Speck (the platform, not the company) remained “afloat” for so long with such competitors. The reason here is the huge amount of software, of which there was a lot, because thanks to that very simple access, everyone could code on Spec. A But on other platforms you had to study the hardware thoroughly beforehand. Programming games on Spec placed more demands on the designer than to the encoder. That’s why there are so many lame toys on there too.

Hello Costa I, like many (I'm sure), am satisfied with even 2-color sprites). Me (as and the majority, and not only players, but also programmers) are not happy with clashing due to the fact that the attribute is attached to an 8x8 square, and a motionless one. And won’t even be very comfortable (yes, ugh, not at all comfortable) with the transition to a 4x4 binding or even 2x2. It is inconvenient to make normal graphics under such restrictions, or then remains mono or clashing. And if the connection is not to a familiar place, but to sprite, and the sprite will be transparent against the background of a regular image, which you can carefully prepare it so that you don’t feel much of this drawback, it is generally a pleasure. And then it doesn’t matter, hardware and an image is built on the fly or sprites are built in video memory using video chip commands are transferred wherever necessary according to commands from the main processor. Just in the second In this case, you need a large video memory to immediately build an image at least 16-color / per dot, which is what the v9990 has, judging by the description. Remaining wait until they give us a hint about how it will be organized interaction with v9990. At least this point is interesting: how will it be carried out? recording into video memory: natively through its ports or something. There's something there it’s somehow long and difficult, it seems to me that he will have more bars, at least To the extent possible, transfer to video memory could be simulated by direct recording tosome kind of memory. It would be like dma. Well, there is also otir, of course. It doesn’t matter how, tell me how. We want to know. The success of the Spectrum is not in how memory is organized, but in the fact that there was little of it in him, and therefore he was the cheapest. A Spectrum with a memory meter is no longer Spectrum. Nowadays 512K video memory is cheap (and probably simpler and often If you don’t have the necessary memory, it won’t be more expensive to find a larger one, and use at 20, 10, 5%). And then it was - wow. And in our union, the success of a spec was also determined by the fact that it was simple, and its it was easy to "copy". Just look at the MSX specification - how much is there devices, ports, memory, you'll get away with it. That's why it was like that I only recently found out about MSX (supposedly popular in the CIS in those years - nonsense!). His It simply wasn’t on our market, it didn’t exist. And his graphics are on the order is steeper than that of the spec, if it were available, I would of course make it unambiguous choice, even if it were 10 times more expensive.
