Re: Window refresh problems under Geneva/Neodesk

I'm already noticing that even with debugging the redraw issues, the performance eaten by attempting to maintain the screen queue is enough to make the modem miss incoming data. This is even in 25mhz on a TT030. I will probably have to go back to my original mode of literally just painting over the...

Re: Window refresh problems under Geneva/Neodesk

Assuming I were to peel away the AES bits and just make this a TOS application, what's the correct method to initialize the display, and finally to hand it back to GEM? On modern TOS versions/alternatives, you can’t really use TOS plus VDI only (or direct screen writes), without telling the AES &qu...

Re: Window refresh problems under Geneva/Neodesk

[…] Using this (and the device specific VDI raster copy functions), you can draw into your own offscreen buffer (device specific format) and blit the result to the screen. Beware that this covers all the basic Atari screen modes, but will not work on e.g. graphics cards of PC offspring that use lin...

Re: Window refresh problems under Geneva/Neodesk

Actually, I have an idea... Instead of using VDI calls to draw the window, I can have the AES do the work by creating user defined objects for my drawn primitives (line, dot, alpha, block erase, paint)...this would allow the AES to maintain the window in its rectangle list, and redraws would just w...

I have not seen your code, so not sure what you have done.

Re: Window refresh problems under Geneva/Neodesk

However, when testing in windowed mode, things go strange: The application re-maps the palette, because PLATO can support color. I have a function which iterates through the entire palette, and re-maps it whole cloth. However, I only see the background color change, and the window remains blank. If...

Re: New visitor? Your first three posts need to be approved

I have now got interested in the Atari scene again somehow. Anyway, had a Nintendo 8-bit in the good old days and sold that for an Atari 1040STfm around 1989-90 I think. Used to do a lot of graphics, fonts and such. Had a site a loooong time running, which featured many of those fonts. My first/old...

With 4 MB RAM it should be sufficient to run Windows 3.0 in Real Mode. It won’t be fast, of course … the used NEC V30 is a slightly improved 8086, about 10-20% faster than the original.

Re: Atari TT030 and system V

Though one would think part of that might be due to memory swapping? Back when I first started using Linux, I think I had 32mb of RAM and it swapped a lot once I started up a few applications, which of course slows everything to a crawl. It is not the swapping. The ~5 MIPS of a TT isn’t a huge amou...

Easy! You just need to know how write device drivers for ASV. And a USB stack for ASV. Talking to the Lightning itself is easy, as there’s free code to do so.

The IDE port on the MonSTer won’t do DMA at all (like in the Falcon and so on), so in that understanding, it is bypassed, yes.

Yes, VDI. sorry, :) As for my last sentence, I am talking about the fact that only NVDI seems to have a facility to e.g. blit from an off-screen bitmap, scaling downward as needed. This is ultimately a show stopper for scaling cleanly to a window with its dials, in lower resolutions. -Thom Ah, yes,...

Re: Planning a PLATOTerm port for the Atari ST, some questions.

The terminal is NOT a VT-100 or similar text terminal. Think of it something closer to a Tektronix 4014, where you have no scrolling and everything is drawn on a single screen, with the ability to clear the screen, or parts of the screen. As it is, right now, I am having to scale the original PLATO...
