Re: Using Atari ST(E) without floppy - can be good way

https://youtu.be/LivmcJQl51w That's early demo of faster startup and how state save and restoring works . What is not visible in video is: save goes by holding down left shift+Ctrl + pressing key 1-9, or 0. Will save complete RAM, screen parameters + couple other things. Restore is with holding down...

Re: Using Atari ST(E) without floppy - can be good way

Memory is not changed, but reset signal goes on peripheral controller chips and resets them too. What means that you can not read their original state then. And keypress detection is just one of possible problems with SW not using TOS functions. For instance reading exact values of MFP Timer's regis...

Using Atari ST(E) without floppy - can be good way

This is actually not that new and rare - some people do is over years already. Why floppy is still needed in 2018, for machines equipped with some Flash card mass storage: Playing games - many of it work only from floppy. Well, that changes and lot of games can now work from hard disk/Flash card, an...

Re: Determined to add internal IDE to my STFM

Fine. But then will need extra PSU for 3.5 inch drive - Atari's is not enough strong. 2.5 inch may work well if Atari PSU is on good condition. I used my 520 ST with diverse 2.5 inch drives in period 1992-2000 .

Re: PC mouse refresh rate

Yes, that's known problem with current (O)LED technology. And btw. same was present with early LCD displays. Was not called burning, but basically same thing - degradation after some thousands of hours usage. Progress seems to be not so fast in all areas .. Main reason why it can be better is simple...

Re: Determined to add internal IDE to my STFM

I'm sure you will solve placement of it in good way. Usual problem with IDE in old computers in last years is: what CF cards are good for. What disk or CF card, maybe some IDE/SD adapter you plan to use ? Lot of CF cards may have writing problems, what is caused by not really proper signal timings o...

Re: PC mouse refresh rate

You guys are going into wayyyy to much detail. Jerky mouse pointer on modern computers: Combination of 60hz & lack of desktop Vsync To fix: Get a 120hz monitor or higher Done :) I think that using better driver SW will cost 'little' less :D Why should I get 120 Hz monitor when I don't have anything...

Re: PC mouse refresh rate

Human visual perception has limited speed. It needs time to process incoming visual. That's mostly some kind of intellectual process. And needs much more effort and energy than optical part of view. And that's why 24 fps makes already good impression of movement. But new tendencies are to go on more...

Re: PC mouse refresh rate

"The most fundamental difference between CRT and LCD is that the latter (usually) doesn't redraw the complete image every frame. LCDs only update the difference. That's what sample-and-hold is about. Some LCDs have a strobed backlight (and some OLEDs have black frame insertion) which effectively doe...
