Hello, you need to read from that memory location first in order to fill the latch registers. A zero in the bit mask register means that the associated bit of the latch registers will be written back to that memory location. If you got zero in the latches, then zero is what will be written.

1. Are there any other compatible modes that would be possible on all CGA, EGA or VGA adapters? I read references to a 90x60 mode, but not sure if that would be compatible. Compatible modes for all cards would be those defined by IBM, as the details about the resolution and character size are …

The weird thing is, is that this problem is already there after a fresh instalaltion, so is it "default" for this windows version? I can't remember this being this way back in 1999. Yes, it's like that for the whole 9x series, including ME. From what I could find, MS changed that behavior with IE6. …

-Dune2, Same as above, the Granddaddy of RTS but the game is so slow!! You can alter the game speed in the options, I always use "Very Fast". Maybe it's because I grew up with it, but I never found Dune II to be slow. Well, units do move half speed when off screen, so if you keep them on screen as …

Windows 3.x There's also an updated version for the Calculator.

Nokia 2610, actually two of them. One of them I've had since 2007 or so. I guess it shows that I'm not into phones. If I can call and occasionally text someone, it's enough for me.

That guy kind of reminds me of myself in many ways :D Used XP for 17 years before switching to 7 in early 2019. Used it for everything, but software support was dropping quickly, mainly the browsers, and I figured that 17 years was a good timespan already and it's time to move on. 7's quite ok …

No, you didn't need to have DOS installed in order to install Win95, in fact Win95 was the first windows (apart from NT) not to require a pre-installed DOS. It came with a startup disk in order to boot and then run setup from the CD, as booting from CD directly wasn't common at the time yet.

Hello, on my laptop there's a key (or better said, the key combination Fn + F7) that toggles scaling. Or you could look in the options of the graphics driver, there should also be an option as to how an image should be scaled. I don't think there's a DOSBox option for it, but you can look in its …

Were there actually any 4:3 LCD monitors in that size range? Back in the day I went directly from a 15" LCD to a 20" due to the lack of 4:3 monitors in between. Even those advertised as 4:3 were in fact 5:4 (native res 1280x1024). There might have been a few exceptions, though I guess they were …

"I could do that, but won't that mess up the time/date?" If you call the original handler at the original frequency, then no, otherwise yes. Let's say you let the timer run at twice the speed, then your int 8 handler has to call the original int 8 handler every second time that your handler is …

I just took a look at the timing.zip that you mentioned. The int 15h function 86h method is used in the code "intdelay.bas" in the "delays" subfolder, maybe that helps.

I don't know about QBasic, but the BIOS offers a function to wait a specific time (int 15h, function 86h, time to wait in microseconds has to be in cx:dx). Maybe you could implement that into QBasic somehow?

Generally it shouldn't be any problem. However you have to check for each board anyway as you need to set the jumpers accordingly (voltage, etc).

They were all slower on the P90. The overall times were like this: A: 2.087000 to 2.143000 B: 2.142000 C: 1.867000 D: 12.633000 (yes, that long)

Would a P90 be OK, too?

Hi, WordPad uses .wpc files to do the conversions. In XP the files "mswrd6.wpc" and "mswrd8.wpc" are located in the same folder as the wordpad.exe file itself, I suppose it should be similar in Win 2K. If you copy the mswrd6.wpc over as well then 2K's wordpad.exe should open Word 6 files in Win 7, …

Hi, in ME it's done via msconfig. Launch it and click on the "International" tab. There you can select the desired language settings for the DOS prompt, but you also need to delete the paths, leaving only the filenames displayed (i.e. instead of "C:\WINDOWS\COMMAND\country.sys" the field should only …
