Re: HTTP/Rest client for Windows 3.x (development)?

The API documentation for Win16 is actually extremely easy to find – it’s all contained in win31wh.hlp. The problem is that this API does not include any socket functionality, as the networking stuff was usually provided by third parties. The winsock API is mostly the same as it is today, though, …

Re: Latched EGA + Question about how dosbox does memory mapped I/O

Yes, but why would you care? The copying does not happen by going through AL. In fact, what goes into/out of AL does not matter at all. What matters is that the movs trigger reads and writes at the relevant addresses. One byte read copies one byte from each of the four planes into its latch, while …

You are doing 8 byte loads/stores so of course it would copy 8 bytes (in each plane, if the graphics registers are set up like intended). This amounts to 64 pixels.

Windows XP plain -> SP3 is not a problem. I’m not so sure about 98 -> 98 SE. This one, I personally would install from the 98SE installer. Put everything onto one disk. Splitting it up onto multiple disks just makes it messier. I have a Pentium 4 board with the normal two IDE and two additional SATA …

This is very surprising. Also I would not expect the behavior to have changed from 386 to at least Pentium 4.

the windows 3.x version has way better graphics than the DOS version, you can look at this video of the win 3.1 version https://www.youtube.com/watch?v=28IhouNUnyw Isn’t it the same graphics as in the DOS version, just shown at a higher resolution, so you can see more of the map? The tiles are even …

The question is just wrong. What you probably want is to put "C:" on the next line.

No wait, I can reproduce it, using edit.com, like you did. The other editor that I used earlier (IBM’s E) had no problem writing the file. Likely has something to do with SHARE.EXE emulation.

The problem is almost certainly the space in the path. The easiest way to circumvent this would probably be to use the short name (progra~1 or the like).

So it's basically the same way as with floppy disks? The read head must read and decode the entire track until it finds the sector to read/write (unless hard-sectored)? No, drives "know" where the sectors are located. If it’s not static, then at least they have a cache for that information so that …

I used the 6-key block on a PC keyboard with the left hand as the cursor cross + 2 keys for up/down. For looking, I used an analog joystick. And for rolling, I extended the left hand’s thumb and used the 0 key on the numeric block for rolling right and the right cursor key for rolling left.

Are you sure it doesn't use the set/reset mechanism instead of accessing all planes? The recommended way to set a single pixel (assuming write mode 0 / no data rotation / no other frills are enabled) is: Set the enable set/reset register to 0Fh Set the required color in the set/reset register Set …

I know Q Basic (not sure about GW Basic) is capable of some kind of 16 color mode, where the color of each pixel is specified by single PSet statement. I'm not sure how it does that. When PSet is used in 16 color mode, Does it switch beteween all 4 color planes and set the color of the pixel? If so …

It switches to max when it goes to protected mode. By the time games used protected mode (DOS extenders), they were definitely able to keep track of time independently of CPU cycles.
