Thank you for this file. I briefly had a look at the files inside and when tested the DOS mouse driver, it was version 7.30. The file timestamps have all 7.40 so I thought it would be version 7.40, so I will have to install the Windows driver too to see what it shows. What is the origin of this …

I know that quite much drivers can be found on different abandonware and driver websites, but I would like to find complete disk images. Usually the Logitech Mouseware …

Just tested it and seems like Alt+Pause works when I press the key combination in the DOSBox window. But when pressing Alt+Pause in the debugger window, it doesn't seem to work. Is there some way to redefine the pause key combination in DOSBox debugger? When pressing Alt+Pause in the DOSBox window, …

In DOSBox debugger, when I start a program with it and press the F5 key, the program will start to execute normally. Is there any way to pause execution of program in middle of something, so I could then easier check what is currently going on in the code?

Thanks. It seems like you are correct. I'm not familiar with resistor networks at all, I have just been using regular color coded resistors when I have made something. I just wonder what the "A" and "G" letters mean there.

The results are the following when running on virtual machines: DOSBox: 00110110 Virtual PC: 10110100 VirtualBox: 00110100 Bits 1-3 are 011 for DOSBox. …

I'm not sure if I have understood things correctly. If I want to get the mode for counter 0 and I have set the bits for the read back command, this just seems to return some random value when then reading from 40h. Own example code: function readpitmode:Word; assembler; asm mov al, 11000010b out 43h …

One addition to the initial question. When running this is a virtual machine, e.g. a 10 second delay will be 10 seconds. But running the same on real hardware, will only delay for 5 seconds. How do I fix it?

In Turbo Pascal there is the divide error bug. On website are ways to fix it. But there is said the ticks 1193180 per second. When I tested this on some computers, a 10 second delay using the functions below gave only a 5 second delay. On other website (http://www.delphigroups.info/2/d2/16758.html) …
