Hi everyone, I've found an easy solution to convert raw HDD images to VHD format. Microsoft's VHDTool has a converter function for this. Maybe that's useful to all of you who are 'upgrading' from 86Box/PCem or Qemu to VPC*. ;) Please just don't forget to rename the file extension to *.VHD. Best …

I forgot to mention.. There's an issue I totally have had overlooked. Early 80386 chips were market "16BIT S/W ONLY". They had issues executing 32-Bit software kind of. At least on their rated speed, underclocking may or may not helped. Intact samples got the "double sigma" marking instead. Anyway, …

Hm. I'm not entirely sure if you guys reading this thread have a real perception about the professional or commercial use of a multi-tasking OS in the 1980s. So please let me explain. I hope you don't mind. It's nothing personal. - I don't claim to be a true professional, either. But I knew people …

But judging by your response, I'm afraid you don't realize how much that had of an value to professional users and small offices. :sad: I do realize that very well. But at the same time I realize that running DOS apps wasn't viable as long-time solution. Do you? Did you ever work with Clipper or …

https://en.wikipedia.org/wiki/PC-MOS/386 "PC-MOS/386, a successor to PC-MOS, can run many MS-DOS programs on the host machine or a terminal connected to it." Yet another multitasker for DOS apps, right? No native 32-bit apps? That would be exactly the opposite to what I dreamed of. Not exactly. It …

Or let me put it this way: The official minimum requirements are never real. They're an understatement. If you buy hardware or software, you always have to upgrade it in one way or another. That's how capitalism works. Exploitation of man, by man. (That was a pr*paganda statement teached in frormer …

To be honest. I never did understand the 8086 models.. They shouldn't belong to the PS/2 line. :confused: Even for simple diskless stations, the 8086 didn't make sense to me. A slow 80286 or 386SX (if cheaply available to IBM via contract with intel) would have been much better, Wait, they did. IBM …

Now, let's imagine this alternative history... 1987 Instead of the elephantine 286 OS, a simple 386 OS is released. Basically, it's like DOS, but 32-bit. There may be also some "Pro" variant with multitasking, GUI, etc., but it's important that the basic variant is about as simple as DOS, and …

It is the 44pin PLCC near CD-ROM connector. +1 There's also diagnose.exe , which shows the DSP version. Or testsb16.exe , its older cousin. The diagnostic program NSSI also has a DSP detect feature, afaik, but maybe it's not as accurate as Creative's own utility. Edit: AmoRetro has hi-res scans of …

Hi there! 🙂 I'm often using WinImage on my old PCs. Alternatively, Disc Copy Fast on my XT in plain DOS.. In the past, in the 90s, it was QCopy 4.0 on my 286, too. WinImage 3 runs on Windows 3.1 and 286+.. https://www.youtube.com/watch?v=0zEVBO84afk https://www.youtube.com/watch?v=2HIk4YhBrGk …

Speaking of opto coupler speeds.. It does not need to be fancy. Way back in the past (19th century ?), incandescent lamps and selenium cells were used to build lightphones. So even a light bulb is fast enough to transmit sound, even if it merely covers the minimum bandwidth needed for human speech …
