Re: SVGA/VESA programming

Hi everyone! And sorry for intrusion, also. I'm a bit late to the party, too. 😅 I'm not going to convolute this thread, I just wanted to say that 640x400 256c is a good starter indeed. Games like the Höhlenwelt Saga used it, too. And a few more games from the East or Korea, I think. Mode 100h works …

Re: Voyager probes 40th anniversary

That was a great read. Has NASA had any more updates on the data anomalies of Voyager 1? From what I've been reading the probe is still sending back science data and it appears that the signal strength hasn't been effected. I'm sorry. 😔 I'm not sure to be honest, from what I read so far, the people …

5) Generic 9600 baud modem (to play with ATI commands) configured as COM2 Cool, I also kept some modems. The internal types do have a fast FiFo directly built-in, so there's no trouble with using outdated/buggy 8250 or 16450 UART FiFos. Personally, I've always planned to connect two PCs via …

Re: Tseng ET4000-W32 compatiblity

I've just learned more about the differences. There also was an older Tseng ET4000C, even! 😃 However, demos like Copper that required an ET4000 were meant not only for the ET4000AX, but expected a specific revision of it (TC6058AF).. Here's an old thread in which h-a-l-9000 mentioned it (please …

Vogons stopped being a "only dosbox" forum many years ago, and became a lounge for retro electronics lovers... I think the irony is that this attracts both experts/enthusiasts from the physical hardware scene and the emulation scene. If done right, there's a potential of each group to benefit from …

Re: Converting a PC Booter Game to Cassette Tape

Posted on 2022-06-19, 21:01

Wow, awesome, I have always been fascinated by the (almost useless) cassette port on my 5150. Guess I'd better go dig out the tape player and get it connected up... Me, too. But for other reasons. Cassette I/O wasn't just used for datasettes, but also for communications. Things like RTTY, Packet …

Re: Windows 98SE on a PCI-E only AM4 motherboard

^VIA6212 is an USB 2.0 host controller chip. It was often installed on PCI cards with USB ports. Physically, PCI-E (PCI express) and old PCI are different, but not software-wise. Both look the same to software (they share the same basic functions, at least). So it's possible to make PCI-E cards with …

Re: Yet another 286 build.

^Thank you. ^^ Personally, I've seen a photo of an interposer card in an magazine from the 1980s. CHIP magazine, I think, so circa 1985 to 1989.. The card roughly was the size of two lighters and had a crystal oscillator and an 287 in a socket. Unfortunately, I have absolutely no idea were the issue …

Re: Can't Create Partitions after DOS install

Posted on 2022-06-19, 14:04

in DOS
Hm, that's weird. 🤔 The advices from our fellow Vogons users are fine. Traditionally, there's the 504MB limit of old BIOSes and the 8GB limit (Large model, E-CHS). And for DOS: - 32MB (FAT12 or old FAT16, DOS 3.x), - 2GB (max. partition size without patching; DOS 5/6) - 8GB maximum HDD capacity (DOS …

Re: Windows 10/11 support for 24-bit colour

Posted on 2022-06-19, 10:01

in Milliways
The last time i've seen a 24-bit color desktop mode was in the VLB days, so... I second that. Personally, I've seen it in the Windows 98SE days last time, I think. But with Windows 95 era hardware. A Pentium 75 with integrated 2D graphics chip, I think. Something like Cirrus or S3, maybe. Which was …

Re: Windows Workgroups 3.11 - USB

in Windows
Hi there! May I ask what you want to do with them? If it's just about USB mass storage support, you can try drivers like usbaspi.sys, usb_cd.sys, di1000dd.sys etc.. 🙂 USB storage drivers that work in DOS 6.22?

J1 - In position 1-2 FPU uses the main oscillator. In position 2-3 FPU uses the oscillator next to it. If position 2-3 is selected and that oscillator is not present - no FPU. Oscillator's frequency cannot be higher than the main (first) oscillator. J2 - No visible change in perf or other …
