Re: 8086 clones with more than 1MiB of addressable RAM ?

in Milliways
Hello reenigne, thank you very much for your reply! And your explanation, of course. I did not know such tricks existed. Seems like the 808x still holds a few surprises for us.. :) As for the KP1810BM86M, I do not really know anything about it, either (hence the thread). Perhaps that soviet chip …

8086 clones with more than 1MiB of addressable RAM ?

in Milliways
Good morning, It is well know that the intel 8086 series can only address 1MiB of RAM, due to the limitation of 20 external address lines. But what about clones ? According to an entry at cpu-collection.de, some flavors of the KP1810BM86M can address up to 4MiB of RAM, due to 22 address lines. There …

Re: 3DO Blaster usage

Hi, only know the 3DO cards by name, never used one before. However, I have seen a youtube video about it quite some time ago. :) Interestingly, there is a 3DO software shown that runs on Windows 3.1.. If the PC is running Win9x, maybe that is the issue ? https://www.youtube.com/watch?v=l2CzI3qoci8 …

RE:birth sound hardware

in Milliways
Hello everyone, While browsing the web, I just found something interesting and thought myself it would be nice to share it with you, :) It is a blog entry / article about a motherboard for multiple tone generators from popular platforms, such as PC, PC-98 and C64. It is from 2015 so it is not new, …

Western Digital WD90C33 backwards compatibility ?

in Marvin \ Video
Hello and good morning, I have just seen a WD30C33-based graphics card on eBay and I am quite surprised now. Previously, I had no idea that these existed at all. Not only I thought that the 90C31 was the last one in the series, but I also had no clue that Paradise/WD ever made VLB cards (I knew of …

Re: Starting PC with DOSBOX instead of Windows 7

in PC Emulation
That is a good idea and certainly works for OP RabidClarkian. Unfortunately, it is not certain if that works for his father, as well. Parents can be, eh, very stubborn sometimes. Haha. :sweatdrop: They often insist in having things working the way they want or how they used to. If all goes wrong, a …

Re: Starting PC with DOSBOX instead of Windows 7

in PC Emulation
Hello, here are some more ideas: You can also run Win98 or FreeDOS from an SD* or CF card, if the computer has got a card reader installed. The BIOS of a PC from year 2000 onwards should handle it like an USB hard drive and then will provide int13h support for it. Problem is the installation, though …

Re: Pixel art / paint software for dos/win 3.11

Helloooooo I've been doing a lot of pixel art for my projects using a version of paint shop pro on my 9x rig. Issue I'm having is that I'm making these for programs running in mode 13h (VGA 320x200 @256 color) which is not square, which is resulting in minor aggravation due to the change in aspect. …

Re: DOS, how to set up from floppy?

These are interesting thoughts, I must say.. Windows 9x has it's own, seamless mouse driver which can be used in windowed DOS sessions. I haven't checked if CuteMouse gets in the way with that, but it could be possible that Windows uses the mouse driver that was in use first (CuteMouse, in that case …

Re: Media Vision Pro Audio Studio 16 strange behavior

in Marvin \ Sound
I agree with badmojo. The fast sound effect is said to often occur if the -5v line is missing. Also, in case you'r wondering, the default settings for PAS16's DAC are : Port 388h IRQ 10 DMA 3 Thunderboard is at Port 220h, IRQ 5*, DMA 1 FM is mainly at 388/389h (SB2.x had OPL2 also at 228h/229h) ( …

Re: DOS, how to set up from floppy?

I have an idea but I have no idea how to do it. Now I have win98SE on HDD and DOS6.22 of floppy (on USB in gotek) and my question is, how to make DOS to see HDD and CD drive? It's been a while since I did such things, so I can't give any advice how to add DOS subsequently. It's important, however, …
