Bought DR-DOS 5.0 for my 286 build. With manual. I am tired of retrogaming to be honest. Every review sets as a goal retrogaming and nothing more. There is plenty of abandoned software - different OSes, different utilities, memory managers, programming tools, editors. Why should I spend tons of …

Has anyone scanned the manual yet? Do you want to know something particular or just have the full set? :) Like mostly I am interested in it as being 8514/A compatible, so having the datasheet is much more important to me. Jumpers are described, I know the amount of memory and going to try if it …

Thank you for your help, guys, I will start digging again. It's a wild hunt, I cannot reach a few people known to had at least Targa 16. I suppose they were compatible.

Yes, GBS-8200 looks like 15kHz VGA to 31kHz VGA converter only requiring some intermediate DAC (like PAL based solution or even the simplest resistor based thing without brown color hack). But this one is much more sophisticated with pretty solid upscaler, at least from description. :) There were so …

So maybe MCE2HDMI consists *only* of the RGBtoHDMI implementation? (i.e. everything is done by RGBtoHDMI and there is nothing else in MCE2HDMI) Is this also how you've understood it? Never dug so deeply :) I just needed some solution allowing me to use MDA adaptor for debugging or EGA for one of my …

Is there actually a manual or some documentation somewhere? It's an implementation of another project - RGBtoHDMI - I missed that link in the description initially. Here is wiki - https://github.com/hoglet67/RGBtoHDMI/wiki And here is explanation of the buttons functions - https://github.com/ …

It’s a Targa RGBS video capture video card combo. For capture It’s compatible with Sony video scanners , Kodak Flashsync ccd4000 cameras and could capture Amiga video. Output it works on a multitude of 15khz Magnavox Amiga monitors. I don’t think it has a video bios so good luck finding software/ …

Lol. "Edsun's Windows driver development program cost $1.5 million and never delivered PostScript font anti-aliasing support". They spent 1.5 mln back in the days on writing Windows 3.1 drivers and failed?

That's interesting. It seems like EGA lived not a long life and never got its full potential. I'm trying to make my new build like it's 1990 and want to have powerful 286. 12MHz is enough though there were even 16-20MHz options. And watching plenty of ads of year 1990 I see there were even XT I …

I don't understand the point in not using vintage computer parts. That is just hoarding. There is a big difference.

Well, I'd be surprised if I got the newest BIOS and drivers on the controller out of the box, but the sticker saying it has ATAPI support is promising. If the a controller doesn't support at least LBA28, it's just sort of a curiosity, and not worthy of a real build, am I right? I feel like I need …
