Nope, again, wildly different artifact colors can happen in any mode where NTSC burst is enabled. It's true that 640x200 is the only BIOS mode that doesn't have a "burst enabled" counterpart, but...

Pretty sure IBM would've been aware of it, and 100% sure that the PC's engineers were. Recall that the first IBM PCs were also available in "home computer" configurations, which pretty much meant a...

It's been a long while since I've done this, but IIRC the key is changing the CF's media descriptor to "fixed", since they're normally flagged as "removable" and Win7 won't install on those.

How...

Although they should really be called multi-sync, since they can do 15KHz as well as VGA.

I don't really get this newfangled fetish for keyboards with hardly any keys on them.

In my last job, I inadvertently made a young and impressionable coworker into a keyboard enthusiast. I was...

Having recently read this interesting history of PLATO... that system's terminals allowed you to "overstrike" character bitmaps on top of each other, more or less like you could do with a typewriter....

I want to say no, because very very few games were ever targeted *primarily* at MDA.

Examples do exist, e.g. https://archive.org/stream/PC-Mag-1984-01-24#page/n383/mode/2up. But if you read the...

Ha, interesting - the results from my attempt are the other way around, but keep in mind that I "cheated", since my 4K upload was just a 2x nearest-neighbor scale of the 1080p version.

The...

Will do. For now I can say that what I'm feeding to FFmpeg is rgb24, nearly always -c:v libx264rgb -crf 0 simply because it's both fast and guaranteed lossless, and I can spare the disk space.
It's...

Interesting... are we talking nearest-neighbor rescaling?
On the other hand, let's say I do that with a 1080p video (i.e. upload YUV @ 4320p), wouldn't youtube just create a 1080p version and *then*...

I gotta ask this, because it's driving me up the wall: some of you must've used RGB source materials for your youtube videos before, e.g. from captured or emulated PC video footage and whatnot....

That's suspiciously similar to what a "normal" CGA monitor does if you reduce the Horizontal Sync Position on the PC side (MC6845 register 02) to a ridiculously low value.
Deduction = something...

Although I don't have any interest in putting political stuff on my youtube channel personally, I'm in the same moral dilemma boat, since I'm *not* a fan of what they do on that front, and yet my...

Probably interested in a few of these. Got a photo of the unknown ISA8 graphics card? I don't think I see that one among the attachments.

Where in Israel are you? I may be able to do local...

See if FASM meets your license requirements. The assembler itself is a 32-bit executable, so as mentioned above it needs a 386 (and CWSDPMI), but it can generate 16-bit DOS code simply and easily...

For what it's worth, I've had success imaging the 2gb CF card from my 5160 under Windows, and getting PCem to boot from the image.
May not be relevant to your case, but others might find this...

Looks like one of those CGA clones that can be jumpered for monochrome output (http://www.uncreativelabs.de/th99/v/C-D/52640.htm), but only with a single level/intensity of green, so the result...

Well... what video card are you driving that monitor with?

The 5151 was intended for MDA/Hercules resolutions (720x350), but the screens in your photos look like something out of a CGA or similar...

Ah yes, the BASIC manual also makes it clear that "medium resolution" refers to the TV/Joystick option. More than 40 columns/320 pixels wouldn't have been very useful on a TV... 4 colors still ain't...

Nice!

I was considering Pillow for something very similar (generating the bitmap font previews found here), but I ended up being even lazier, and wrote my script using ImageMagick (and ffmpeg,...

A couple of questions I have about how text output works on the Model 2000. I don't own one so I can't answer them myself, but call it historical research.


In text mode, is 10x16-pixel...

Turns out that PCE is no slouch even with Teledisk images. I tried those HP-150 disk dumps as they were - wasn't expecting much, but MS-DOS with HP150.SYS loaded read the files just fine. :)

Some very early Model Ms support the XT protocol, and maybe some were even XT/AT-switchable.

However I think the BIOS *also* needs to have Extended Keyboard support to handle them. The Rev. 3 XT...

Ha, the 8x8 charset in this one is the Hebrew code page (862). Nice find.

Was this sourced here in Israel? I don't think I've *ever* seen a PC-1 around here. :)

86box uses a more accurate 808x CPU core (reenigne's XTCE) than PCem. It also does a surprisingly good job of running almost the entire 8088 MPH demo, so the proof is in the pudding.

For most...
