Hm. Hard to say. All of them, I guess. 🤷‍♂️ I'd like to keep some PCs in the state they existed back then, which isn't exactly period-correct. Many people in the 80s/90s upgraded their beloved machines to something that wasn't considered standard. And I haven't the heart undoing such modifications, …

What's wrong with format 10 20 ? All the others look like a way to justify 100K a year salary. :) It's too direct, too simple. Too reasonable. ;) Not much unlike a basic "Hello World" written in Pascal or K&R C. Once you're into programming for a while, the primal instinct of a programmer takes …

Edit: Don't forget about a dedicated 2D graphics core for good GDI performance. Geforce 6 and up do use a 3D core only, afaik. Geforce FX was the last one with a dedicated 2D core. However, the FX wasn't exactly.. Good. It could render Vista's Aero Glass, however. NV40 was developed before Windows …

Geforce 6/7 were also used in some chipsets as on-board VGA. nForce chipsets, I think. My father had an AMD Athlon system with such an annoying on-board VGA. It couldn't assist Flash acceleration on XP with Flash 10.2 and later (that required a Geforce 8/9 minimum). So we installed a proper graphics …

Internally a x87 coprocessor uses 80 bit wide registers but hardly anyone really needs such a precision. 80 Bits weren't that bad, actually. Some calulactors used even higher accuracy or so I heard. The creator(s) of the x87 FPU said that the FPU was most useful for practical users, not math fans. …

Beware, there are several revisions of IEEE-754. The original is from 1985, but the International version is from 1989 (IEEE 754-1989)! Which came out in the 80486 days pretty much. Older 8087 and 80287 and 80387 FPUs can't comply with this release, maybe. thanks, but do you know where 1985 version …

[EDIT] Wow, ran 'IEEETEST' in 86box and honestly I did not expect 14303 results to fail. So, even in 2023 what is used to emulate 387 FPU as code there is very inaccurate compared to a real hardware. This isn't exactly a solution perhaps, but Franke 387 was a good x87 emulator. http://icfs.de/ …

That's really cool, but thinking about it I'm not surprised. Despite popular believe, parallel and serial ports are neither primitive nor obsolute. Rate the contrary.

Afaik, on a real CGA card running in graphics mode, the text font inside of the PC BIOS is used. That's because the CGA text font stored in the EPROM on the CGA card is not accessible via PC/CPU. So the PC BIOS must use its own "duplicate" of a CGA font (which isn't necessarily the same as the one …
