[..] In the past, I used to use GMouse, which was the Genius Mouse driver. But this was on a 286 system were I didn't load smartdrive, so my free memory was a bit below 600KB (~560-580KB ?) which most programs could still work with. These days however, things might be different. Stuff like MTCP and …

I love this thread. ^^ Fun fact: A 286 (10 or 12MHz) was the original CPU in the Multimedia PC specs (MPC v1.0) before it got revised to a 386SX (16MHz). See https://www.vogons.org/viewtopic.php?p=506399#p506399 Also, Video for Windows v1.0 also runs on a 286 still, v.1.1 requires 386 and higher. A …

I've got the feeling that VGA compatibility since a while is nolonger important beyond getting through the Windows installation. But even for that, and Linux, VBE 3 is all it needs. Makes me wonder why and howlong they still bother to include a full CRTC in silicon. However, If BIOS goes away in …

Yeah, 7.x needs 386 or higher to function. I can sort of confirm that. Firt saw this issue in the 90s with one my father's boot disks. He had a 386DX40 with Win95 RTM, while I had a 286 with DOS 6.2. When I booted his DOS 7.0 diskette, a message appeared, saying, that it required a 386 or better …

I think the same. CuteMouse is surely nice to have, but some older programs may prefer, say, MS-Mouse 6.24BZ (Win 2.x) or MS-Mouse 9.0. The latter is a memory hog but solved latency issues and jerky mouse movement. It also added features, like graphical mouse cursors and such. In the past, I used to …

Good luck! :) I seriously hope that you can find one. The early Pentium systems were high-end at the time and of higher production quality maybe. Personally, I think its getting harder and harder to find working components from that era. We're likely reaching the point at which all vintage hardware …

Is there a way to load DOS games into high memory? Yes, if you mean the range of 640KB to 1MB (aka adapter space, adapter's segment, Upper Memory Area/UMA). Problem is, the term for that region varried. Both in time and space (country). Originally, in English countries, that space was called "high …

Hi, I don't know for sure. Maybe archive.org will still be there. Maybe CDs and pen drives and future media will survive in time capsules. Or as bookware inside of books that are stored in libraries.

As "idspispopd" pointed out for "DOS related" drawing of primitives... it's bus & memory speed that counts - "filling 2D polygons" was done by the cpu(excluding specialized dos-executables which took advantage of some "obscure" hardware). That's right, DOS games usually don't use GDI-like functions …

^ Do that. Don't connect multiple outputs directly to each other. For line-level outs, it's... probably... okay... most of the time... since the outputs normally have a 100R resistor or such in series with the output, to protect it from shorts, but if you have card A driving a full positive signal …

I think the same. Also, you can check your serial/parallel ports easily by using, say, CheckIt! v3 and CheckIt! v4. With and without a loop adapter. Without anything connected, it will write to/read from the chips internally and display the results on screen.

Good CF cards can only handle a max of 1,000,000 cycles but typically start to fail around 500k. As derSammler and douglar mentioned, you need to limit how often windows is writing to them or else the typical 3 year life span (for a camera as example) will be cut super short. I don't disagree, but …
