You can try something like "badblocks -s -v -w /dev/hda" - it overwrites the entire disk with various patterns, several times, which may force relocation of the bad sectors. But don't expect miracles...

It wasn't weirder: CGA - 640/200 = 3.2 MDA - 720/350 = 2.057 EGA - 640/350 = 1.829 actually, it was a step closer to the square pixel perfection of 1.333 Well, not quite. Using your math: CGA - 320/200 = 1.6 Super EGA - 640/400 = 1.6 So compared to CGA it's a step in the wrong direction in terms of …

Still, I'm curious to know how IBM(?) settled on 350 lines 350 scanlines was already used earlier, in MDA. I think the general idea was to create the replacement for both MDA and CGA, therefore 350 lines, color, and graphics. and ~22KHz scan for EGA MDA monitor has long persistence phosphor, so 50 …

It's weird to associate CANYON.MID with Windows 95 - it was already there in Windows 3.1, perhaps even in 3.0 with Multimedia Extensions? 😜 And it's definitely much older than that retarded paperclip 😜

Most popular were Tridents, as they were cheap. Indeed, they aren't great, nevertheless I consider them the perfect match for a 286 - totally period-correct, and very good CGA/Hercules compatibility. The most powerful would be ATI Mach64 with 4 MB of RAM, or some TIGA graphics coprocessors - but to …

Should I open the inner section? Only if you can do it in a dust-free chamber. Also, keep in mind that it's a stepper drive - and such drives in general don't park their heads automatically at power-off. So, if you get it to work, first thing to do would be transfer some head parking software onto …

Hi, could you identify this logo? It's on a generic-looking hercules card. No FCC, nothing on the back. Thanks.

I second what @davidrg said - no PC should be without LAN! Back in the era, there were two obvious differences between real computers and toys: HDD and LAN. The former had both, or it was easily added. And with both HDD and LAN, the need for floppies is minimal.
