You can safely assume its marketing wank, PC Mag 6 Dec 1994 description sounds like some kind of deeper fifo to hide rasterization delays from host (outputting framebuffer to screen blocks main host from writing to video memory). You would have to find actual alleged patent application to know more. …

Its not possible due to signal integrity issues surrounding soldering a spiderweb of wires in the air. On the other hand its totally possible to build VLB card with PCI bridge, or CPU interposer with PCI bridge :o) Some basics in reverse order (from difficult down to bed reading material), you …

I had to post a screen shot of the section cause the pdf won't let you copy and paste. Yes, this is not a feature of the CPU. Read second page carefully, it describes external microcontroller monitoring temperature and trying to tame it by halting cpu temporarily. This is a rough idea of a device …

its a socket 370? From what I remember about those cpus they had protection systems and throttling so if it overheats it slows down then shuts down. nope they dont, that came much later in Pentium 4 I'm still worried that I somehow damaged it when booting the system without a heatsink mounted. I …

I first played Half Life from start to end with a Pentium 133 32MB RAM Nvidia Riva TNT Sound Blaster 16, and it was totally playable. totally playable probably meant 15fps at the time, just like I managed both Doom 1 and 2 on 386DX40 at ~10fps and it seemed 'fine' _until_ discovering gaming cafes …

Thats the analog part (558), afair speed sensitivity was due to stupid 16 bit nop busy loops in game code breaking on faster cpus.

you cant just multiply 4 bits by ISA bus frequency and assume that to be the max >For theoretical max it should come down to max port polling rate of the four button pins. you need to waste cycles/bits on synchronization
