VLB was dumped because it was pretty shit. It wasn’t going to survive past the 486 because it basically assumed, absent any other bridging logic, that it was connecting straight into the memory bus of a 486. You couldn’t drive more than a couple of cards because electrically the situation was a dog’s breakfast of a hack job and because the hack job was so bad if you put a hard drive controller on it you would be risking losing data and trashing your disk.

- chasil 2y agoIt is a great personal career risk to push such sentiments up into management that have harmful impacts on other partner companies and/or internal projects. Intel's corporate culture specifically failed to do this with the Ittanium, where the technical failings were ignored. I guess the industry is lucky that Intel Architecture Labs was permitted greater freedom.

- duskwuff 2y agoAre you thinking of the "GeekPort"? That wasn't connected directly to the CPU - it was a bunch of digital (and a couple of analog) IOs, kind of like a cross between the PC parallel port and game port. The Amiga had a "CPU-port", but that was a much older and slower system.
