@foone oh god I have a vision of a 3+ slot parallel card with a single port, enough to make Nvidia blush. @ArtifexUmbra @foone "you're going to want to liquid cool this port if you plan on running it for more than 30 minutes at a time" @foone 8 differential pairs per colour, except doubled up because you send two interlaced lines at once. @foone "Just one more prong, bro. Please, bro. C'mon, just one more. Just one more prong. PLEASE, BRO." @foone Don’t you mean a … parallel universe? (Dad joke, letting itself out the room. I’ll be here all week) @foone drew like a dark and fucked up version of a parallel port haha. just a glimpse into my dark reality. a full stare into my twisted perspective would make most simply go insane lmao @foone For anyone wondering (like I was a while ago) why all the cool parallel interfaces went away and everything is serial now: Apparently the answer is crosstalk. 😔 The signals on the parallel wires interfere with each other at higher speeds and longer lengths, so it's faster and more practical to just send info serially. @indigoparadox @foone That begs the question though: Why not switch to optical signaling?
The crosstalk issue is eliminated and the usable frequencies are *significantly* higher than those allowed by copper. @indigoparadox @foone Well, the other main reason is practicability: a USB connector is simply so much easier to handle (and cheaper to make) than a connector the width of your phablet. @indigoparadox @foone Also it gets really hard to keep the signals synchronized at high data rates and with long cables. @indigoparadox @foone That, and matching the lengths (as required at high speeds) of many wires is no fun. @foone while the physical connector is standardised in the german DIN standards system, the electrical properties of the pin assignments are not @foone I worked for the company that made these in the 90s. and they got bigger than that. |
