This is a great explanation!
But I do have to say, you darn kids with your fancy newfangled PS/2 input.. in my days we had proper serial or DIN ports!
I saw a computer with a parallel port at work the other day.
No idea why it had it, it also had a couple blue USB3 ports. Also VGA and HDMI, and a bicolour PS/2. Damn weird mainboard.
Zoomer intern was wondering what it was and I got to tell him about parallel and serial and all that. Made me feel nostalgic. And old.
Maybe it was even a 25 pin delta serial? or an external scsi port? Sounds damn peculiar indeed.
No, it's been a while since I last saw a SCSI connector of any kind, and I don't think I've ever seen a 25 pin serial (my first PC did have the 15 pin game port, though, if I recall correctly); this one was a plain old parallel port, though. Even had a small drawing of a printer on top of it on the i/o shield.
I recently saw a picture of a SCSI connector when looking for PCIe - SATA cards.
Apparently most normal PCIe - SATA cards are very unreliable (somehow even worse than USB to SATA adapters), so I went on looking for the SCSI ones that have been reviewed as more reliable.
P.S. If anyone knows about a (non-RAID) PCIe - SATA card that I can rely upon as much as my motherboard SATA controller, then do tell.
