DB9 is still used on for MIDI on electronic instruments, though some manufacturers are moving to doing it with a TRS 3.5mm plug since it only uses 3 pins.

I had a mouse that plugged into the serial port, but my first computer was a Commodore 64.

"do you know what ps/2 ports are?"

"holy cow, PlayStation 2? you must be AT LEAST 25!"

What kind of connector is this? I remember seeing them on 1970s audio equipment, maybe for mic in?

[–] BradleyUffner@lemmy.world 3 points 1 day ago (1 children)

It's an AT/ XT keyboard connector.

And back then if we did have a mouse, it was square, and used a 9pin serial port

[–] whoisearth@lemmy.ca 11 points 2 days ago (1 children)

This reminds me when a mouse was an option not a requirement

My keyboard still uses a PS/2 port via adapter. 1986 Model M, still clicky.

My first PC was a Timex Sinclair 1000 and I wrote a text-based choose your own adventure game in basic for it and saved the program on audio cassette.

I raise

edit, actually, it might have been on the back...it's been forever since I touched one

[–] TheRealShadeSlimmy@lemmy.world 41 points 3 days ago (7 children)

I’ll see your raise, and up it:

I feel like a relic..

I used to have disc with kickstart that i needed to use so my computer would boot.

An elegant port for a more civilized time

[–] hansolo@lemmy.today 2 points 1 day ago

Hokey connections and ancient peripherals are no match for a good dongle at your side, kid.

[–] surph_ninja@lemmy.world 14 points 2 days ago (9 children)

Nothing civilized about no hot plugging. Had to restart the whole damn computer, if the cable was loose or out at startup.

You guys had keyboards?

[–] madjo@feddit.nl 13 points 2 days ago

I remember a time when they weren't colour coded...

[–] mercano@lemmy.world 63 points 3 days ago (2 children)

In my day, the RJ-11 jack was for connecting the keyboard, not the phone line.

The original Macintosh keyboard port

[–] Xatolos@reddthat.com 2 points 1 day ago

I remember those days.

[–] iglou@programming.dev 31 points 3 days ago (2 children)

i have a gaming pc built this decade that has both of those ports dude

[–] LifeInMultipleChoice@lemmy.ml 3 points 2 days ago

People knew what I meant when I would verbally say PS/2 in conversation, then people started thinking they were USB because that's what was used in their PlayStation 2

[–] locuester@lemmy.zip 19 points 3 days ago

lol PS/2 ports are the newer ones. There were larger AT ports and ADB ports in addition to the 25-pin(!) LPT port (printer mostly) and COM ports (random peripherals including early mice, pre ps/2)

[–] Blackmist@feddit.uk 11 points 2 days ago (9 children)

I said the real two genders.

I actually wanted a PS2 port because it works with interrupts rather than polling but they aren't really included anymore.

I feel like they don't make boards for people like me who want small boards with a super niche port.

When a MoDT Mini-ITX board comes out with a PS2 port I will buy that instantly

[–] 0x0@lemmy.dbzer0.com 4 points 2 days ago

Listen up, computer, I'm typing NOW. Not whenever you get around to polling the USB device. Sheesh.

[–] qaz@lemmy.world 1 points 1 day ago

Can you actually notice the latency?

Fairly certain my first computer used something like this for the keyboard. I did not have a mouse.

Look at you with your fancy ps/2 keyboard port. Where's my AT port and 9 pin serial mouse.

Are these not still in use?

I've not built a tower in a few years granted, but the last one I built had PS2 ports. Heck it even had VGA for the onboard graphics.
