Can arduino read PS/2 port?

Projects Programming
1

I have a standalone PS/2 numeric keypad for a laptop sitting in my junk drawer...was thinking maybe I could use it for something? Maybe a directional control of some sort, in leu of a joystick?

2

I did a quick search with three words 'Arduino' and 'ps/2' and 'keyboard'.

guess what popped up

http://www.arduino.cc/playground/Main/PS2KeyboardExt2

dunno if this is what u need but there was mouse stuff as well

Start with Arduino Playground - PS2Keyboard, it has the connection details.

Hmm, looks like something I can play with then. Not sure what for, but I bet I'll find something. I'm one of those people that hordes cables and contraptions. I have 15 tubaware stackable drawers of computer cables and parts...75% of them are obsolete (I even have a running laptop with windows 95 on it...)

I imagine a lot of us are people like that. I still have an IBM PS/2 model 80, that booted up to DOS last time I tried it.

No IBM PS/2 in 1980 !

look at wikipedia 'IBM PC', PS/2 came in 1987 ;o)

Not 1980, Model 80 - http://john.ccac.rwth-aachen.de:8000/alf/ps2_80041/

Unfortunately the hard drives have packed up, and I don't have any MFM drives.

I have even older PS/2 model 30-021. Just few days back find it, but it is too fast (8Mhz 8086) for the games created for 4.77Mhz PC. I need to drop the speed with software, or maybe I change the chrystal?

Cheers,
Kari

That's it? My shop is overflowing with stuff like that; somewhere I have my first laptop that ran DOS 6.2 (20 meg hard drive - woo!). Then again, I have sitting on a shelf an Altair 8800, along with some old core memory, and a 9-track tape.

I bet if I dug deep enough, I could find a punch card or two (I'm sure some of the real old-timers on this list though could pull out a fully sorted deck)...

:smiley:

Punch card ? That look an interresting Arduino project...

About PS/2 keyboard and keypad. I did a project using a AT keyboard and AT Keypad ( the old IBM keyboard ), the library work just fine ( if I remember, it contain a few bugs - I fix it ) and I notice the pinout is the same as AT keyboard/keypad.

So to answer your question .... YES As long you connect properly, you will be fine.
