Just to clarify, "realtime" isn't about speed (USB2 is far faster than a parallel port) it is about getting the data from the bus exactly when you want it. This is something that USB makes impossible.I don't doubt the speed interface advantages of a card slot interface.

I have started looking into this. What is needed is a way to connect Linux "Input Devices" via HAL GPIO as well as via USB / PS2.
I think that it is possible in principle and I am going to have a fiddle. This would allow you to use some keys of a keyboard/keypad for text entry and some as control keys / switches.

That would make life on my end easier. 
While your at it, feel like expressing the concept via an AVR firmware? (Show us scrap-botters how it could be done better?)
Right now, I'm relegated to a horrendously large python script as the back end for mangling the data stream into an AVR friendly format. (Threaded/Queues/Multiple-sockets,Oh My!)
For your giggling pleasure, I attached the script I'm trying (in vain) to lean up.

Has anyone achieved this, was there a development of such component?
I am looking to connect 7i73 to a matrix keyboard which has letters along with command buttons.

This thread was a long time ago. I did actually make a version of the matrix_keyboard component that could be configured to send keypress events to the system, but I could not be sure that the system calls were thread-safe so I removed that facility.

Is there a way to connect laptop keyboard keys with hal pins to simulate pressing external buttons through mesa card pins?

How do you want to connect the laptop keyboard to the rest of the system?

Sorry I probably asked the wrong question. Pathpilot has many functions that are linked to a particular key or keyboard shortcut. I have an external remote built on hidcomp that generates Hal pins to which I want to bind keyboard keys.

You can _probably_ get most of the same behaviours using
halui
pins, and maybe some
halcmd
macros.
It is possible to emit key-presses, but it isn't quite so easy to send them to the right place.

Thanks for the answer. I will try.
