I tried running the thread slower but it got even worse . I think I'm going to use direct inputs on the 7i70 . It won't be too much hassle, but i'll get to that after i setup the toolchanger .

matrix keyboard can be used in a couple of ways - you didn't mention how you are using it.
it can scan a matrix keyboard and convert to individual hal pins or
it can read a scan code (usually from mesa 7i73 or panelui program) and convert it to individual hal pins.

I assume the first.
One problem is that matrix keyboards are momentary on buttons that share wiring.
A rotary switch always has at least one output closed.
This could bring in key roll-over problems.

I would suggest mux16 or mux_generic that have included debounce options for your rotary switch.

my 2 cents

I use mux components but the created hal pins are not correctly decoded .
This specific board has diodes on all inputs and was successfully used by the fanuc .

I got the outputs going with a primitive component .
It's far from elegant, but it works .

B) .. perfect!

I use a similar one (I named it simplychoice) for make simply choice bit/pin out from several input bit/pin condition ... work from 2012 everyday without any problem ....

If work no touch!!

Thanks for the information - I am learning LInuxCNC and one of my "thinking cases" is how to interface a panel similar to yours.

If you don't mind me asking - did you jot down some sketch (on paper) on the physical side of your solution? It would be a nice complement to the code abode. Many have talked about retrofitting old control panels but I haven't seen any thorough write-up.

Cheers Hans

When I was trying to understand how the board worked I went through the schematic .
I didn't get it with all the details but enough to give me an idea of how it works .
I'll have to get a few shots of the paperwork .

[This is to give an idea of the original mori circuit board .
The output side uses D triggers as a one bit memory . At the time I didn't write down the IC numbers but the circuit speaks for itself .

For now it seems to work well with matrix_kb . I moved the selector switches to direct inputs and run it in a 4ms thread . Response is good .

I think there's something wrong with the permissions for the photos - I just get "You do not have permissions to access this page" instead of pics!
