Real time kernel is back, but again no USB.

You can try the SD card image image here for a full clean install. I think that it is woking on all but Pi4 8GB and Pi400:

Just made my first cut with the new image. Thanks Andy Pugh.

If you try to start Chromium, it gives some message about lack sand box. Something to do with the kernel.

But that doesn't matter to me. In my experience, Chromium doesn't work well on a Pi4. I use Firefox.

In case you never figured it out, that round socket is most likely for a rotary indexer. As far as I know, all hurco machines with the B control came with a port for one. It is simply a set of contacts telling the indexer to index, then an input from the indexer to let the control know when it's finished indexing.
The old hurco controls came in two variants, the B and BX. The B control had a programmable resolution of 0.001", and included no RS-232 ports. The BX control was an upgraded control that had some advantages. It was programmable to 0.0001", had two RS-232 ports, included G-Code support, and had an extra 8k of memory. The BX MPU board is recognizable from the B board by the presence of two ribbon headers on the top of the card, and a block of jumpers in the lower right of the card to set serial port baud rates.

The original hurco control is excellent for conversational programming, and is easy to learn. However, it is limited if you don't have the BX.

I'm pretty sure this unit is/was a "B" control.

The computer, console, and the cable the runs in between them has been removed. Before they were removed, I could sometimes get a prompt on the display, but could never get the tape to load.

And BTW, all this stuff was removed intact. Its all still in one piece in the machine owners (not me) attic. If somebody needs B series computer parts, they might be available.

New LinuxCNC/RPi4 based console finally done.

Paint match turned out very good.



Next up is to try and fix the head. Brake doesn't work. Low gear makes ugly noises. And the quill has about 0.005 runout.

I want to replace my old computer and keep the Servo Drives and Servos in my KMB-1, which has been upgraded to BX. I would like to know the wiring you used on the TB-3 and TB-8. Thank you.
