If all the same not a working board. Is there a method or test? To determine if the board is not working?
I have such a picture, but here are other disks for the system and another proms.
Is it possible to replace the computer with a more modern one, without changing the motor drivers and power supplies?
For example, I found such a system https://newker-cnc.en.alibaba.com/product/607505…ction_line.html
Or suggest how to write programs if only the board is replaced.
