So that’s why a 2 systems were getting crappy speeds. Yes, 2. It had been used only to split a single drop from another switch between two systems.

New drop, happy clients.

Some stuff here is museum material.

    At least the lathe isn’t running punch tape.

    Don’t upgrade or mess with the control. Disconnect from the network if it’s on it. It should have RS-232. Throw a Pi or other SBC that does serial and a 12V level shifter; use that to feed it programs.

    Also, make an image of the hard drive if it has one and start looking for a spare drive on ebay.

      I’ve got it covered :) - whole duplicate set of hardware & drive image. Recapped the board last year & replaced PSU too.

      I won’t touch the DOS software it uses to actually run the plant, the lads can have at that.

        Rock and roll. I’ve seen bad things happen when someone decides it’s a good idea to modernize a PC based CNC control. (I hate PC based controls). They get their own little fence to live inside where it’s always 1999.
