    Anilam does still exists but I can not afford what they want to fix it. They have a flat rate no matter what the problem is. Yes there are 3 EPROM S on there

      ... up ... I m not sure if the particular processor you re talking about is the one I m thinking of, but Motorloa made several different versions of the 68000

        I'm not sure if the particular processor you're talking about is the
        one I'm thinking of, but Motorloa made several different versions of
        the 68000 processor including a version with an 8 bit data bus that
        was to compete with the 8088. It is not pin compatible with other
        68000 chips to my knowledge. As for repairing the cnc mill, check
        some cnc sites to see if you can find any ex field techs with
        experience with those machines. Or look for customers who may have
        old ones they are tossing out when they upgrade.

        Good luck with your repair, Steve, and holler if anything seems awry. :o) -DM ... From: alienrelics To: Electronics_101@yahoogroups.com Sent: Friday, March 01,

          Hi, Dangermouse. AlienRelics here.

          You are correct, there is no programmable ROM in the 68000P8.

          I agree, I'd be pretty paranoid about losing whats on the EPROMs and
          ROMs. If they have paper labels covering the EPROM window, a lot of
          times the adhesive dries up and the labels fall of. Can take a long
          time for stray light to erase them, but why take a chance?

          the net, it doesn't look like it does, so you should be safe
          replacing it without worrying about the date code.

          memory, and if they do, you may be sunk unless someone SOMEWHERE
          knows what should be programmed into those chips.

          EXCELLENT. If their service proces are too high (no surprise), perhaps some of their parts prices will be tolerable (unlikely, but possible). If you DO get

            If you DO get all the schematics and codes, you will at least have the tools so that others might help you use them.  :o)
