    oh boy. So that's the beast! Much bigger than I thought. So it's run by a Zilog Z80 CPU. it is essentially a full running computer w/ I/O and peripherals. The block diagram from Hoss indicates that it is connected to the CPU and via one of the Serial Comms connections.

    Not sure how to really offer much but I am still wondering about the old board -vs- new board. Are your pics (the two) of the same board, or the old and new side-by-side? I know you said 'identical'.... Here's what I'm thinking; On the larger board you can see the other smaller IC's w/ tie-wraps and white stickers. Those are some type of programmable items as well.. you might need to move those from OLD Bd. to NEW Bd. w/ the old board PROM. (back to why the new board does not know how to talk to your CPU.... )

    The new board is on the post further back. the new board doesnt have socket for the two smaller chips like the old one does.

    I put the 40:1 eprom in, it moves twice as fast, and indexed to half way between two tool pockets, so I think I should be able to make it spin the servo twice as far for every revolution of the encoder.

    Interesting, I put the chip in with the copied code, and it seems to be spinning.

    I think I got it!

    Copying the old am27c256r eprom and programming it to the at27c256r did it!

    Now its error out on 134 Tool clamp fault.

    The tool clamp has been sticky since i've been putting tools in it, ill try to work it and see if I can get it to work properly.

    I guess the next thing is just cleaning it up, and the coolant tank, I might wait on the coolant though, as I might be moving the machine into my garage soon.

    Bought a hoist and setup a bridge to allow me to move the tool changer over and down. the garage door is 96in tall, the machine is about 111, but if I take the tool changer, hydraulic piston, y axis motor and some sheet metal panels I can get it in.
