The machine belongs to friend. I plan on helping him replace the main board and convert to linuxcnc when the original one finally stops working. For now, it aint broke, so i'm leaving it.
We thought the main board was dead about a year ago, as we got a RAM error on startup and nothing worked. Multicam wanted a crazy price for a replacement. I guess because they're old and you have no other choice (if you don't know how to setup linuxcnc)
I have a Mesa 7i96S ready to go to get him up and running ASAP when the time comes.
I would probably replace the drives with a Gecko drive if one fails.
Let me know what you end up doing...
