The eprom only has the bootloader, normaly you will have to load the software yourself.
Or, in case you have a backup, load the backup.
If you are not able to do that, try to buy a pre-installed board.
Be sure to give all the information of the robot as there are a lot of versions of robots.
Use the newer V4.22P Boot monitor EPROM when given a choice.
Are you buying the replacement Main Board with or without the daughter cards?
You can try IRSA, they helped me several times with this sort of things.
Bought a few items from Global Robots but can't vouch for their service.
Do you have the software disks or a controller backup?
Look for someone with a Fanuc Kfloppy emulator setup. You would still need the software.
If there is a CompactFlash card installed, it is only for backups.
In theory, you could save an image backup to the CF card and restore that after swapping the main board with its CPU and RAM daughterboards.
Just to be clear, the static RAM and ROM will be wiped when they are pulled from the main board.
As an R-J2, it should be a PCMCIA slot adapter. You should see MC (Memory Card) as a device you can select for your backup. You will need to do a controller backup to the MC.
Just to be clear, the static RAM and ROM will be wiped when they are pulled from the main board.
At one point I felt I had nothing to lose with this board, so I pulled the board, unhooked the aa battery and pulled all the cards for an hour, in an effort to reset the whole thing. Unexpectedly it did help but also I kept the software and programs intact.
That's highly unusual but glad it worked!
