Denford Software & Machines

I have a Cyclone with Fanuc OT which had been left in a collage for a number of years resulting in its batteries going flat. ( Big Trouble I know)
If anyone has a similar machine to this Im looking for a copy of the S'RAM BACK UP so I can get started on fixing it.

Serial cy27070 c
Date of manufacture 1990
Serial of electrics 9123227

Any help on this would be appreciated

This one is long, but lots of tips related to Fanuc RS232 and parameters (especially the bit about not turning off when LSK is flashing!)

Hold down EOB when outputting to backup the 900 parameters as well.

It WILL be worth writing the 450 diagnostics & 900 parameters down just in case!
