All of those are, I think. They build the 0i and 18i but the three thru
eleven haven't been in production for a while. You see a 15iMA or B on the
Chiwanese stuff from time to time but the modern builders are using thirty
series hardware.
I see 20 series hardware on CNC lathes once in a while.
Fanuc has some parts for the six but they are more expensive than the
machine in question. The best bet is rebuilding and that isn't exactly cheap
either. I know guys that buy machines to have spares for their existing
controls. Hitachi Sieki has been out of business for a decade or more.

I bought a shared memory board from Fanuc to fix a popped serial port on a OTc. I know
there is a second port on that board so I asked them how much to turn that one on. The
said more than buying a new board we have in stock.

A firm that is history real concern. I can get parts for an 83 okuma, no problem. I
suspect if we blow a memory board they can help us.

I'm combining your two posts at this thread level.

It will be important to be sure and back up everything, including the PLC
ladder, before moving the machine or even disconnecting the power. There is
also a place that sells Fanuc battery replacements. In this vintage, it
isn't uncommon to move one of them 50 feet and have them not run again
without major fiddling around.

Learning to backup that puppy (the Hitachi Seiki) better be the first thing on the buyers
list.

The popped memory board was ez stuff until I found out there are parameters and PC
parameters. I didn't have the latter. The techs that had delt with the machine for the
previous 10 years never captured them either.

Lucky for everyone, we had two other machines, one had the same PC parameters. The second
set I tried made machine very happy. Google Memex and find tips on backing up your
control for those that are not up to speed on this.

Less than 2 months after this deal, we moved a Mori Seiki SL25 ~100ft and guess what? Yup,
can't remember what 9xx series error it was but ram was corrupt.

Oh those backups I made of those machines sure came in handy.
