Memory? Or lack thereof.

[Bill Gillen]

Hi all,

Just successfully ran my first program, but I had to "butcher" it up to fit in the 4095 byte memory.

My next question is can I add memory, and if so, where could I get it? Also, I am asking if I do get chips, where do they go on the board? I am familiar with adding memory to my pc, but this is different.

Another question I have: Is it possible to "drip feed" my programs into the controller? If so, how would I do that?

Take care,
Bill Gillen

It might help if we knew WHAT control you have.

Does your machine have a "TAPE" mode? If it does, you can usually drip feed in this mode. I thinks it's pretty unusual for a lathe to require drip feeding, though.

For memory upgrades, FANUC has some options, but you may want to consider these guys..

Hi All,

I looked on the motherboard, and found four empty sockets labeled 43256C (and there was a column labeled for two of the sockets (2H) and (3H) for the other two. I then went to ebay and typed in 43256C. Five different chips popped up, so I wanted to ask which is the correct chip?
