I thought it had a fanuc 6TA control but looking at the Z axis motor I don't think so, is it a Yasnac?
Spent the last 30 years working on Mori's and the like, no yasnacs up here in Canada. Have lots of info. Do you have drawings?
This is the Cadillac of machine tools.
Ray.

Cadillac is right on !  This thing is one big hunk of old iron...its a beast at 5500 LBS. 

Yasnac is the servo types, I have a poor condition connection drawing of an SL3 Lathe and a good detailed connection / interface drawing for the Spindle Control.  I will post these once I scan them in.  If you have anything on the SL1 I would very much like to see it :)


 
Were you ever able to scan the connection drawing and spindle control scanned in? 
I am about to embark on an SL-3 retrofit and I would be very interested in these. 

 Please let me know. 
Thanks, Jay

This one defo needs a bump!   Potentially a really nice machine you have there.

If it were mine I'd be swapping out those old servos and drives for new AC brushless gear.

My Hardinge also had DC spindle motor (5hp), and I swapped it out for a decent iron framed 4hp AC motor and Siemens MM440 drive.   Saved me much grief.

I was curious to know if there are any updates to this lathe conversion.
I'm very interested.

Yes, I'd love to hear what the update on this is as well. I just had a 1983 SL-1 with a Yasnac 2000GII Controller go down with a bad encoder code. This is only the latest in a string of "issues" we've been having with it in the last few years (all having to do with the old wiring and controller). I need to dig into this latest error but the machine is in great mechanical shape and I see the writing on the wall that it won't be long before either it's time to dismantle for parts or do a retrofit on it.

Bummer, mind if I ask if it's been stopped due to problems with the retrofit or due to other issues?

Its just not a priority at this time, so its on the back burner for now
