I am pretty sure it is from 6Y080L0 series. I will need to determine if I can get the chassis, or at elast the label to determine complete model number and the 4 letter code for heads (eg N,M,G,A).
What do you mean I will need to align the platter? Surely with a single platter there would be no need for alignment? I am not concerned about the PCB, in my experience most of these share compatible PCBs with no need for ROM swap, and I have many of these PCBs available to me.
My biggest worry is that the media is full of fingerprints, I do not know of the original failure, unsure of the top and bottom of the platter, and am not certain if I will be able to match the head type without the label.
I am sorry to say, but looks like You are not in the case to can do this recovery.

The rom:
The rom, independently from the labels, have some adaptive info about the SA head and its values+ preamp to read in the SA.
So, You have right, the most of the 6Y080's pcb are compatible, the 80-90% starts from the H3, but in this case a little more complicated, as you see.

The alignment:
The calypso is sensitive for excentricity.
If you simple put the platter in, the drive maybe can't get readyness, because can't trace the track wich runs on elliptical ring.
Additionally, sometimes the excentricity generates vibrations, and easily can crash the head and scratch the surface.
(beto have one of this cases, ask him, i suggest...)
I can handle the platter-excentricity issue in this case.
(unfortunately at this point, not the track-excentricitly issue.

)
