Apologies for not having pictures: time has been limited. I de-rusted the chassis, and it looks pretty darn good. The zinc plating unfortunately did come off from part of it, but that's ok. I will have to look into learning how to re-plate at some point.
Thus far, a list of things to be looked at/fixed:
-The speaker female end connector also corroded into dust inside it's housing. I removed it and stripped back the wires, but am uncertain as to how to find a direct replacement type (there are thousands on the usual supply sites).
- The PRAM settings don't appear to stick. I have to see if this is due to some faulty work on my part regarding battery holder installation.
- The floppy drive, after being cleaned/lubed is having some issues ejecting. I swear, the alignment of it with the front is always tricky. It also never seems to eject the same as it once did. I really wish we had access to some kind of Sony original spec manual for the drive, but it seems to have been lost to eternity plastic. No one knows what the original lube was, nor what the specs were. So far, I can't locate any Sony documentation at all.
Otherwise, it works just fine. I think the internal HD is shot. had to smack it around to get it to spin, and the drive does not appear mountable. I actually found it in HD SC Setup and also by looking for missing disks in Norton when I hooked it up to my PT Pro, but I can't seem to find a way to try and force mount i. It has the name "LO LO BEAN" (you can't make this stuff up).
That is it so far. Back to work tonight...
