Help with Sony NWS-3410 and NWS-3260

Hello.

I'm trying to restore a Sony NWS-3410 (desktop) and a Sony NWS-3260 
(portable), both with a broken hard drive.

I'd like to run NetBSD and NEWS-OS side by side, by installing NetBSD in 
one of them and original NEWS-OS on the other.
Unfortunately I was able to find someone that has both those machines 
(or some other compatible 1:1) and the original installation media from 
Sony for NEWS-OS 4.x (the ISO image is stored in different repositories 
on the web, while the boot floppy is missing, I was not able to find it 
anywhere).

Can I get in touch with somebody that already installed NetBSD and 
NEWS-OS on these machines? Can somedoby share the original installation 
media? As wrote above, unfortunately both hard drive are broken, 
therefore it is impossible to dump the and/or move from one machine to 
the other.

Thank you in advance.

Kind regards,
