There is a early version of Samba Client I think 1.4 on RTSI for OSK and 
ISP (The original IP stack for OSK).  I couldn't get it to work at my 
old job, though I did get NFS to work on that machine, but it had 
problems with Solaris, maybe that was Samba's problem also.  I know that 
this was a 68040 based VME Machine.  KAQ9 is a TCP/IP Stack but done in 
an application mode instead of a Driver/Module mode.  I really wish my 
MM/1B and Coco was on my network.
