Apparently the machine has seen an OS update (was installed?) in 1988 so
I'd suspect it has at most System VR3.2. Might be an NCR Tower 32/400, the
housing has a model number (#34700202) but no other label. The box is still
fully operative and in use by the customer, so I cannot simply take it home
and rip it apart.  ;)

I've emailed NCR for further information and hope they do answer. They
still have OS patches on their web site, not too bad for an eleven year old
architecture. But then, you can still get MacOS 1.0 from Apple.

The target in question is mac68k, and I'm pretty sure we do not do SysV
emulation, yet.

Great!
