How do I add more pty/tty entries so that Terminal and Stuart (and any  
other terminal applications) can open more windows.  I've tried using the  
MAKEDEVS script to actually make the devices, but when I reboot the  
machine the terminal applications still stop making terminal windows after  
ttyqf.

Thanks for any help you can provide.

You cannot.  The pty kernel device driver is configured for 32
devices, and it does not dynamically allocate its data structures.  To
see the gory details, look at the BSD pty driver, available on UUNET,
etc.  The NeXT's pty driver seems to be essentially unchanged in
architecture.

I would tell you that I think the number of ptys has been increased in
3.0, but that would probably violate some beta test agreement.
