I was hoping that Tenon would have a direct connection to the Internet (still about 2 weeks away), but until then, I can be reached as aksguest@engrhub.ucsb.edu. If anyone has any detailed questions, feel free to call Tenon, or send me mail. We will soon post a formal product announcement to comp.sys.mac.announce. The MachTen demonstration at Interop was demonstrating an early version, and was basically a demonstration of MachTen's ability to run the Mach kernel and 43BSD UNIX applications on a variety of Macs. Final release will support the ability to run Mac applications as multitasking Mach processes. I'll now try to respond to some of the messages I found.

There is no reason to run NCSA Telnet with MachTen. MachTen comes with all of the standard 4.3BSD applications including user/server telnet, rlogin, rsh, ftp..... Both client and server NFS are also included. In fact, at Tenon we have an interesting configuration where we're running a diskless Mac Plus that boots and mounts NFS filesystems on an SE. One other minor point. At Interop we had SL/IP connecting two Mac SE's modem ports, and we were demonstrating connecting a terminal on another Mac's modem port to act like a standard user's terminal (with a getty/login process running on it).

That's because on those >machines applications DON'T run in supervisor mode. That the IIsi and IIci, and for that matter the Mac Plus and IIx were left off of the list was an oversight. MachTen runs on all of these platforms. The contents of the 680X0 status register (where the supervisor/user mode bit lives) at the time a program is launched really has no bearing on MachTen's portability.
