I heard there is a program for Macintosh that allows us to use single
Symbolics with many people (like Time Sharing System).
Is there really such a program ? (According to him, it is called
Experlink. I suppose it comes from Expertelligence, but it is not
available in Japan.)
I seriously doubt that there is any Macintosh program which does what you
describe. Turning a Symbolics machine into a true time-shared multi-user
system would require a great deal of software to be written for the Symbolics
machine, in addition to any code which might be running on the Macintosh.
The Macintosh software you are referring to is probably some program which
simply utilizes the EVAL server on the Symbolics machine or perhaps one of the
remote login servers (TTY-LOGIN, TELNET, SUPDUP, or 3600-LOGIN).
The remote login servers, which were greatly enhanced in Release 6, allow
multiple terminals to be connected to one Symbolics machine so that multiple
users can type at the machine simultaneously. This is not the same thing as
using the machine as a multi-user Lisp development system. All of the
Symbolics program development tools are currently oriented toward having only
one Lisp programmer using the machine at a time. Furthermore, most programs
which utilize the window system cannot be operated remotely. However, users
can develop applications which allow multiple users to share the machine
assuming that certain guidelines are followed.
Multiple terminals can be connected to the machine by connecting ordinary
ASCII terminals (or personal computers with terminal programs) to the serial
ports or by connecting network virtual terminals. For information on how to
do this, see the documentation section titled "Remote Login".
ExperLink is a program written by Expertelligence that allows a serial
connection to the Symbolics and a MacIntosh. Experlink requires software
on both the Symbolics and the Mac. I have worked with it twice at trade
shows and it works rather nice. It is NOT any kind of timeshare system.
In fact, the maximum number of ExperLinks that you can have is three (3)
because there are only 3 serial ports on the back of a 367x or 364x.
And again as mentioned previously, there is no software that provides resources
like those on a timeshare, only those provided by remote login and of the
Experlink software. If you cannot get Experlink in Japan, try contacting
Expertelligence here in the states and request some info.
