You probably only need access to DOS on your Communicator. To achieve this you need to create a file B:\NOKIA\INSTALL.BAT and reboot the communicator. From this batch file you can call Nokolisp. If "INSTALL.BAT" exits the normal GEOS shell will start.

Oh no. That would be trivially easy and thus unworthy of hacker folklore. :-)

It was much more complicated and much more impressive than that:

Maybe you'd be interested in this:

But I can't figure out how to install it, while I know how to build nokolisp with MASM. Thus the MSDOS based Nokolisp is more useful, at least for me.

BTW the cited HN posting contains at least one factual error: The Nokia Communicator 9110 was based on an 486SX SOC, not an 80186.

But to each his own.

It looks like nokia.exe is somekind of special version of noko.exe.

For example it refers to B:/NOKIA/COMMAND.COM instead of MSDOS-standard C:/COMMAND.COM.

Oh my word! Is this your project, then?

[timonoko]

Not much of a project...

I think nokia.exe is just made by modifying it while running it and freezing the situation with (make-exe). Not a good practice, imho.

You can glean a little more of the history from this long and involved Reddit thread.

It's hard because you have to work around @timonoko's missing comments, but it's intringuing.
