I have been running my NeXTstation as a Unix number cruncher and
needed to free some more memory: it was paging even with 20 Mbytes
of RAM. To release the memory, I adjusted the /etc/tty file
so that the loginwindow application was not run, and was able to
get a 60 row by 120 column console window by booting as a single
user (after interrupting during power up), then initiating the
multiuser procedure. (Note, if one allows the NeXT to go through
its own booting process, one ends up with a tiny console of some
15 rows by 40 cols, or thereabouts.) This is just fine for what
I need, giving me some 4 or 5 Mbytes extra. However, the console
has a tendency to go into inverse video (white text on black)
apparently at random, and have been unable to figure out how
to reset it to black text on white, which I prefer. Can anyone
suggest how this can be done?

This is just fine for what Since you're interrupting the boot process (something I don't recommend unless you know what you're getting into), why don't you set "verbose test mode" to "yes" from the ROM monitor "p" command? That way, when you boot you'll automatically have the large ROM monitor window (which you would get anyway if you interrupted the boot process). | I need, giving me some 4 or 5 Mbytes extra.

I use ksh and include some sequences in my prompt for highlighting. The last sequence in the prompt turns all highlighting off. This is what I use: STANDOUT="^[[4;2m" NORMAL="^[[4;1m" where "^[" is the escape character (ASCII 27). STANDOUT turns highlighting on and NORMAL turns everything off. Try using the NORMAL sequence when you encounter the white-on-black problem. I've found other sequences, but the above are the ones I use most often.
