sorry I mean rlunix, but typing anything kills the CPU and I have to

Anyway, try it, and let us know what happens. How much memory does the
system
have on it now?
64K. I'd like to get another M7891, mine is only 1/2 populated.
If it doesn't work, I can do some experiments and see what's the least
amount
of memory one needs.
There are a whole bunch of parameters which will reduce the size of the
resident OS; if necessary, I can turn them all down to the minimum, and
see
what we get - although just reducing the number of disk buffer may do it.
OK.
As for the applications, it does swap, so
there's no requirement for more
than
one process to be resident at a time, so whatever the largest is -
probably
the C compiler - there only needs to be enough memory left over after the
OS
is loaded, for that one. It looks like the shell is about 10KB, for
example.
If it won't boot, don't trash the disk: if we send you another bootable
disk,
we can make it tiny (only Unix, and enough files to get it running:
/etc/init,
/bin/sh, etc), and if/once it books, you can mount the disk you just
wrote and
move the bootable Unix system image over, and then reboot on the current
disk,
to get to the rest of the stuff.
Do you have two working RL drives on the machine?
I was going to say...yes I have two working RL drives.

The build just finished. When I boot I get the ! prompt, but when I type
rlinux the system bombs and I can go no farther
