(Both boxes are running Linux; one is the host for my SIMH TOPS-10
system, the other for KLH TOPS-20. Now I have to figure out how to
tickle them into giving a serial port login; it seems I'd forgotten
the last time I set them up they must have been configured to go
straight into X, so now the boot ends with...
Master Resource Control: runlevel 5 has been reached
Skipped services in runlevel 5: personal-firewall.initial
INIT: Id "1" respawning too fast: disabled for 5 minutes
INIT: Id "2" respawning too fast: disabled for 5 minutes
rather than a login prompt! Grrrrrrr... one thing after another!
Thanks for help.)

'No greater love hath a man than he lay down his life for his brother.
Not for millions, not for glory, not for fame.
For one person, in the dark, where no one will ever know or see.'
