Re: [TUHS] 211bsd: kernel panic after a 'here document' in tcsh

by jnc＠mercury.lcs.mit.edu

> From: Jacob Ritorto > Where might one find the list of trap_types Look in: http://minnie.tuhs.org/cgi-bin/utree.pl?file=2.11BSD/sys/pdp/scb.s which maps from trap vector locations (built into the hardware; consult a PDP-11 CPU manual for details) to trap type numbers, which are defined here: http://minnie.tuhs.org/cgi-bin/utree.pl?file=2.11BSD/sys/pdp/trap.h and handled here: http://minnie.tuhs.org/cgi-bin/utree.pl?file=2.11BSD/sys/pdp/trap.c > and cpuerrs? That just prints the contents of the CPU Error Register; see an appropriate PDP-11 CPU manual - 11/70, /44, /73, /83 or /84 for what all the bits mean. Also the "KDJ11-A CPU Module User's Guide", which also documents it. In theory, there's also a KDJ11-B UG, but it's not online. If anyone has one, can we please get it scanned? Thanks! Noel
