<<One additional factoid I will throw in for HP-IB on 9X9 boxes while I think of it: Although peripherals seems to work O.K., be warned that there are some things you can run that will be distinctly unhappy to find an HP-IB card in a 9X9 chassis... One or more of the SYSDIAG utilities, for example (forget which one(s); Steve probably remembers): Run the wrong one on that path and you will crash your system....>> The following diagnostic modules appear to work fine (or at least they did the last time I tried them; we don't have the hardware for some of them any more): CIPERLPD, HPIBDDS, HPIBDIAG, REELDIAG. Anything else might be trouble. Steve
