Who knows what processor/architecture an HSC90 is? Is it a PDP-11? What's it's bus? Sounds like it doesn't mix with UNIBUS or Q-BUS cards at least not looking at the card numbers "Lxxxx" (HSC) vs. "Mxxxx" (UNIBUS/Q-BUS). The reason I'm asking is that I'm looking for the most multi- use of my big-iron hardware that takes up so much space. I believe I will be able to run the console computer of my future 11/78x as a PDP-11. Would be nice if this is possible with the HSC90 as well. I would like to: - provide a PDP-11/RSX-11 environment for my neighbor to play with without getting a dedicated PDP-11. Probably I can do that in the future with the LSI-11 of the VAX 11/78x that hopefully some day will decorate my garage. - try running 2.9 BSD on a PDP-11. Not knowing much about 2.x BSD, I could imagine making the HSC90 into a UNIX-based file server or something. regards, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org
