If you know anything about this machine, i'd love to : hear from you. : Thanks for you time. : Jason Taubman : taubman@spot.colorado.edu I do know of a unix-like os for the pdp called XINU. It's very small and is only loosely based on one of the early versions of unix but it has the advantage of being VERY well documented and FREE. The documentation is in the form of a hardcover book "Operating System Design the XINU Approach" by Doublas Comer, Prentice-Hall Inc., Englewood Cliffs, N.J. 07632, ISBN 0-13-637539-1. The source and binaries are available from an ftp site at purdue university. This will certainly fill your free time and prove to be quite an adventure. I'd suggest you go look at the book first to see if you feel up to the challenge. It's also a pretty good read, if you like technical stuff. -Jeff Dutky (dutky@wam.umd.edu)
