I have some old pyramid dump tapes (OSx4.0) that I would like to be able to read after the pyramid is gone. I'm currently wrestling with the sources in an attempt to create a restore program that will run on a vax. Its not so difficult to strip out the part about conditional symbolic links, but there are other issues, such as byte swapping, and reading in the correct size headers etc. I've had some limited success, but the end isn't too near. I probably should have posted this request before beginning, but I guess I underestimated the task (or overestimated my brain power). So, if you've had any luck with creating such a restore program, I'd like to hear from you. (We also have suns that could be used, but I haven't got sources for sun restore.) Please e-mail to me as I don't read this group. I'll summarize if there's interest. Thanks. -Brian Parent e-mail: bparent@ucsd.edu phone: (619)534-6090

The first thing we did when we shut down our Pyramid was to hack the 4.3BSD restore program on our VAXen to read Pyramid tapes. I have made these changes available for anonymous FTP on mimsy.umd.edu in a file called pub/pyrestore.tar. If you don't have Internet access, I can mail it to you. It is a series of diffs, so you will need the 4.3 restore (this is what we run on the Suns too. At least it is a starting place). The 4.3 restore is smart enough to do byte-swapping on its own, so our changes mostly just deal with block size and conditional symbolic links. Pete
