Performance was identical to 4.2 (which isn't surprising...), except that the RA81 driver bugs of vanilla 4.2 were missing. Reconfiguring using the binary was straightforward-- part of DEC's rewriting was to make this work. So far we have seen no software support other than pretty manuals. The DEC field installation force let us install Ultrix ourselves since we knew more about it than them. We have gotten no software upgrades so far. I don't know how many if any of the many many bugs reported since 4.2 release were incorporated into our release of Ultrix (but the RA81 driver was fixed). Our source code for Ultrix hasn't arrived yet so we haven't had a chance to check. (Because of delays in getting the Ultrix source we switched to the BRL version of 4.2 after about a month, and are still running that.) -- Spoken: Mark Weiser ARPA: mark@maryland CSNet: mark@umcp-cs UUCP: {seismo,allegra}!umcp-cs!mark U.S.: Computer Science Dept., University of Maryland, College Park, MD 20742
