Installing Ultrix 4.5 on MicroVAX 3100

Ultrix 4.5 on a MicroVAX 3100 I wanted to install Ultrix on my VAX, described here. Here is some log regarding installation. The installation was already documented by various people, so it is nothing new, and credits go to these people. Ultrix version used is from 1995, so 28 years old. The following screenshot shows, after installation, some DEC Windows tools, remote displayed on my Linux machine. You see 2xdtterm, dxpaint, dxpuzzle, dxnotepad and dxclock.

Digital DEC MicroVAX 3100

Digital DEC MicroVAX 3100 I bought this as a fully working machine. Series BA42A board and KA41A CPU. So this is a Microvax 3100-10. 16MB RAM. The machine contains two harddrives. One contains a VMS operating system, the other one a NetBSD installation. So it can run both VMS and UNIX. Contains a DHW-42-AA (also called: DSH32-B?) extension board. It offers 8 additional serial lines (for terminals) and 2 synchronous lines RS-423.
