All you need is a reasonably fast machine, enough disk space for a 1.5GB ! disk image and a floppyXX.fs file from the OpenBSD/VAX distribution. Assuming you're going to run SIMH on an OpenBSD system, install the emulators/simh package from ports. *************** *** 42,48 **** at rq1 /dev/rcd0c set rq2 cdrom ! at rq2 floppy53.fs at xq0 tap:tun0 --- 42,48 ---- at rq1 /dev/rcd0c set rq2 cdrom ! at rq2 floppy58.fs at xq0 tap:tun0 *************** *** 52,57 **** --- 52,59 ---- + For OpenBSD >5.8, replace "at xq0 tap:tun0" with "at xq0 tap:tap0".

+ This configures SIMH to simulate a VAX with a whopping 128 MB of memory, a RA92 1.5GB disk, a CD-ROM unit to hold CD1 of your CD-ROM set, another CD-ROM unit to boot from, and a DELQA Qbus Ethernet *************** *** 78,90 ****

! By setting appropriate permissions on /dev/tun0 you can avoid running ! SIMH as root.

! Alternatively, if you cannot use bridge(4) (for example with some ! wireless drivers), you can use BPF to connect to the network. ! In this case, you can skip the above ifconfig lines and ! replace the "at xq0 tap:tun0" line with a line like this, ! replacing iwn0 with your actual network interface as necessary:
