Ultrix 2.2 doesn't boot from the distribution tape, it boots from a
standalone "boot" tape.  What you want is
http://bitsavers.trailing-edge.com/bits/DEC/vax/ultrix/2.0/AQ-JU00C-BE_ULTRIX-32_2.0_SA_87.tap.gz
which, despite its name and the directory it is placed in, is the TK50 boot
tape for Ultrix 2.2.  Boot from that.

I honestly don't remember how I installed 3.0 as the standalone boot tape
is missing.  If you can install and get comfortable with 2.2, and if you
can install the 2.3 patch successfully, let me know and I'll try and
remember how to get 3.0 up on SIMH.

You should read
http://bitsavers.trailing-edge.com/pdf/dec/vax/ultrix-32/3.0/AA-LY24A-TE_ULTRIX-32_BasicInst_Microvax3300_1988.pdf
; I do not recall the install process being significantly different between
2.x and 3.0.
