Ok, so I looked it up :

##
The system type is controlled by a "magic byte" in the CPU's boot ROM.
By default, the system type is a VAXserver 3900. To change the type to a
MicroVAX 3900, patch the boot ROM as follows:
sim> set ptr ena
sim> att ptr ka655x.bin
sim> ie ptr 4
4: 2 1
sim> det ptr
##


Unfortunatly, in my universe where everything works just a tad differently:

bash-3.2# bin/vax

VAX simulator V3.8-1

sim> set ptr ena
Non-existent device

sim> att ptr ka655x.bin
Non-existent device

I guess I will have to read some other FAQ on how to get the commands in
the first FAQ to work :-( ;0-( :-(

I have some valid 4000-600 licenses, and the All Mighty MVII licence has
the magical MOD_UNITS on it.
