[Simh] changing from vaxserver to microvax

[Luca Chiaranti]

I've only license type "C" for MicroVax (not type "B" for VaxServer).
I need to change the system type from VaxServer 3900 in Microvax 3900.

The manual says:

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 
and reboot the simulated VAX. 

my system does:
sim> set ptr ena
Non-existent device
sim> 

What's wrong???
