[Simh] weird question about the VAX's DZ port

I found this site:
http://anachronda.homeunix.com:8000/~rivie/cpm-vax/
And I thought it'd be interesting to see if either the
11-780/MicrovaxII simulator could run this... So I noticed from the
source the following:
"A MicroVAX 2000 DZ at address 200A.0000."
So looking at the 11/780's output of show dev:
DZ, address=2013E040-2013E05F
And from vax780_defs.h:
#define IOPAGEBASE 0x2013E000
#define IOBA_DZ (IOPAGEBASE + 000100) /* DZ11 */
which doesn't quite seem right... I'm guessing the 000100 is Octal,
not Hex? Even changing it to 0x200A0000 seems to do nothing in the
source... Where should I go to modify the base address of the DZ?
TIA
Jason
