Nova's have standard assignments for device addresses, and if you change
them, standard DG software won't run.
SimH's list is contained in nova_defs.h:
#define DEV_MDV 001 /*
multiply/divide */
#define DEV_ECC 002 /* ECC memory
control */
#define DEV_MAP 003 /* MMPU control */
#define DEV_TTI 010 /* console input */
#define DEV_TTO 011 /* console output */
#define DEV_PTR 012 /* paper tape
reader */
#define DEV_PTP 013 /* paper tape
punch */
#define DEV_CLK 014 /* clock */
#define DEV_PLT 015 /* plotter */
#define DEV_CDR 016 /* card reader */
#define DEV_LPT 017 /* line printer */
#define DEV_DSK 020 /* fixed head

#define DEV_MTA 022 /* magtape */
#define DEV_DCM 024 /* data comm mux */
#define DEV_ADCV 030 /* A/D converter */
#define DEV_QTY 030 /* 4060

#define DEV_DKP 033 /* disk pack */
#define DEV_CAS 034 /* cassette */
#define DEV_ALM 034 /* ALM/ULM

#define DEV_PIT 043 /* programmable

#define DEV_TTI1 050 /* second

#define DEV_TTO1 051 /* second

#define DEV_CPU 077 /* CPU control */

How do you associate a given "device" on the simulator with a Nova device
code, so that when a program does I/O to a given device, the simulator
knows what attached file to use?
This seems pretty basic, but I can't find it anywhere.
Just getting back into simH after being away for a while.
