[Simh] [simh] Nova Device Codes

[Bob Supnik]

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_CLK         014                             /* clock */

#define DEV_DKP         033                             /* disk pack */
#define DEV_CAS         034                             /* cassette */
#define DEV_ALM         034                             /* ALM/ULM 
multiplexor */
#define DEV_PIT         043                             /* programmable
