Your device flags (e.g., UNIT_2708) must be shifted by DEV_V_UF as well, and the same for the unit flags and UNIT_V_UF. For example: #define UNIT_V_MSIZE (DEV_V_UF) /* ROM Size */ #define UNIT_MSIZE (0x3 << UNIT_V_MSIZE) + #define UNIT_2708 (0 << UNIT_V_MSIZE) /* 2708 mode */ + #define UNIT_2716 (1 << UNIT_V_MSIZE) /* 2716 mode */ + #define UNIT_2732 (2 << UNIT_V_MSIZE) /* 2732 mode */ + #define UNIT_2764 (3 << UNIT_V_MSIZE) /* 2764 mode */ The problem is that when you specify your modifier as: { UNIT_MSIZE, UNIT_2716, "i2716", "2716", &EPROM_config }, ...and you "SET unit i2716", SIMH is ANDing the flags with the complement of UNIT_MSIZE and ORing with UNIT_2716. As it is written, you're clearing bits 16 and 17 of the flags word but then setting bit 0 (instead of bit 16). It also appears that your mask for UNIT_BADDR isn't large enough to encompass all of the values (should be 0x1F instead of 0x0F). -- Dave _______________________________________________ Simh mailing list [email protected] http://mailman.trailing-edge.com/mailman/listinfo/simh
