Console terminal
Type into the box and press Send. The emulated keyboard registers are at 177560/177562; printer registers are at 177564/177566.
Program and media loader
No external program or disk image mounted.
V3.7: LOAD OCTAL now auto-detects both 16-bit octal word lists and colon-formatted octal byte dumps. It also sets the entry address, updates the program information, and refreshes the memory display.
RK05 / raw disk image
Mount a raw .dsk or .img image for sector inspection and experimental block access.
Loaded program information
No program loaded.

Console operation
Every visible control is active: the 22 switch-register paddles, POWER/LOCK/OFF selector, PARITY HIGH/LOW,
processor-mode selector, display selector, and all seven console keys. LOAD ADRS copies the switch register to
the console address. EXAM reads memory and advances by two. DEP writes the low 16 switch bits and advances by two.
CONT resumes, HALT stops, S INST executes one instruction, S BUS performs a bus-cycle display, and START begins at
the console address. The processor supports a practical PDP-11 instruction subset, addressing modes 0–7,
branches, subroutines, stack operations, byte/word memory access, console terminal I/O, a two-pass assembler,
DEC absolute paper-tape loading, raw binary loading, snapshots, and experimental RK05 image access.
