Lunar lander startup can take forever (lander uses spin loop to count
|
|
down time for display of starting screen. This may be due to the fact
|
|
that SIMH only tracks cycles in terms of instructions, not execution
|
|
time). To speed up display of the startup screen, deposit a 1 in
|
|
location 32530 after loading the lander program, and before starting
|
|
it;
|
|
|
|
sim> ! Set CPU to a Unibus system type
|
|
sim> set cpu 11/70
|
|
sim> ! Enable DLI device so VT device autoconfigures
|
|
sim> ! with a starting vector of 320
|
|
sim> set dli enable
|
|
sim> set dli line=2
|
|
sim> ! Enable VT device
|
|
sim> set vt enable
|
|
sim> load lunar.lda
|
|
sim> dep 32530 1
|
|
sim> run
|
|
|
|
Lunar lander only needs a small screen area, and can run using a
|
|
simulated "VR14" display, which can fit on many computer screens
|
|
without scaling:
|
|
|
|
sim> set vt crt=vr14
|
|
sim> set vt scale=1
|
|
