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 | |
