I've downloaded a PDP-11 Emulator in order to play the original Lunar Lander. Unfortunately, the Lunar Lander program can only run on the DOS version of the emulator. This, I figured was a piece of cake with DOSBox.

The unfortunate part is that DOSBox refuses to admit it has enough memory to play the game; it spits out....

?Insufficient memory

I checked around, and typed in....

memsize 96

.... and it still didn't work. I took the risk of setting the memory to more than what I actually have.

I'd like to know if there's a way to fix this. I run Windows Vista Home Basic (yes, Vista), I have an Intel Core 2 Duo @ ~2 GHz and have 2 GB of RAM.

You need to turn EMS off before running E11.

Either using the command

Z:\>ems off

before running E11, or editing dosbox.conf with ems=false.

For some reason, the computer refuses to allow me to save the config file, and shutting off EMS while in DOSBox has not worked.

"Access to C:\Program Files\DOSBox-0.72\dosbox.conf was denied."

It's Vista. I know it is.

EDIT: Ok, I managed to save the config file. Now, it still doesn't work.

In Vista you don'T have permission to write to files in the /program files/ directories. Either assign yourself the correct rights for dosbox.conf or make a new one at a location you have the necessary rights and start Dosbox with this conf file (see the readme).

In case you missed the edit (out posts were close), I managed to get the config file saved.

Unfortunately, I still can't run E11.

Yes it was off, but I'll try again anyways.

EDIT: No, it still doesn't work.

And how do you know it is off?

Typing "EMS" into the console will result the response, "false".

Ok 😀

Strange, it worked for me. Created a C-drive for DOSBox, ran the INSTALL.EXE which installed in C:\E11. Tried to run the E11.EXE without modifications to DOSBox and was greeted with the memory error message. Turned EMS off, re-ran E11.EXE and it started up.

Ahh - I guess I turned off XMS first, saw that didn't work, then turned off EMS and it worked. So both needs to be off.
