Cool, typical of many non horizon NS* systems. A bit of this
and that.

Uhm what are you using for keyboard input if the VDM is output?

I did some looking and find nothing that says Lifeboat did 1.3
for NS*. The copy I have is 1.403 for NS*. They may have
done 1.3 but the timeframes for 1.3 and Lifeboat are off.

Sounds like you need more ram. Get another 16k for safety.
A cromemco ram16 or ram17 should be easy enough to find
or other 64k static.
