Sirs:
I have both the archives of the DOS version by Bob Norby.
The are ver 5.0, and 5.1 color.
I think that they were ported on the DEC Rainbow.

Would you be interested in making those availble for download or should they just disappear into the bit bucket?

I'm assuming that the archives include the source code.

Yes, I'd like to see this added. I still play the 5.1 color version from time to time. The play experience is different from the old VMS version I first used, but it is still fun.
