About
A small graphics program that draws a wireframe pyramid turning in three dimensions. It prints CALC. and a line of asterisks while it works out the frames, which takes a couple of minutes on the Einstein, and then draws the shape over and over at new angles.
What It Is Made Of
It is not BASIC source but a compiled program, and it names its own toolchain: the file carries the ZBasic runtime's messages (Not Enough Memory, Bounds Error, Break) and the string PYRAMID.BAS, the program it was compiled from. The library holds ZBasic itself, and this is what its output looks like. No author is named anywhere in the file.
The File Has No Extension
On the disc it is called PYRAM, with no .COM on the end, which is how it was deleted and how we have left it. DOS will not run it under that name. Copy it to a disc of your own as PYRAM.COM and it runs.

Where It Came From
Recovered as a deleted file from the ZBasic disc in the library with einstein_dsk_recover from the Einstein Disc Tools, intact. Given where it was found and what compiled it, it looks like somebody's own demonstration of what ZBasic could do.
